Tether, on Arbitrum

USDT0 on Arbitrum 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. For users on Arbitrum, USDT0 works as the USDT asset available through the USDT0 system.

Transfers to and from Arbitrum are secured by LayerZero, the interoperability protocol behind USDT0, and by the USDT0 Attestation System. The Attestation System 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. No single verifier can approve a transfer on its own. USDT0 moves with a burn-and-mint model and 1:1 backing: no wrapped tokens, no external bridges.

Moving USDT0 between Arbitrum and any other USDT0 Network chain has no protocol fee (0 bps). You only pay network gas on the source and destination chains. When the other side is a Legacy Mesh chain (native USDT on Solana, TON, Tron, and Celo), the transfer routes through the Legacy Mesh and costs 0.03% (3 bps), paid in USDT.
