Tether Launches Cross-Chain Version of Tether Gold Stablecoin

Tether has unveiled a new project, XAUt0, created on the basis of its “golden” stablecoin Tether Gold with the participation of developers from LayerZero. This token will become part of the cross-network ecosystem and will be integrated primarily into the TON blockchain with the support of the TON Foundation.

Earlier, in January 2025, a similar initiative was launched — USDT0, which is a version of the USDT spot token compatible with several networks. This asset currently functions on the Arbitrum, Berachain, Hyperliquid, Flare, and Ink blockchains, which belongs to the Kraken crypto exchange. Although both projects — XAUt0 and USDT0 — are positioned as elements of a single ecosystem, Tether itself emphasizes that they are not considered direct products of the corporation. Each XAUt0 token is a digital copy of the original XAUt asset, which is backed by one troy ounce of physical gold stored in Switzerland.

Thus, the new version retains full redundancy and uses the same gold reserves as the standard XAUt. The technical basis for XAUt0 was the OFT (Omnichain Fungible Token) protocol from LayerZero, which allows tokens to be moved between different blockchains without the need to convert them. This makes the asset highly liquid and convenient for use across different chains.

The new token is designed as a universal tool for the Web3 economy: it can be used for both simple P2P transfers and complex DeFi products. In the announcement of the launch of XAUt0, it was called “the most liquid form of gold”, emphasizing its potential for use in the decentralized financial system of the future.
