Tether Gold, on BNB Chain

XAUT0 on BNB Chain is the XAUT0 representation of Tether Gold (XAUT) within the USDT0 Network. It keeps one unified Tether Gold across supported chains instead of a separate bridged version with isolated liquidity. For users on BNB Chain, XAUT0 works as the Tether Gold asset available through the USDT0 system.

Transfers to and from BNB Chain 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. XAUT0 moves with a burn-and-mint model and 1:1 backing: no wrapped tokens, no external bridges.

Bridging XAUT0 to and from BNB Chain has no protocol fee (0 bps) because it is an in-network transfer on the USDT0 Network. You only pay network gas on the source and destination chains.

The BNB Chain XAUT contract address is 0x21cAef8A43163Eea865baeE23b9C2E327696A3bf. This is the contract for the Tether Gold token you receive when you bridge XAUT to BNB Chain through USDT0. Double-check the full address before sending funds.

On BNB Chain, the USDT0 transfer widget supports MetaMask, Rabby, and other EVM browser wallets, Coinbase Smart Wallet, or any wallet connected through WalletConnect. Add the BNB Chain network in your wallet, then import the contract address above if your balance does not appear automatically.

The simplest way is to swap for XAUT directly on a DEX on BNB Chain. You can also buy XAUT0 tokens on other supported chains, then use the USDT0 bridge to move it to BNB Chain as XAUT. Alternatively, acquire XAUT through a centralized exchange that supports it, then withdraw and bridge it the same way.
