StableSwap

Macaron supports StableSwap of various trading pairs such as stBTC/BTC.

• stBTC is the official Liquid Principal Token (LPT) issued by staking BTC in Lorenzo Protocol, pegged to the value of BTC. It represents the right to claim staked BTC when staking is over. It allows Bitcoin stakers to maintain liquidity while staking, avoiding fragmentation by standardizing stBTC for all low-risk staking plans.

The StableSwap is an implementation of Curve Finance’s AMM on Macaron. It adds 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, 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.

How to trade StableSwap?

Trading on the StableSwap is very similar to using the existing MacaronDEX AMM. Before we start, it also requires a Bitlayer mainnet wallet and BNB for gas fees. Please check our wallet guide for more details.
