Funding your ErisX spot account may be quicker with USDC.  As USDC operates on the Ethereum blockchain the same number of confirmations as for ETH deposits applies.  Please refer to our Blockchain Confirmations schedule to check how many confirmations are currently required. The cost of funding your account may be lower based upon the fees it would cost for Wire transfer vs blockchain fees. The ErisX restrictions for ACH deposits of USD are not applicable to deposits and withdrawals of USDC.  This includes the deposit limits and the hold times for withdrawals.
