Sun Swap - Trade Tokens on TRON

SunSwap

Trade TRC-20 tokens

A sun swap is a trade on SunSwap, the DEX inside SUN.io. You choose a token you hold and a token you want. The liquidity pool sets the price from its balances. There is no order book. Sunswap and tron swap are the same search: a TRC-20 exchange on TRON, signed from a wallet you control. The app people open is sun io, at sun.io.

The quote you see is for the size you typed. A larger trade moves the pool price more. That movement is slippage, not a hidden fee. The pool fee depends on the route. The V2 example in the SUN white paper deducts 0.3%. A V3 pool uses one of four tiers: 0.01%, 0.05%, 0.3%, or 1%. TRON also charges energy and bandwidth. SunSwap V4, live since 2 March 2026, can pair native TRX and announced energy subsidies of up to 99% on V4 swaps.

You do not hand the tokens to a custodian. An approval, when the wallet asks for one, lets the router spend a TRC-20. The swap is a second signature. The output token returns to the same address. If the names on the screen are not the tokens you meant, do not sign.

How to swap

1. Connect TronLink or another supported wallet and keep TRX for energy.
2. Pick the pay token and the receive token. Read the pool, not just the ticker.
3. Check the output, the fee, and the price impact.
4. Approve if asked, then sign the swap. Confirm the result in your wallet.

Frequently asked questions

How do I do a sun swap?

Open the swap on sun.io, connect a TRON wallet, choose the two tokens, read the quote, and sign. The pool sets the price. You keep the keys.

Is a tron swap on SunSwap the same as a centralized exchange trade?

No. A centralized trade matches an order book and the exchange holds the balance. A SunSwap trade moves tokens through a pool contract in your own wallet.

Why did my quote change?

Pool balances move as other people trade. The output also falls as your size consumes liquidity. That is price impact, on top of the pool fee and TRON energy.
