SunSwap Stablecoin Pool

StableSwap on SUN.io

A stablecoin sun swap should not use the same curve as a volatile pair. SUN.io runs a separate stablecoin pool on the StableSwap model. Near a one-to-one peg, the price barely moves, so slippage stays low. Far from the peg, slippage rises and arbitrage pulls the pool back. The curve never runs a balance to zero, which is why liquidity does not disappear at an extreme price. The SUN white paper describes this as the right tool for USDT and the other stablecoins on TRON, and the wrong tool for assets whose prices diverge.

The white paper names a 3pool of USDT, USDJ, and TUSD, and a later USDC pool. Treat that as the design SUN.io published. The pairs you can actually trade are the ones listed on sun.io now. Impermanent loss in this pool stays smaller than in a constant-product sunswap pool while the coins hold their pegs. If a coin breaks its peg, the pool will hold more of the weaker asset, the same way any pool does.

Fees are split differently here. SUN.io grants 50% of stablecoin-pool trading fees to veSUN holders. veSUN is locked SUN, not the LP token. Liquidity providers still supply the depth. The other half of the fee design is the reason people lock SUN. A normal V2 pool's fee goes to LP tokens, with 0.05% of V2 volume used to buy back and burn SUN. Do not mix those two fee paths.

When to use the stable pool

  1. Use it to move between pegged TRON stablecoins when you want low slippage.
  2. Do not use it for a volatile pair. The curve assumes prices stay near each other.
  3. Providing liquidity means holding the stablecoins in the pool, not locking SUN.
  4. veSUN is what receives 50% of the stablecoin-pool trading fees.

Frequently asked questions

What is the SUN.io stablecoin pool?

It is a StableSwap pool for pegged assets on TRON, separate from constant-product SunSwap pools. Swaps near the peg have low slippage. The white paper describes pools such as USDT, USDJ, and TUSD.

Who receives stablecoin-pool fees?

Liquidity providers supply the pool. SUN.io grants 50% of the trading fees in the stablecoin pools to veSUN holders, which means people who have locked SUN.

Is this the same as a SunSwap V3 0.01% pool?

No. V3 0.01% is a concentrated-liquidity tier aimed at large stablecoin flow. The stablecoin pool is a different curve, StableSwap, with its own fee share to veSUN.
