SUN.io Smart Routing System Completes Upgrade, Introduces Universal Router and Permit2 Protocol

According to official updates, SUN.io announced the completion of a comprehensive upgrade to its smart routing system, formally introducing the Universal Router and Permit2 protocol. After the upgrade, users can execute optimal path swaps across multiple liquidity pools including SunSwap V1/V2/V3, Curve, PSM, and HTX-SUN in a single transaction. Simultaneously, by leveraging Permit2's one-time high-limit authorization, signature validity period, and quota mechanism, the upgrade significantly reduces the energy consumption costs associated with repeated authorizations and enhances security.

The official team has published the Tron mainnet contract addresses for Permit2 and Universal Router, reminding users to interact only with the officially disclosed contract addresses to safely enable a more efficient trading experience.
