AB Chain's high-performance network brings zero-fee transfers and instant settlement experiences to USD1. At the same time, AB Wallet, as the native wallet, achieves full compatibility with all chains where USD1 is deployed. USD1 is currently deployed on Ethereum, BNB Chain, and Tron, and now joins AB Chain. The multi-chain strategy makes USD1 the foundational liquidity infrastructure across ecosystems. DeFi protocols can integrate USD1 on any supported chain, giving developers greater design flexibility. AB Chain's DeFi and payment ecosystem will gain stronger stablecoin support with the addition of USD1, benefiting scenarios like trading, lending, and liquidity. From single-chain deployment to multi-chain expansion, USD1 is building a truly global stablecoin infrastructure. The partnership with @ABDAO_Global is just the beginning, with more practical use cases coming soon
