Gold has endured for thousands of years because it represents something fundamental: lasting value. Entire civilizations and currencies have risen and fallen over the ages while gold remains trusted and coveted. And with the price of gold reaching all-time highs recently, it’s time for the world’s most enduring store of value to become as composable and accessible as the networks that increasingly define global capital flows.
That’s why we’re proud to introduce XAUt0: the omnichain evolution of Tether Gold (XAUt). The first deployment of XAUt0 will take place on The Open Network (TON), in collaboration with the TON Foundation. With this, we're freeing the most trusted gold-backed onchain asset across the world’s leading networks via a unified, frictionless liquidity layer. This unlocks new economic potential for everyone from institutional investors to developing nations in need of a battle-tested, borderless store of value.
What is Tether Gold (XAUt)?
Launched in 2020, Tether Gold (XAUt) was one of the earliest and most successful projects to bring real-world assets onchain at scale. By combining the reliability of physical gold bullion with the transparency and accessibility of blockchain technology, XAUt offers the best of both worlds: a timeless hedge against inflation, delivered with the flexibility and freedom that modern finance demands.
According to Tether’s Q1 2025 attestation, there are currently over 7.7 tons of physical gold backing all XAUt in circulation, with a market capitalization of $770 million. Each XAUt token represents ownership of one troy ounce of London Bullion Market Association-certified gold, securely stored in a dedicated Swiss vault. All physical reserves are independently verified following ISAE 3000 (Revised) standards, including inventory checks and sample testing.
There are many benefits to owning XAUt instead of directly holding physical gold, including:
-
24/7 Access: While traditional gold markets close for weekends and holidays, XAUt0 holders can buy, sell, lend, or use their digital gold at any time, from anywhere.
-
Secure Digital Storage: XAUt holders enjoy the economic security of gold with the self-custody of digital wallets, without the costs and hassle of physical custody.
-
Infinite Divisibility: XAUt can be bought and sold in fractional increments, opening up new possibilities for everything from collateral provision to portfolio diversification.
-
Physical Redemption Options: Unlike most other “gold investment” options, XAUt holders can redeem their tokens for physical gold, delivered to a Swiss address.
This represents a seismic shift in how gold is owned and used by institutional investors, sovereign web3 citizens, and everyone in between. But until now, XAUt’s deployments have been limited to a handful of chains, limiting its reach and potential.
XAUt0 Takes XAUt Anywhere Onchain
As the omnichain deployment of Tether Gold, XAUt0 frees the world's largest gold-backed digital token across the world's leading blockchains via a frictionless, omnichain liquidity layer. Built on LayerZero’s Omnichain Fungible Token (OFT) standard, XAUt0 allows users to seamlessly and securely move their gold between chains while ensuring full 1:1 backing via XAUt’s physical holdings.
In addition to all the benefits of native XAUt, XAUt0 unlocks:
-
Omnichain Access: Move XAUt0 natively anywhere onchain without wrapping or redeploying new tokens on each chain.
-
Enhanced Capital Efficiency: Leverage deep gold-backed liquidity pools that facilitate healthier, cost-effective market activity.
-
Atomic Mint-and-Burn: Move your gold confidently across chains, with all cross-chain minting and burning occurring simultaneously once fully validated.
-
Limitless Composability: Power new use cases that integrate gold as an DeFi asset rather than just passive storage, from multichain lending to gold-FX arbitrage strategies.
As a result, XAUt0 allows users to own a physically backed, inflation-resistant asset while tapping into the full composability and financial innovation that web3 offers.
XAUt0: The Most “Liquid” Form of Gold
Today’s financial landscape already offers multiple ways to “invest” in gold, from rare metal ETFs to tokenized price trackers. But most of these options offer little more than indirect price exposure, without true ownership rights and the ability to freely use or move holdings.
XAUt0 changes that. By combining the direct, physical gold ownership of Tether Gold with the frictionless, omnichain liquidity layer pioneered by USDT0, XAUt0 modernizes gold for the decentralized era. The end result is a globally accessible, infinitely programmable form of gold that retains the reliability and timelessness of the original asset.
So while Bitcoin is often considered “digital gold” due to its trustless scarcity model, XAUt0 introduces “digital gold” that is both physically backed and built for the omnichain future. This is liquid gold, redefined.
