Bridge USDT from Optimism to Ethereum

Open the transfer interface at usdt0.to/transfer and connect any EVM wallet. Pick Optimism as the origin and Ethereum as the destination, enter the amount, then approve the transaction in your wallet. The transfer usually completes in about 33m 56s, depending on Optimism finality.

There is no protocol fee: USDT0 takes no cut of the amount. You pay network gas on Optimism and the LayerZero messaging fee that carries the transfer, both quoted in the interface before you confirm.

Yes. Ethereum holds the asset itself, so the matching USDT is released from its lockbox as the transfer arrives. It is the same USDT you would hold natively on Ethereum, with no wrapped or synthetic version involved.

Transfers are secured by LayerZero, the interoperability protocol behind USDT0, and by the USDT0 Attestation System, which verifies every transfer through independent attestation before it finalizes. Each message needs sign-off from the Core Attestation Set, a 3-of-3 signer group of USDT0, LayerZero, and Canary, so no single verifier can approve a transfer on its own. On this pair USDT moves with a burn-and-unlock model and 1:1 backing: no wrapped tokens, no external bridges.
