ckUSDC Transactions
Chain-key USDC (ckUSDC), a multi-chain USDC twin on the Internet Computer, is an ICRC-1-compliant token that is backed 1:1 by USDC such that 1 ckUSDC can always be redeemed for 1 USDC and vice versa. The ckETH minter canister is responsible for both minting ckUSDC tokens when users transfer USDC to its control and burning ckUSDC when handling USDC retrieval requests. ckUSDC transactions are facilitated through a ledger canister, which in conjunction with archive canisters, tracks ckUSDC account balances and transaction history between accounts. An index canister provides access to ckUSDC transactions associated with individual accounts.
