TechFlow News: On March 2, according to the official announcement, the SUN.io platform officially launched SunSwap V4 on March 2, 2026—a comprehensive upgrade to its AMM architecture.
SunSwap V4 significantly reduces energy consumption for multi-hop trades and complex strategies by introducing a singleton pattern and lightning accounting mechanism. It also restores native TRX support, enabling seamless, wrapperless trading. The new version provides developers with powerful customizable “hooks,” allowing dynamic fee structures and on-chain oracles without modifying the core protocol. Additionally, V4’s customizable accounting enables hook developers to flexibly adjust user operations via delta-based logic—supporting custom fees, strategies, and curve configurations. Furthermore, a brand-new notification mechanism has been introduced, enabling real-time notifications through subscriber contracts. Users swapping tokens via SunSwap V4 will also enjoy up to 99% energy subsidies. We invite you to experience decentralized trading with higher efficiency and lower costs.
