Big upgrade just landed on SUN.io, and it directly improves how you trade on TRON, faster routing, fewer approvals, and tighter security, all under the hood.
Hereโs a clean breakdown of what changed and how you benefit ๐
๐ช๐ต๐ฎ๐โ๐ ๐ป๐ฒ๐?
SUNIo has upgraded its Smart Router and officially rolled out two powerful components:
1๏ธโฃ Universal Router
2๏ธโฃ Permit2
They work together to make swaps smoother, cheaper, and safer โ without adding complexity for users.
1๏ธโฃ Universal Router
Think of the Universal Router as a smart traffic controller for your swaps.
Instead of routing through just one pool, it can intelligently combine liquidity across multiple pools in a single transaction, including:
โซ๏ธ SunSwap V1
โซ๏ธ SunSwap V2
โซ๏ธ SunSwap V3
โซ๏ธ Curve
โซ๏ธ PSM
โซ๏ธ HTX-SUN
What this means for you:
โซ๏ธ Better pricing through aggregated liquidity
โซ๏ธ Fewer failed or partial swaps
โซ๏ธ One transaction instead of multiple steps
โซ๏ธ Cleaner execution, especially for larger trades
You just swap, the router handles the complexity behind the scenes.
2๏ธโฃ Permit2
Permit2 upgrades how token approvals work.
Instead of approving every time you interact with a new contract, you approve once and reuse that permission safely.
What changes for users:
โซ๏ธ One-time authorization instead of repeated approvals
โซ๏ธ Lower energy usage over time
โซ๏ธ Reduced friction when trading across protocols
Security is also improved through built-in controls:
โซ๏ธ Allowance limits
โซ๏ธ Signature expiration
โซ๏ธ Time-based and amount-based permissions
You stay in control, without constant approval pop-ups.
Official contract addresses (TRON)
