View source for Topping up canisters

= Using dfx =
There are two options to top up any canister: By depositing cycles, or by converting ICP to cycles directly.

== Depositing cycles ==

If you have a cycles wallet configured, you can take any amount of cycles from it and deposit them directly into a canister. To do so, use
    dfx canister --network ic deposit-cycles <canister id> <amount of cycles>

As an example, to send 10 trillion cycles (TC) to canister <code>fg7gi-vyaaa-aaaal-qadca-cai</code>, you would run
    dfx canister --network ic deposit-cycles fg7gi-vyaaa-aaaal-qadca-cai 10000000000000

== Using ICP directly ==

If you have ICP that you want to use to top up any canister, you can run
    dfx ledger --network ic top-up <canister id> --amount <amount of ICP to convert>

As an example, to top up canister <code>fg7gi-vyaaa-aaaal-qadca-cai</code> with 10.3 ICP, you can run
    dfx ledger --network ic top-up fg7gi-vyaaa-aaaal-qadca-cai --amount 10.3
