Dear users,
The SUN platform officially launched SunSwap V4 on March 2, 2026 (Singapore Time). SunSwap V4 is a comprehensive upgrade to previous AMM designs. Its core objective is to retain the AMM foundations of V1/V2 and the concentrated liquidity model of V3, while providing developers with additional customization capabilities and significantly reducing energy consumption during transactions through fundamental architectural innovations.
Key Features of SunSwap V4
- Native TRX Support:
Restores support for native TRX, allowing TRX to be paired directly with TRC-20 tokens. Users no longer need to wrap TRX into WTRX, making operations simpler and further reducing transaction energy costs. - Singleton Architecture:
Replaces the traditional factory model with a single contract that manages all liquidity pools. This design greatly reduces pool creation costs and significantly lowers energy consumption for multi-hop swaps. - Flash Accounting:
A new accounting mechanism enabled by the singleton architecture. The system records only net balance changes (deltas) internally and settles them at the end of the operation—drastically reducing energy overhead for complex trading strategies. - Hooks:
Enables custom logic execution at key points such as swaps and liquidity additions. Developers can implement advanced features like dynamic fees, custom curves, on-chain oracles, etc., without modifying core protocol code. - Custom Accounting:
Allows hook developers to flexibly adjust user actions via deltas, enabling custom fees, strategies, and curves. - Subscribers:
Introduces a new notification mechanism. Liquidity providers (LPs) may opt into subscriber contracts to receive real-time position change notifications, enabling seamless, non-custodial liquidity management.
Meanwhile, users who perform swaps through SunSwap V4 will also enjoy energy subsidies of up to 99%.
The launch of SunSwap V4 marks a new stage in the platform’s system capabilities. We will continue to provide the community with a safer, more efficient, and scalable DeFi trading experience. You are welcome to try it out!
Thank you for your continued understanding and support!
