# Stable Swap

Algorithm for stable asset swap is similar to [Curve.finance](https://onchaintrade.gitbook.io/ot/spot-and-borrow/swap/www.curve.fi) with low slippage and low [fee rate](/ot/fee-policy.md)

x + y = k when the stable coin de-peg percentage is smaller than 5%

When a stable coin de-peg equal or more than 5%, swap applies x \* y = k algorithm.
