The interface is straightforward-select tokens, enter amount, and approve the transaction. Users report completing swaps in under a minute.

What tokens can I trade?

Recent data shows WTRX and USDT dominate activity, but newer tokens like LMTV are gaining traction. Check the platform’s token list for the latest additions. In 2025 alone, over 6 million transactions involved top tokens like WTRX and USDT.
Are there fees?
Yes, a fixed 0.3% fee per trade. This fee goes directly to liquidity providers, not SunSwap. It’s consistent across all swaps, making it easy to calculate costs. For comparison, some centralized exchanges charge higher fees for similar trades. Liquidity providers earn these fees as passive income, which is why many users contribute to pools.
Why are there two web addresses?
SunSwap V2 uses sunswap.io and sunswap.exchange to improve accessibility. However, this can confuse new users. Always verify the official site to avoid phishing scams. The developers recommend sunswap.io as the primary address. Some users report issues with the second domain, so sticking to one is safer. In 2025, 99% of traffic came from organic searches on sunswap.io, showing it’s the preferred choice.
