Polygon Integrates USDT0 and XAUt0 for Cross-Chain Liquidity
Polygon has announced the on-chain launch of Tether’s cross-chain stablecoins USDT0 and XAUt0, leveraging LayerZero’s OFT technology. With this integration, Polygon becomes the 11th network supporting USDT0 and the third for XAUt0 after TON and HyperEVM. Existing PoS USDT will upgrade in place to USDT0 under the same contract address, tapping into over $1 billion in Polygon USDT liquidity and more than 6 million wallets. XAUt0 introduces native, gold-backed liquidity to Polygon, aligning with DeFi, payments and real-world asset adoption. Polygon’s AggLayer upgrade and Bhilai hard fork further bolster its cross-chain capabilities. The integration pushes USDT0 supply past $1 billion on Polygon, while Tether’s USDT market cap exceeds $167 billion and XAUt0 overall supply tops $1 billion.
Bullish
The integration of USDT0 and XAUt0 on Polygon enhances cross-chain liquidity and on-chain gold exposure, driving stablecoin adoption and DeFi activity. Polygon’s upgrade path and high USDT liquidity have historically attracted trading volumes and decentralized finance growth. By upgrading existing PoS USDT contracts and introducing XAUt0, Polygon solidifies its role as a leading stablecoin hub, which is expected to boost both short-term transaction volume and long-term ecosystem expansion.
