SUN.io Launches SunSwap V4

According to the official announcement, the SUN.io platform will officially launch SunSwap V4 on March 2, 2026. This is a comprehensive upgrade to the AMM architecture.

SunSwap V4 significantly reduces energy consumption for multi-hop transactions and complex strategies by introducing a singleton pattern and flash accounting mechanism, and restores direct support for native TRX, enabling seamless transactions without wrapping. The new version also provides developers with powerful 'hooks' customization capabilities, allowing support for dynamic rates and on-chain oracles without modifying the core protocol; at the same time, V4's custom accounting allows hook developers to flexibly adjust user operations through differentials, enabling custom fees, strategies, and curves. Additionally, a brand new notification mechanism has been introduced, allowing real-time notifications via subscriber contracts. At the same time, users exchanging through SunSwap V4 will enjoy up to 99% energy subsidies, inviting users to experience more efficient and lower-cost decentralized trading.
