According to official Odaily, SUN.io has announced a major upgrade to its smart routing system, officially introducing the Universal Router and Permit2 protocols. After the upgrade, users can complete optimal path exchanges across multiple liquidity pools, including SunSwap V1/V2/V3, Curve, PSM, and HTX-SUN, in a single transaction. Simultaneously, the Permit2 protocol's one-time high-limit authorization and signature validity and limit mechanisms significantly reduce the energy costs of repeated authorizations and improve security.
The official Tron mainnet Permit2 and Universal Router contract addresses have been released. Users are reminded to interact with the officially disclosed contract addresses to securely enable a more efficient trading experience.
