ETH to USDT FAQ
Do I need to connect a Base wallet?
No. The exchange issues a deposit address on Base and you send ETH to it from Coinbase Wallet, MetaMask, Rabby, Ledger or an exchange withdrawal. Nothing is signed in the browser.
How long does ETH on Base to USDT on Optimism take?
Usually a few minutes from the moment your ETH deposit confirms. The quote shows an ETA for this exact route before you send anything.
Which OP Mainnet address can receive the USDT?
Any OP Mainnet address, a standard 0x… EVM address. OP Mainnet shares your Ethereum address. If you pay out to an exchange, confirm it accepts Optimism deposits for this asset.
Do I need ETH on Optimism to receive USDT?
No. Receiving a token costs the recipient nothing. You only need ETH later, when you move the USDT out of that address.
What happens if the swap fails after I send ETH?
The ETH is refunded on Base and the order page shows the refund status. A failed route does not leave funds stuck halfway.
