As an early contributor or seed donor, Seed participants wrote down a 12-word mnemonic seed phrase that was generated by the DFINITY Chrome extension. To create an identity, seed participants must derive a private key from their seed phrase and import that private key into the DFINITY Canister SDK. This step is required before seed participants can take control of their neurons.

The safety and security of the seed participant's private key is their responsibility and there is no substitute for planning ahead, bringing the right equipment, having the right skills, and using good judgment. It is strongly recommended they proceed using an air-gapped computer to reduce the risk of having their private key compromised. Depending on the hardware available, they might want to physically remove the network controller, microphone, speakers, and other components, or disable them in their BIOS. Covert channels can be established through a variety of different mediums, including sound, light, radio-frequency, and physical media. Be sure to evaluate the capabilities of your system before settling on a configuration that makes sense for you. If one is unsure, one should consult with a computer security expert. Do not contact the DFINITY Foundation for help with securing your environment.

===Step 1f: Derive and import your private key===
 +
 +
Derive your private key from your seed phrase.
 +
 +
<pre>
 +
$ echo $seed | keysmith private-key -f -
 +
</pre>
 +
 +
 +
This creates a file identity.pem containing your private key. Import your private key(s) into the DFINITY Canister SDK and then remove it from the filesystem.
 +
 +
<pre>
 +
$ dfx identity import <name> identity.pem
 +
$ rm identity.pem
 +
</pre>
 +
 +
 +
Here, <name> is an alias that you can choose arbitrarily for your identity, e.g. "jane". The command above displays output similar to the following:
 +
 +
<pre>
 +
Creating identity: "jane".
 +
Created identity: "jane".
 +
</pre>
 +
 +
Make your new identity the currently-active one.
 +
 +
<pre>
 +
$ dfx identity use <name>
 +
</pre>
 +
 +
The command above displays output similar to the following:
 +
 +
<pre>
 +
Using identity: "jane".
 +
</pre>
 +
 +
At any time, you can list all available identities with
 +
 +
<pre>
 +
$ dfx identity list

==Step 2: Take control of your neurons==
 
==Step 2: Take control of your neurons==
 +
 +
You will receive your tokens inside a set of neurons that have been pre-created for you. The number of neurons will total 31 or 49 depending on whether you are an early contributor or seed donor, respectively. Your tokens are disbursed equally over these neurons. Claiming your neurons is the process of obtaining control over your neurons. It is done for all neurons at once.
 +
 +
Your neurons differ by their dissolve delay. For an explanation of dissolve delay see Instruct the neurons you wish to unstake to dissolve below.
 +
 +
To claim your neurons, you need to sign and send a message to the Genesis Token Canister. You can accomplish this in one step on a networked computer using dfx canister call, or as two separate steps, one on an air-gapped computer using dfx canister sign, and another on a networked computer using dfx canister send. It is strongly recommended to take the latter approach to reduce the risk of having your private key compromised.
 +
 +
Regardless of which method you choose, you will need to download and install didc, the Candid compiler, on your networked computer. You can find the latest release here. Note that the binaries are suffixed by the operating systems they run on, didc-linux64 and didc-macos. Be sure to download the correct one. Below are commands to install didc on macos. If your’re using Linux, simply use the linux64 suffix instead.
 +
 +
<pre>
 +
$ sudo install -d /usr/local/bin
 +
$ sudo install -m 0755 ~/Downloads/didc-macos /usr/local/bin/didc
 +
</pre>
 +
 +
Regardless of which method you choose, you will also need to download and extract the NNS canister interfaces on your networked computer. You can find the latest release here. Below are commands to extract the NNS canister interfaces.
 +
 +
<pre>
 +
pushd ~/Downloads
 +
tar -f nns-ifaces-0.8.0.tar.gz -x
 +
popd
 +
</pre>
 +
 +
Additionally, you will need to have dfx.json file available in the directory from which you are running dfx commands. You can create an empty dfx.json file in your current directory by running the following command.
 +
 +
<pre>
 +
$ echo {} > dfx.json
 +
</pre>
 +
 +
Note that if you’re using an air-gapped computer, then you’ll need to repeat this step since you’ll be running dfx commands in both places.
 +
 +
After downloading and installing didc, downloading and extracting the NNS canister interfaces, and creating your dfx.json file(s), you can Claim in one step (not recommended) or Claim in two steps.
 +
 +
===Claim in one step (not recommended)===

 +
 +
Sign a message to claim your neurons.
 +
 +
Note that the time allotted to send a signed message is a fixed 5-minute window. The --expire-after option enables you to specify the point in time when the 5-minute window for sending the signed message should end. For example, if you set the --expire-after option to one hour (1h), then you must wait at least 55 minutes before you send the generated message and the signature for the message is only valid during the 5-minute window ending in the 60th minute. Hence, you would need to send the message after 55 minutes and before 60 minutes for the message to be recognized as valid. If you don’t specify the --expire-after option, then the default expiration is five minutes.
 +
 +
<pre>
 +
CANISTER=renrk-eyaaa-aaaaa-aaada-cai
 +
dfx canister --network=https://ic0.app sign --expire-after=1h $CANISTER claim_neurons '("'$PUBLIC_KEY'")'
 +
</pre>
 +
 +
The command above results in a message.json file in your current directory. You must copy that file from your air-gapped computer to your networked computer. How you do this will depend on your configuration.
 +
 +
 +
'''On your networked computer:'''
 +
 +
Verify that you can connect to the Internet Computer.
 +
 +
<pre>

 +
Send the signed message to the Genesis Token Canister to claim your neurons. As previously mentioned, you can only perform this action within the 5-minute window that you specified.
 +
 +
<pre>
 +
dfx canister --network=https://ic0.app send message.json
 +
</pre>
 +
 +
Unlike dfx canister call in the section [Claim in one step], the command dfx canister send does not return output that can be parsed by didc. Instead, it outputs only a request id.
 +
 +
In order to see the effect of your send request, you have to do an additional step. Perform the following commands on your networked machine:
 +
 +
<pre>
 +
CANISTER=renrk-eyaaa-aaaaa-aaada-cai
 +
RESULT="$(dfx canister --network=https://ic0.app call $CANISTER get_account '("paste legacy address here")' --output=raw)"
 +
didc decode -t "(Result_2)" -d ~/Downloads/nns-ifaces-0.8.0/genesis_token.did $RESULT
 +
</pre>
 +
 +
The legacy address to paste here in the second line above is what was formerly called "DFN address" in the Chrome extension. Note that the legacy address must be pasted without the 0x prefix and without the 8-character checksum at the end, i.e. it has exactly 40 characters in length. Furthermore, the legacy address must be in all lowercase. If you don’t remember it then you can obtain your legacy address by running this on your air-gapped machine:
 +
 +
<pre>
 +
$ echo $seed | keysmith legacy-address -f -
 +
</pre>
 +
 +
What you want to look for in the output of the get_account request is has_claimed = true and your principal. For example, the output of the get_account command looks like this for an unclaimed account:
 +
 +
<pre>
 +
(
 +
  variant {
 +
    Ok = record {
 +
      authenticated_principal_id = null;
 +
      successfully_transferred_neurons = vec {};
 +
      has_donated = false;
 +
      failed_transferred_neurons = vec {};
 +
      neuron_ids = vec { record { id = 1_234_567_890_123_456_789 : nat64;}; ...
 +
};
 +
      has_claimed = false;
 +
      has_forwarded = false;
 +
      icpts = 12345 : nat32;
 +
    }
 +
  },
 +
)
 +
</pre>
 +
 +
And like this for a successfully claimed account:
 +
 +
<pre>
 +
(
 +
  variant {
 +
    Ok = record {
 +
      authenticated_principal_id = opt principal "a56gn-wnhrl-i76df-ewgfe-23jfd-dfh03-ergrg-fesr1-1jhs9-reg2o-ure";
 +
      successfully_transferred_neurons = vec {};
 +
      has_donated = false;
 +
      failed_transferred_neurons = vec {};
 +
      neuron_ids = vec { record { id = 1_234_567_890_123_456_789 : nat64;}; ...
 +
};
 +
      has_claimed = true;
 +
      has_forwarded = false;
 +
      icpts = 12345 : nat32;
 +
    }
 +
  },
 +
)
 +
</pre>

==Step 3: Enable disbursal by passing the KYC process==
 +
 +
Before you can disburse ICPT from your dissolved genesis neuron you must pass KYC. Note that this applies only to genesis neurons such as the ones given to seed donors. It does not apply to neurons that you later create by staking already-liquid ICPT.
 +
 +
===Derive your DFN address===
 +
 +
The DFINITY Chrome extension generated a 12-word mnemonic seed phrase. From that seed phrase, an Ethereum-style address can be derived, which was referred to in the Chrome extension as the "DFN address". The KYC process requires that you submit your DFN address along with other information.
 +
 +
====Using Keysmith====
 +
 +
The easiest way to obtain your DFN address is to derive it from your seed phrase using Keysmith. The section Derive a native Internet Computer principal from your Ethereum seed already explained how to set up Keysmith and write your seed phrase into a file in a safe way. It is assumed here that you have carried out the steps at least up until that point. It is not important whether you have carried out any of the remaining steps on the way to claim your neurons. It is also not important whether you have installed the DFINITY Canister SDK. You only need Keysmith.
 +
 +
Derive your DFN address.
 +
 +
<pre>
 +
$ echo $seed | keysmith legacy-address -f -
 +
</pre>
 +
 +
The command above displays output similar to a typical Ethereum address, but without the leading 0x prefix, and you will use it without the 0x prefix.
 +
 +
====Using the DFINITY Chrome extension====
 +
 +
Alternatively, you may have already written down your DFN address when you ran the Chrome extension to make the donation, or taken a screenshot of it. In this case, you can use the DFN address from there and you do not have to derive it from your seed phrase. The following is to remind you where it was visible in the Chrome extension.
 +
 +
On the Chrome extension’s main page there was an information button (“i” in blue circle) next to the DFN balance:
 +
 +
[[File:dfn-chrome-extension-1.png|512px|dfn chrome extension 1]]
 +
 +
Clicking it presented a window displaying the DFN address:
 +
 +
[[File:dfn-chrome-extension-1.png|512px|dfn chrome extension 2]]
 +
 +
The DFN address displayed in the Chrome extension has a 4-byte checksum at the end and the 0x prefix. For our purposes here, you have to delete the last 8 characters and the prefix. For example: 0x98b20cae8074067c29c07a0a4ad94346cc33ee948bdcfe41 becomes 98b20cae8074067c29c07a0a4ad94346cc33ee94 which is 40 hex characters long.
 +
 +
===Derive your principal identifier===
 +
 +
The KYC form will also ask you for your principal. Derive it with Keysmith.
 +
 +
<pre>
 +
echo $seed | keysmith principal -f -
 +
</pre>
 +
 +
The command above will display your principal identifier, which should look something like this: {{code|a56gn-wnhrl-i76df-ewgfe-23jfd-dfh03-ergrg-fesr1-1jhs9-reg2o-ure}} You will be asked to enter your principal identifier on the KYC form.
 +
 +
===Submit your information===
 +
 +
To submit your information, you first go to the [https://kyc.dfinity.org/gtc KYC landing page]. The landing page is a frontend hosted by the DFINITY Foundation and any information entered here is not shared with the external KYC provider.
 +
 +
If the DFN address is valid, you are forwarded to the KYC main page.
 +
 +
If you are not forwarded and instead see "Address not found" then your DFN address is invalid. Please double-check the address. For troubleshooting, see the subsection below.
 +
 +
Once you are on the KYC main page, you can submit your personal identifying information (PII). Information entered on this page will be sent directly to the KYC provider.
 +
 +
===Troubleshooting===
 +
 +
If you have problems with your DFN address, then you can verify it using [https://etherscan.io/address/0x1Be116204bb55CB61c821a1C7866fA6f94b561a5#readContract Etherscan].
 +
 +
After you connect to Etherscan, scroll down to row “51. tokens”, open the dropdown form by expanding the row, paste your DFN address in the field “<input> (address)” and click “Query”. For the example address 2d89d96b10f7a9456a9154b2f5309ee70df5bce1 you will see:
 +
 +
[File:Etherscan-FDC-query.png|512px|Etherscan]
 +
 +
If you made a seed donation then you will see the token amount that the FDC calculated. If the DFN address is incorrect then it will show a token amount of 0.
  
 
==Step 4: Instruct the neurons you wish to unstake to dissolve==
 
==Step 4: Instruct the neurons you wish to unstake to dissolve==
 +
 +
Once you have claimed your neurons and completed the KYC process, you can start "dissolving" your neurons.
 +
 +
YOU ARE HIGHLY ENCOURAGED TO READ [https://medium.com/dfinity/understanding-the-internet-computers-network-nervous-system-neurons-and-icp-utility-tokens-730dab65cae8 THIS BLOG POST] BEFORE YOU START DISSOLVING YOUR NEURONS. THERE ARE MANY BENEFITS TO NEURON OWNERSHIP. BE SURE YOU UNDERSTAND EXACTLY WHAT YOU ARE GIVING UP BY DISSOLVING THEM. IN PARTICULAR, YOUR NEURONS A PRE-AGED AT 18-MONTHS, MEANING THAT YOUR VOTING REWARDS RECEIVE A MULTIPLIER EFFECT, WHICH YOU WILL LOSE WHEN YOUR NEURONS ENTER THE DISSOLVE STATE.
 +
 +
Dissolving a neuron is not instantaneous, but rather takes place over a period of time known as the "dissolve delay". The dissolve delay is a parameter of the individual neuron. In general, different neurons have different dissolve delays. When a neuron is dissolving, its dissolve delay falls over the passage of time, until either it is stopped by you, or it reaches zero. Once the dissolve delay reaches zero, it stops falling, and only then can you instruct the neuron to disburse your ICP tokens.
 +
 +
Your neurons have dissolve delays of 0,1,2,…​,30 or 48 months.
 +
 +
To start the dissolution of one of your neurons, you must sign and send a message to the governance canister. You can accomplish this in one step on a networked computer using dfx canister call, or as two separate steps, one on an air-gapped computer using dfx canister sign, and another on a networked computer using dfx canister send. It is strongly recommended to take the latter approach to reduce the risk of having your private key compromised.

Introduction

Steps to configure a neuron using the DFINITY Canistr SDK.

Warning

This process is not currently possible on macOS computers with M1 chips. You can only install the DFINITY Canister SDK dfx and the Candid compiler didc on Intel-based macOS and Linux computers.

Step 1: Derive a native Internet Computer principal from your Ethereum seed

As an early contributor or seed donor, you wrote down a 12-word mnemonic seed phrase that was generated by the DFINITY Chrome extension. To create an identity, you must derive a private key from your seed phrase and import that private key into the DFINITY Canister SDK. This step is required before you can Take control of your neurons.

Step 1a: Secure your environment

The safety and security of your private key is your responsibility and there is no substitute for planning ahead, bringing the right equipment, having the right skills, and using good judgment. It is strongly recommended that you proceed using an air-gapped computer to reduce the risk of having your private key compromised. Depending on the hardware available, you might want to physically remove your network controller, microphone, speakers, and other components, or disable them in your BIOS. Covert channels can be established through a variety of different mediums, including sound, light, radio-frequency, and physical media. Be sure to evaluate the capabilities of your system before settling on a configuration that makes sense for you. If you don’t know what you are doing, you should consult with a computer security expert. Do not contact the DFINITY Foundation for help with securing your environment.

Step 1b: Install Keysmith

You need Keysmith to derive your private/public key pair from the seed phrase.

To install Keysmith, there are two options:

a. Fetch the release binary

b. Build Keysmith from source.

Option A: Fetch the release binary

If you want to download the Keysmith release binary, keep in mind that you must perform this action on a computer with a network connection. If you are using an air-gapped computer, then you must copy the release binary from your networked computer to your air-gapped computer. How you do this will depend on your configuration.

To download the Keysmith release binary, fetch release v1.5.0 from Github.

Keysmith supports the following operating systems and architectures:

  • Darwin / AMD64 – for macOS models with an Intel chip ([how to check])
  • Darwin / ARM64 – for newer macOS models with an M1 chip ([how to check])
  • Linux / AMD64
  • Linux / ARM32
  • Linux / ARM64
  • Windows / AMD64

Download the .tar.gz file matching your architecture and operating system. If you have a newer M1-based macOS, download keysmith-darwin-arm64.tar.gz. Although you can install keysmith on macOS computers with an M1 chip, you can only install the DFINITY Canister SDK dfx command-line interface on Intel-based macOS computers. For an Intel-based macOS, download keysmith-darwin-amd64.tar.gz.

Verify the SHA256 checksum of your download

Open a terminal and change to the download directory. On a Mac this is 

$ cd ~/Downloads

Compute the SHA256 checksum of your download. 

$ openssl dgst -sha256 keysmith-*.tar*

Make sure the output matches one of the following lines: 

SHA256(keysmith-darwin-amd64.tar.gz)= ad7383d60bced19580fa37b77e133b1e80416b482e4c5326ac2fd17a7710a318
SHA256(keysmith-darwin-arm64.tar.gz)= da1a4ac5ae04b85d4c5b0a3deb6442fb7c456dcf97cbd6ff8153316c5dbb29a9
SHA256(keysmith-linux-amd64.tar.gz)= 7901c3a23aef298f930d1dddf8eee23bc51a55ffda670accfd7b9e37748913d8

If your browser already unzipped the .tar.gz for you and you have a file ending in .tar then make sure the output of openssl matches one of the following lines: 

SHA256(keysmith-darwin-amd64.tar)= 97b8048f00e75d6adc8651aac1aa77d9bd9c150b0dbc0b0f6409f0d6bdbb24a4

Unpack and install keysmith

To extract the executable from the tarball, enter the following command into your terminal: 

$ tar -f keysmith-*.tar* -x

Next, add the executable to your PATH by entering the commands below: 

$sudo install -d /usr/local/bin
$sudo install keysmith /usr/local/bin

You will be prompted to enter your laptop password. The password itself will not appear, simply type it and press enter.

Run it

$ keysmith

You should see: 

usage: keysmith <command> [<args>]

Available Commands:
    account             Print your account identifier.
    generate            Generate your mnemonic seed.
    legacy-address      Print your legacy address.
    principal           Print your principal identifier.
    private-key         Write your private key to a file.
    public-key          Print your public key.
    version             Print the version number.
    x-public-key        Print your extended public key.

If you are using macOS, making the keysmith binary executable might require you to change a permission setting using System Preferences > Security & Privacy > General.

Option B: Build Keysmith from source

f you want to build the Keysmith from source, keep in mind that you must perform this action on a computer with a network connection. If you are using an air-gapped computer, then you must copy the target binary from your networked computer to your air-gapped computer. How you do this will depend on your configuration.

Keysmith is written in Go, so if you choose to build it from source, then you must first download and install Go, verify that go is in your PATH, and configure your GOPATH and GOBIN environment variables.

Run the following command to build Keysmith from source. 

$ go get github.com/dfinity/keysmith

Step 1c: Install the DFINITY Canister SDK

You can install the DFINITY Canister SDK by fetching the v0.7.0 release binary from our website. It is not yet possible to build the DFINITY Canister SDK from source. Note that this action can only be performed on a networked computer. If you are using an air-gapped computer, then you must copy the release binary from your networked computer to your air-gapped computer. How you do this will depend on your configuration.

Run the following command to install the DFINITY Canister SDK. 

$ sh -ci "$(curl -fsSL https://sdk.dfinity.org/install.sh)"

Warning: Note that dfx will currently not install on M1-based Macs.

Step 1d: Set your seed phrase for use with keysmith

Once you have installed Keysmith and the DFINITY Canister SDK, and you are confident that your environment is secure, then you are ready to enter your seed for use with keysmith. For the duration of your session, you store your seed phrase in an environment variable. It will be eliminated from your system when you turn your computer off. 

$ read seed

Enter your seed phrase and finish with Return.

If you prefer to not have your seed phrase displayed as you type then use this command instead: 

$ read -s seed

Step 1e: Check your legacy address and balance (optional)

At this point you can already verify your legacy address and ICPT balance. The legacy address matches to what was formerly called "DFN address" in the Dfinity Chrome extension. You may have copied it from the Chrome extension for your records back when you used the extension. 

echo $seed | keysmith legacy-address -f -

The output is a 40 character hex string. It looks something like this: 

2d89d96b10f7a9456a9154b2f5309ee70df5bce1

You can check your ICPT balance as follows: 

echo {} > dfx.json
GTC=renrk-eyaaa-aaaaa-aaada-cai
ADDR=$(echo $seed | keysmith legacy-address -f -)
dfx canister --network=https://ic0.app call $GTC balance '("'$ADDR'")'

The output is the number of ICPT associated with your address.

If you are an early contributor then you may have multiple addresses, all derived from your one seed phrase. To check the balance in each of them you do the following commands: 

GTC=renrk-eyaaa-aaaaa-aaada-cai
ADDR=$(echo $seed | keysmith legacy-address -f - -i 0)
dfx canister --network=https://ic0.app call $GTC balance '("'$ADDR'")'

Then you repeat the last two lines with -i 1, -i 2, etc.

Step 1f: Derive and import your private key

Derive your private key from your seed phrase. 

$ echo $seed | keysmith private-key -f -


This creates a file identity.pem containing your private key. Import your private key(s) into the DFINITY Canister SDK and then remove it from the filesystem. 

$ dfx identity import <name> identity.pem
$ rm identity.pem


Here, <name> is an alias that you can choose arbitrarily for your identity, e.g. "jane". The command above displays output similar to the following: 

Creating identity: "jane".
Created identity: "jane".

Make your new identity the currently-active one. 

$ dfx identity use <name>

The command above displays output similar to the following: 

Using identity: "jane".

At any time, you can list all available identities with 

$ dfx identity list

Step 2: Take control of your neurons

You will receive your tokens inside a set of neurons that have been pre-created for you. The number of neurons will total 31 or 49 depending on whether you are an early contributor or seed donor, respectively. Your tokens are disbursed equally over these neurons. Claiming your neurons is the process of obtaining control over your neurons. It is done for all neurons at once.

Your neurons differ by their dissolve delay. For an explanation of dissolve delay see Instruct the neurons you wish to unstake to dissolve below.

To claim your neurons, you need to sign and send a message to the Genesis Token Canister. You can accomplish this in one step on a networked computer using dfx canister call, or as two separate steps, one on an air-gapped computer using dfx canister sign, and another on a networked computer using dfx canister send. It is strongly recommended to take the latter approach to reduce the risk of having your private key compromised.

Regardless of which method you choose, you will need to download and install didc, the Candid compiler, on your networked computer. You can find the latest release here. Note that the binaries are suffixed by the operating systems they run on, didc-linux64 and didc-macos. Be sure to download the correct one. Below are commands to install didc on macos. If your’re using Linux, simply use the linux64 suffix instead. 

$ sudo install -d /usr/local/bin
$ sudo install -m 0755 ~/Downloads/didc-macos /usr/local/bin/didc

Regardless of which method you choose, you will also need to download and extract the NNS canister interfaces on your networked computer. You can find the latest release here. Below are commands to extract the NNS canister interfaces. 

pushd ~/Downloads
tar -f nns-ifaces-0.8.0.tar.gz -x
popd

Additionally, you will need to have dfx.json file available in the directory from which you are running dfx commands. You can create an empty dfx.json file in your current directory by running the following command. 

$ echo {} > dfx.json

Note that if you’re using an air-gapped computer, then you’ll need to repeat this step since you’ll be running dfx commands in both places.

After downloading and installing didc, downloading and extracting the NNS canister interfaces, and creating your dfx.json file(s), you can Claim in one step (not recommended) or Claim in two steps.

Claim in one step (not recommended)

Verify that you can connect to the Internet Computer. 

$ dfx ping https://ic0.app

Derive your public key. 

$ PUBLIC_KEY="$(echo $seed | keysmith public-key -f -)"

Call the Genesis Token Canister to claim your neurons. 

CANISTER=renrk-eyaaa-aaaaa-aaada-cai
RESULT="$(dfx canister --network=https://ic0.app call $CANISTER claim_neurons '("'$PUBLIC_KEY'")' --output=raw)"
didc decode -t "(Result)" -d ~/Downloads/nns-ifaces-0.8.0/genesis_token.did $RESULT

Claim in two steps

On your air-gapped computer:

Derive your public key.

PUBLIC_KEY="$(echo $seed | keysmith public-key -f -)"

Sign a message to claim your neurons.

Note that the time allotted to send a signed message is a fixed 5-minute window. The --expire-after option enables you to specify the point in time when the 5-minute window for sending the signed message should end. For example, if you set the --expire-after option to one hour (1h), then you must wait at least 55 minutes before you send the generated message and the signature for the message is only valid during the 5-minute window ending in the 60th minute. Hence, you would need to send the message after 55 minutes and before 60 minutes for the message to be recognized as valid. If you don’t specify the --expire-after option, then the default expiration is five minutes. 

CANISTER=renrk-eyaaa-aaaaa-aaada-cai
dfx canister --network=https://ic0.app sign --expire-after=1h $CANISTER claim_neurons '("'$PUBLIC_KEY'")'

The command above results in a message.json file in your current directory. You must copy that file from your air-gapped computer to your networked computer. How you do this will depend on your configuration.


On your networked computer:

Verify that you can connect to the Internet Computer. 

$ dfx ping https://ic0.app

copy Send the signed message to the Genesis Token Canister to claim your neurons. As previously mentioned, you can only perform this action within the 5-minute window that you specified. 

dfx canister --network=https://ic0.app send message.json

Unlike dfx canister call in the section [Claim in one step], the command dfx canister send does not return output that can be parsed by didc. Instead, it outputs only a request id.

In order to see the effect of your send request, you have to do an additional step. Perform the following commands on your networked machine: 

CANISTER=renrk-eyaaa-aaaaa-aaada-cai
RESULT="$(dfx canister --network=https://ic0.app call $CANISTER get_account '("paste legacy address here")' --output=raw)"
didc decode -t "(Result_2)" -d ~/Downloads/nns-ifaces-0.8.0/genesis_token.did $RESULT

The legacy address to paste here in the second line above is what was formerly called "DFN address" in the Chrome extension. Note that the legacy address must be pasted without the 0x prefix and without the 8-character checksum at the end, i.e. it has exactly 40 characters in length. Furthermore, the legacy address must be in all lowercase. If you don’t remember it then you can obtain your legacy address by running this on your air-gapped machine: 

$ echo $seed | keysmith legacy-address -f -

What you want to look for in the output of the get_account request is has_claimed = true and your principal. For example, the output of the get_account command looks like this for an unclaimed account: 

(
  variant {
    Ok = record {
      authenticated_principal_id = null;
      successfully_transferred_neurons = vec {};
      has_donated = false;
      failed_transferred_neurons = vec {};
      neuron_ids = vec { record { id = 1_234_567_890_123_456_789 : nat64;}; ...
		};
      has_claimed = false;
      has_forwarded = false;
      icpts = 12345 : nat32;
    }
  },
)

And like this for a successfully claimed account: 

(
  variant {
    Ok = record {
      authenticated_principal_id = opt principal "a56gn-wnhrl-i76df-ewgfe-23jfd-dfh03-ergrg-fesr1-1jhs9-reg2o-ure";
      successfully_transferred_neurons = vec {};
      has_donated = false;
      failed_transferred_neurons = vec {};
      neuron_ids = vec { record { id = 1_234_567_890_123_456_789 : nat64;}; ...
		};
      has_claimed = true;
      has_forwarded = false;
      icpts = 12345 : nat32;
    }
  },
)

Step 3: Enable disbursal by passing the KYC process

Before you can disburse ICPT from your dissolved genesis neuron you must pass KYC. Note that this applies only to genesis neurons such as the ones given to seed donors. It does not apply to neurons that you later create by staking already-liquid ICPT.

Derive your DFN address

The DFINITY Chrome extension generated a 12-word mnemonic seed phrase. From that seed phrase, an Ethereum-style address can be derived, which was referred to in the Chrome extension as the "DFN address". The KYC process requires that you submit your DFN address along with other information.

Using Keysmith

The easiest way to obtain your DFN address is to derive it from your seed phrase using Keysmith. The section Derive a native Internet Computer principal from your Ethereum seed already explained how to set up Keysmith and write your seed phrase into a file in a safe way. It is assumed here that you have carried out the steps at least up until that point. It is not important whether you have carried out any of the remaining steps on the way to claim your neurons. It is also not important whether you have installed the DFINITY Canister SDK. You only need Keysmith.

Derive your DFN address. 

$ echo $seed | keysmith legacy-address -f -

The command above displays output similar to a typical Ethereum address, but without the leading 0x prefix, and you will use it without the 0x prefix.

Using the DFINITY Chrome extension

Alternatively, you may have already written down your DFN address when you ran the Chrome extension to make the donation, or taken a screenshot of it. In this case, you can use the DFN address from there and you do not have to derive it from your seed phrase. The following is to remind you where it was visible in the Chrome extension.

On the Chrome extension’s main page there was an information button (“i” in blue circle) next to the DFN balance:

dfn chrome extension 1

Clicking it presented a window displaying the DFN address:

dfn chrome extension 2

The DFN address displayed in the Chrome extension has a 4-byte checksum at the end and the 0x prefix. For our purposes here, you have to delete the last 8 characters and the prefix. For example: 0x98b20cae8074067c29c07a0a4ad94346cc33ee948bdcfe41 becomes 98b20cae8074067c29c07a0a4ad94346cc33ee94 which is 40 hex characters long.

Derive your principal identifier

The KYC form will also ask you for your principal. Derive it with Keysmith. 

echo $seed | keysmith principal -f -

The command above will display your principal identifier, which should look something like this: a56gn-wnhrl-i76df-ewgfe-23jfd-dfh03-ergrg-fesr1-1jhs9-reg2o-ure You will be asked to enter your principal identifier on the KYC form.

Submit your information

To submit your information, you first go to the KYC landing page. The landing page is a frontend hosted by the DFINITY Foundation and any information entered here is not shared with the external KYC provider.

If the DFN address is valid, you are forwarded to the KYC main page.

If you are not forwarded and instead see "Address not found" then your DFN address is invalid. Please double-check the address. For troubleshooting, see the subsection below.

Once you are on the KYC main page, you can submit your personal identifying information (PII). Information entered on this page will be sent directly to the KYC provider.

Troubleshooting

If you have problems with your DFN address, then you can verify it using Etherscan.

After you connect to Etherscan, scroll down to row “51. tokens”, open the dropdown form by expanding the row, paste your DFN address in the field “<input> (address)” and click “Query”. For the example address 2d89d96b10f7a9456a9154b2f5309ee70df5bce1 you will see:

[File:Etherscan-FDC-query.png|512px|Etherscan]

If you made a seed donation then you will see the token amount that the FDC calculated. If the DFN address is incorrect then it will show a token amount of 0.

Step 4: Instruct the neurons you wish to unstake to dissolve

Once you have claimed your neurons and completed the KYC process, you can start "dissolving" your neurons.

YOU ARE HIGHLY ENCOURAGED TO READ THIS BLOG POST BEFORE YOU START DISSOLVING YOUR NEURONS. THERE ARE MANY BENEFITS TO NEURON OWNERSHIP. BE SURE YOU UNDERSTAND EXACTLY WHAT YOU ARE GIVING UP BY DISSOLVING THEM. IN PARTICULAR, YOUR NEURONS A PRE-AGED AT 18-MONTHS, MEANING THAT YOUR VOTING REWARDS RECEIVE A MULTIPLIER EFFECT, WHICH YOU WILL LOSE WHEN YOUR NEURONS ENTER THE DISSOLVE STATE.

Dissolving a neuron is not instantaneous, but rather takes place over a period of time known as the "dissolve delay". The dissolve delay is a parameter of the individual neuron. In general, different neurons have different dissolve delays. When a neuron is dissolving, its dissolve delay falls over the passage of time, until either it is stopped by you, or it reaches zero. Once the dissolve delay reaches zero, it stops falling, and only then can you instruct the neuron to disburse your ICP tokens.

Your neurons have dissolve delays of 0,1,2,…​,30 or 48 months.

To start the dissolution of one of your neurons, you must sign and send a message to the governance canister. You can accomplish this in one step on a networked computer using dfx canister call, or as two separate steps, one on an air-gapped computer using dfx canister sign, and another on a networked computer using dfx canister send. It is strongly recommended to take the latter approach to reduce the risk of having your private key compromised.

Dissolve in one step (not recommended)

Verify that you can connect to the Internet Computer. 

$ dfx ping https://ic0.app

Recall the identifier of the neuron you want to dissolve and declare it as an environment variable. 

NEURON_ID=...

Call the governance canister to dissolve your neuron. 

CANISTER=rrkah-fqaaa-aaaaa-aaaaq-cai
RESULT="$(dfx canister --network=https://ic0.app call $CANISTER manage_neuron "(record { id = opt record { id = $NEURON_ID:nat64 }; command = opt variant { Configure = record { operation = opt variant { StartDissolving = record {} } } } })" --output=raw)"
didc decode -t "(ManageNeuronResponse)" -d ~/Downloads/nns-ifaces-0.8.0/governance.did $RESULT

Note that if you want to dissolve all of your neurons, then you must repeat the step above for each neuron identifier.

Dissolve in two steps

On your air-gapped computer

Recall the identifier of the neuron you want to dissolve and declare it as an environment variable. 

NEURON_ID=...

Sign a message to dissolve your neurons.

Recall the behavior of the --expire-after option to ensure that you deliver the message within the correct 5-minute window. 

CANISTER=rrkah-fqaaa-aaaaa-aaaaq-cai
dfx canister --network=https://ic0.app sign --expire-after=1h $CANISTER manage_neuron "(record { id = opt record { id = $NEURON_ID:nat64 }; command = opt variant { Configure = record { operation = opt variant { StartDissolving = record {} } } } })"

The command above results in a message.json file in your current directory. You must copy that file from your air-gapped computer to your networked computer. How you do this will depend on your configuration.

On your networked computer

Verify that you can connect to the Internet Computer. 

$ dfx ping https://ic0.app

Send the signed message to the governance canister to dissolve your neurons. As previously mentioned, you can only perform this action within the 5-minute window that you specified. 

$ dfx canister --network=https://ic0.app send message.json

Step 5: Disburse ICP from neurons that are fully dissolved

Disburse in one step (not recommended)

Verify that you can connect to the Internet Computer. 

dfx ping https://ic0.app

Recall your account identifier and declare it as an environment variable. 

ACCOUNT_ID=$(echo $seed | keysmith account -f -)

Recall the identifier of the neuron you want to dissolve and declare it as an environment variable. 

NEURON_ID=...

Disburse the ICP tokens locked in your neuron. 

CANISTER=rrkah-fqaaa-aaaaa-aaaaq-cai
ACCOUNT_ID_WITHOUT_CHECKSUM_BYTES="$(printf ${ACCOUNT_ID:8} | fold -w 2 | xargs -I {} printf '%d:nat8; ' '0x{}')"
RESULT="$(dfx canister --network=https://ic0.app call $CANISTER manage_neuron "(record { id = opt record { id = $NEURON_ID:nat64 }; command = opt variant { Disburse = record { to_account = opt record { hash = vec { $ACCOUNT_ID_WITHOUT_CHECKSUM_BYTES } }; amount = null } } })" --output=raw)"
didc decode -t "(ManageNeuronResponse)" -d ~/Downloads/nns-ifaces-0.8.0/governance.did $RESULT

Disburse in two steps

On your air-gapped computer

Recall your account identifier and declare it as an environment variable. 

ACCOUNT_ID=$(echo $seed | keysmith account -f -)

Recall the identifier of the neuron you want to dissolve and declare it as an environment variable. 

NEURON_ID=...

Sign a message to disburse the ICP tokens locked your neuron.

Recall the behavior of the --expire-after option to ensure you that you deliver the message within the correct 5-minute window. 

CANISTER=rrkah-fqaaa-aaaaa-aaaaq-cai
ACCOUNT_ID_WITHOUT_CHECKSUM_BYTES="$(printf ${ACCOUNT_ID:8} | fold -w 2 | xargs -I {} printf '%d:nat8; ' '0x{}')"
dfx canister --network=https://ic0.app sign --expire-after=1h $CANISTER manage_neuron "(record { id = opt record { id = $NEURON_ID:nat64 }; command = opt variant { Disburse = record { to_account = opt record { hash = vec { $ACCOUNT_ID_WITHOUT_CHECKSUM_BYTES } }; amount = null } } })"

The command above results in a message.json file in your current directory. You must copy that file from your air-gapped computer to your networked computer. How you do this will depend on your configuration.

On your networked computer

Verify that you can connect to the Internet Computer. 

$ dfx ping https://ic0.app


Send the signed message to the governance canister to disburse the ICP tokens locked your neuron. As previously mentioned, you can only perform this action within the 5-minute window that you specified. 

dfx canister --network=https://ic0.app send message.json
