Currently, only USDC can be deposited and used as collateral. You can deposit funds to open a position and satisfy margin requirements or replenish your margin level to maintain an existing position.
To deposit USDC from an outside source into your International Exchange account:
Navigate to Portfolio in the left navigation bar of the screen and select Deposit
Select USD Coin (USDC is currently the only currency we allow for deposits and withdrawals)
Select Crypto Address and follow the instructions by going to your wallet or exchange and send USDC to the displayed Coinbase International Exchange wallet address
Please note that only USDC deposits on the Ethereum network are enabled on the International Exchange.
There are no fees for off-chain transfers between your Exchange and International Exchange accounts. These transfers are processed instantaneously.
