Bridge USDT from Arbitrum to Mantle

Open the transfer interface at usdt0.to/transfer and connect any EVM wallet. Pick Arbitrum as the origin and Mantle as the destination, enter the amount, then approve the transaction in your wallet. The transfer usually completes in about 22m 40s, depending on Arbitrum finality.

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

USDT0 on Mantle is the USDT0 representation of USDT within the USDT0 Network. It keeps one unified USDT across supported chains instead of a separate bridged version with isolated liquidity, and stays backed 1:1 by USDT held in reserve. On Mantle it works as the USDT asset available through USDT0.

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-mint model and 1:1 backing: no wrapped tokens, no external bridges.
