TechFlow News: On February 5, SUN.io announced the completion of a major upgrade to its smart routing system, officially integrating the Universal Router and Permit2 protocols. Following 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. Additionally, Permit2’s one-time high-amount approval, configurable signature expiration, and quota mechanisms significantly reduce the energy cost associated with repeated approvals while enhancing security.
The official team has published the TRON Mainnet contract addresses for Permit2 and the Universal Router, urging users to interact exclusively with these officially disclosed contract addresses to safely access a more efficient trading experience.
