Every account has one deposit wallet on Base. Send USDC to it, then call Create Transfer with from: "deposit" and to: "<venue>" to fund a specific venue. To deposit from another chain, use Quote Transfer with from: "external" - the response includes a signed transaction your end user submits from their own wallet. The response includes the current balance - USDC sitting at the deposit wallet specifically. It does not include funds held at any venue trading wallet. Use it to confirm an inbound deposit landed before routing the funds to a venue via POST /transfers.
The deposit wallet is the canonical entry point for every venue except Hyperliquid, which is funded via Across - see Funding & Withdrawals.
