Bridge XAUT from Celo to Arbitrum

Open the transfer interface at usdt0.to/transfer and connect any EVM wallet. Pick Celo as the origin and Arbitrum as the destination, enter the amount, then approve the transaction in your wallet. The transfer usually completes in about 41m 52s, depending on Celo finality.

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

XAUT0 on Arbitrum is the XAUT0 representation of XAUT within the USDT0 Network. It keeps one unified XAUT across supported chains instead of a separate bridged version with isolated liquidity, and stays backed 1:1 by XAUT held in reserve. On Arbitrum it works as the XAUT 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 XAUT moves with a burn-and-mint model and 1:1 backing: no wrapped tokens, no external bridges.
