Onchain settlement

How USDC moves into custody and back to your wallet.

Custody

All USDC on the exchange sits in one custody contract. Trading runs on the private ledger and never waits on the chain; balances settle onchain as net totals that carry no position, order, or fill. Custody is a contract only the owner’s signature can withdraw from: every withdrawal pays to the wallet of the owner who signed it and no agent, relayer, or operator can redirect it.

Deposits and withdrawals

Deposits are native USDC, including USDC sent from other chains in one transaction, with no fee or minimum. A withdrawal of USDC or SUB to your wallet costs 1 USDC.
