Dear users,
To further optimize the trading experience and improve system performance, SUN.io has completed the upgrade of its Smart Router contract and V2 Router contract. This upgrade keeps the contract interface invocation unchanged and aims to allocate valuable energy subsidy resources more centrally to the latest contracts of core business operations, thereby maximizing resource utilization.
Details of the contract upgrade comparison are provided below:
| Contract Type | New Contract Address | Old Contract Address |
| smartrouter | TGnC7LMji8hBpyvZt1TTEJhVpAZ5HFyJ3r | TCFNp179Lg46D16zKoumd4Poa2WFFdtqYj |
| pumpSmartRouter | TGnC7LMji8hBpyvZt1TTEJhVpAZ5HFyJ3r | TSiiYf1b1PV1fpT9T7V4wy11btsNVajw1g |
| V2Router | TMmRKgwC1hx4azzkXoPzujgQThzF48Actq | TXF1xDbVGdxFGbovmmmXvBGu8ZiE3Lq4mR |
| pumpV2Router | TMmRKgwC1hx4azzkXoPzujgQThzF48Actq | TZFs5ch1R1C4mmjwrrmZqeqbUgGpxY1yWB |
Along with the contract upgrade, starting from December 30, 2025 (Singapore Time), the energy subsidy policy will be adjusted as follows:
- Upgraded new contracts: Will continue to enjoy energy subsidies of up to 99%;
- Replaced old contracts: Energy subsidies will be discontinued as of January 14, 2026 at 23:59:59 (Singapore Time);
- Other business-related contracts: Subsidy policies remain unchanged.
This upgrade will not affect normal usage. Through more efficient resource allocation, we will continue to provide a more stable, secure, and seamless on-chain trading experience.
Thank you for your continued understanding and support!
