Swapping USDT — FAQ
How do I swap USDT on Optimism?
Connect a wallet, keep USDT as the token you want, enter an amount, and review the best route. SwapRoute compares live quotes from numerous aggregators and shows route details and the minimum received before you sign — no account needed.
What's the best rate to swap USDT?
SwapRoute doesn't rely on a single venue. It queries every capable provider at once and ranks routes by the net amount you'd actually receive, so the best available USDT rate is shown first. Rates move with the market, so the quote refreshes as you type.
Can I buy USDT with ETH or a stablecoin?
Yes. Pay with ETH, USDC, USDT or another token you already hold and route to USDT. If your input is on a different chain, SwapRoute finds a cross-chain route automatically.
Is USDT available on other chains?
USDT is routable on 10 of SwapRoute's supported chains. You can swap into USDT on Optimism here, or open the USDT page for another network from the links below.
Does SwapRoute hold my USDT?
No. SwapRoute is a non-custodial routing interface. You connect your own wallet, review the transaction, and sign directly — your USDT never touches our servers and we never hold your keys.
