Deposit

Read GET /collateral/wallets and use the wallet whose asset and chain match your transfer. Vantage currently uses native USDC on Base for the USDC collateral flow.
A token with the same symbol on another network does not fund the Base position.

Reconcile

Poll GET /collateral/deposits until the transaction has the required confirmations and status confirmed. Then read GET /collateral/position for the updated value, borrowing capacity, LTV, and price timestamp. Ledger balances reflect confirmed credits less releases and seizures. They are not a raw wallet balance.

Return address

GET /collateral/withdrawal-addresses returns approved and pending destinations. Submit changes in the dashboard. Vantage requires operator approval before an address can receive a payout or collateral return. Keep the approved address active until the return transaction is final.
