USDT0 is the unified liquidity network for Tether’s US dollar–pegged stablecoin USDT. It also has the Tether’s gold stablecoin XAUT. USDT0 officially announced the launch of XAUT0, a new stablecoin built on LayerZero’s Omnichain Fungible Token standard, enabling crosschain transactions without wrapping or middle chains. The XAUT0 token will compete with other gold-backed stablecoins and traditional gold investment instruments. The most trusted gold-backed asset will be available on the world’s leading blockchains starting now with the TON blockchain.

XAUT is the largest gold stablecoin with over $832 million market capitalization. It is available only on the Ethereum blockchain. Tether has more than 7.7 tons of physical gold backing the XAUT stablecoin. Each XAUT token represents one troy ounce of the global asset, which is reportedly being stored in a Swiss vault. The XAUT0 launch comes months after the network introduced the USDT0 stablecoin, a crosschain dollar-backed stablecoin deployed across Optimism’s Superchain, an ecosystem that has at least eight blockchains.

Gold is considered a safe-haven asset and in 2025 has experienced a big appreciation in price due to economic uncertainty, particularly due to ongoing global trade wars. The gold’s price was $3,304 per ounce on May 30, up $2,327 from a year ago — a 29.5% jump in 12 months. Also the gold exchange-traded funds (ETFs) have experienced significant grow this year with the eight top funds experiencing increases of more than 25%. The Gold ETFs are a popular way to trade the asset. Tether’s omnichain gold token will compete with similar ETFs and other traditional gold investment instruments.
