Swap OP to USDT in three steps without creating an account. You see an estimated amount before you send, the exchange runs automatically once your deposit confirms, and the USDT goes straight to the wallet address you enter.
Enter the amount of Optimism you want to swap in the widget above. It shows an estimate of the Tether (ERC20) you will receive on the Ethereum network at the current floating rate, with the payout network fee already taken into account.
Paste your USDT wallet address and check it twice, because blockchain transfers cannot be reversed. If the coin needs a memo or destination tag, a field for it appears. xswap.to never asks for your private keys.
Confirm the order and send your OP to the one-time deposit address on the OP Mainnet (Optimism) network. Once the deposit confirms, the swap runs automatically and the USDT is sent to your wallet. The order page shows every stage.
Swapping Optimism (OP) for Tether (ERC20) (USDT) here takes one transfer from your wallet: no exchange account, no balance to deposit and no withdrawal queue. You choose the receiving address, and the USDT goes there once the swap completes.
Rates are floating, so the amount shown is an estimate that can shift slightly while your Optimism deposit confirms on OP Mainnet (Optimism). The payout is sent on Ethereum, so check that your Tether (ERC20) address belongs to that network before you confirm.
Refreshed hourly. The widget shows the live estimate.
34 OP
≈
1.845799 USDT
At the latest hourly update, 34 OP converts to about 1.845799 USDT. The figure comes from the floating rate and already allows for the payout network fee. Rates move, so the widget recalculates the estimate when you enter your own amount, and no account or registration is needed to swap.
