Examples

The quill ckbtc update-balance command is used to convert already-deposited BTC into ckBTC:

# After transferring BTC:
quill ckbtc update-balance

This will return a response like:

(
    variant {
        Ok = vec {
            variant {
                Minted = record {
                    block_index = 5_581_035 : nat64;
                    minted_amount = 4_000_000 : nat64;
                    utxo = record { ... };
                }
            }
        }
    }
)

The provided block index can be looked up on the BIG dashboard.

The returned amount is the number of satoshis, or hundred-millionths of a ckBTC; in this case the user would have minted 0.04 ckBTC.

Remarks

The --sender flag is required if a signing key is not provided.

As this is an update call, it will not actually make the request, but rather generate a signed and packaged request that can be sent from anywhere. You can use the --qr flag to display it as a QR code, or if you are not working with an air-gapped machine, you can pipe it to quill send.
