class=”ql-align-center”>Unlocking Unified Liquidity for the Next Generation of Onchain Finance

Today, one of the fastest-growing ecosystems in modern finance, Polygon , officially upgrades to the USDT0 standard, the unified liquidity network for the world’s most widely used stablecoin Tether (USDT), and XAUt0, the omnichain evolution of Tether Gold , the the digital representation of gold, one of history’s most trusted stores of value. 

By integrating USDT0 and XAUt0, Polygon is unlocking fast, frictionless liquidity for DeFi, payments, and real-world asset (RWA) applications across the Polygon stack. 

USDT0 is already one of the fastest-growing stablecoin networks in crypto. In less than a year, it has surpassed $10.5 billion in bridge volume across 210,000+ cross-chain transfers and supports over 100 chain pathways, making it the most active OFT in the LayerZero ecosystem.

Whether users are borrowing in DeFi apps or moving capital between rollups, they can now use USDT0 and XAUt0 without relying on bridges or wrapped tokens. XAUt0, the omnichain version of Tether Gold, adds a second pillar of composable value to the ecosystem. 

For the first time, developers on Polygon can natively integrate gold-backed collateral into borrowing, hedging, and asset management strategies. As demand for real-world asset integrations accelerates, native gold liquidity strengthens Polygon’s position as a hub for institutional-grade, asset-backed innovation.

“Unified liquidity is what makes the multichain future actually work,” said Lorenzo R., Co-Founder of USDT0. “Now that USDT0 and XAUt0 are live on Polygon, it’s a lot easier for builders to plug into the assets that matter most, on a chain that’s built for serious scale. Whether you’re moving funds between rollups or building a new DeFi or RWA platform, this makes everything faster, simpler, and more connected.”“Polygon’s integration of USDT0 and XAUt0 marks a major step in making asset-backed liquidity seamless across the multichain ecosystem,” Aishwary Gupta, Head of Enterprise at Polygon Labs, said. “For our builders, it means direct access to two of the most trusted digital assets, the world’s leading stablecoin and gold, without the friction of bridges or wrapped tokens. For enterprises and institutions, it’s another example of how Polygon is delivering the scale, security, and asset diversity needed for real-world finance to thrive onchain.”

The addition of USDT0 and XAUt0 brings stable and asset-backed liquidity natively to anyone building in the ecosystem. Polygon has emerged as one of the most important platforms in modern onchain finance, not just as a high-performance Layer 2, but as a full-stack, multichain coordination layer. Beyond infrastructure, Polygon is rapidly becoming the go-to destination for enterprise and institutional adoption, with Fox Corporation’s Verify protocol for content authentication, financial institutions like Libre launching institutional Web3 infrastructure for alternative assets, and major brands including Warner Music Group, Nike, Reddit, Starbucks, and Disney building on the platform..

USDT0 is now available on 12 leading protocols and chains, including Arbitrum, Berachain, Ethereum, Ink, Flare, Optimism, Plasma, HyperEVM, SEI, and Rootstock, a 100% increase in interoperable accessibility. Thanks to a concerted effort between USDT0 and the Polygon Foundation, the upgrade to USDT0 retains the same contract address as the previously bridged version of USDT on Polygon. This ensures a seamless transition, users, centralized exchanges, and protocols are not required to take any action during the upgrade.
