Polygon has officially integrated USDT0 and XAUt0, expanding its ecosystem with a unified liquidity network for stablecoins and Tether Gold, enabling seamless onchain finance applications.

This integration is supported by infrastructure upgrades like AggLayer and Bhilai Hardfork, which improve scalability and cross-chain compatibility, making Polygon an ideal platform for omnichain stablecoins and DeFi expansion.

Launched in January 2025, USDT0, the omnichain version of USDT, has quickly grown to nearly $1.6 billion in market cap and is now the most supported stablecoin on Polygon, which is its 12th supported blockchain.

USDT0 has supported over $10.5 billion in bridge volume across more than 210,000 cross-chain transfers, and is supported on over 100 chains, making it one of the most active OFT networks within the LayerZero ecosystem.

USDT0 is accessible on 12 protocols and chains, including Ethereum, Arbitrum, and Optimism, with a seamless upgrade process that preserves the same contract address for user convenience.

The integration allows users and developers to transfer funds between different chains and rollups without relying on bridges or wrapped tokens, boosting liquidity and usability for DeFi, payments, and real-world assets.

Everdawn Labs manages USDT0 and XAUt0, focusing on scalable cross-chain liquidity solutions, with Polygon Labs leading the development of Polygon’s Web3 infrastructure.

USDT0 and XAUt0 are not directly backed by assets but are minted on Ethereum by depositing USDT or XAUT into specific contracts, representing an interoperability layer for these stablecoins.

All tokens minted across networks are backed by reserves locked on Ethereum, ensuring supply consistency and seamless transfers across multiple blockchains.

The adoption of omnichain stablecoins like USDT and XAUT highlights growing demand for interoperability, with USDT surpassing $167 billion in market cap and XAUT exceeding $1 billion, emphasizing their role in digital payments and tokenized assets.

Polygon has become the eleventh blockchain supporting USDT0 and the third for XAUt0, following deployments on TON and Hyperliquid’s HyperEVM, marking significant milestones in adoption.

Polygon aims to position itself as a full-stack, multichain platform for modern onchain finance, backed by partnerships with major brands such as Warner Music Group, Nike, Reddit, Starbucks, and Disney, supporting various enterprise initiatives.
