StableSwap

StableSwap on Trading Post is a feature to trade stable pairs with a lower slippage based on an invariant curve slippage function. It is designed to swap specific assets that are usually priced closely - such as stablecoins or liquidity-staking tokens.

The StableSwap is an implementation of Curve Finance's AMM on Trading Post. It adds a linear invariant constant sum curve (x+y=K) on top of the constant product formula (x*y=k) to keep prices more equal as long as the liquidity pool is not extremely unbalanced. As a result, since StableSwaps are restricted to similarly priced assets, the impermanent loss is not as much of a concern (except in extreme depeg cases) and the slippage is lower than normal AMM which just uses the constant product formula.

When you conduct a Swap (trade) on the StableSwap you will pay lower trading fees, than the usual 0.25% on Exchange V2 AMM.

StableSwap Fees

Fees for each pair are broken down per trading pair.

The team will gradually roll out StableSwap pairs and revise the fees to test and improve the experience further.

Why should I use the StableSwap instead of the normal AMM?

• Swap your stablecoins or other pairs with similar asset prices more efficiently with the same trade steps

• With the StableSwap function, the trading pair slippage is lower than normal AMM

• The StableSwap trading fees are lower compared to the normal AMM
