Pando Lake is a decentralized protocol for automated liquidity provision built with the Mixin MTG (Mixin Trusted Group) technology, an alternative to smart contracts on Mixin Network.
It uses combined algorithms - functioning on a Curve-like, bespoke low slippage, low trading fee algorithm specifically for swapping between stablecoins and on the constant product formula
x*y=k for the rest of pairs.
Each pair manages a liquidity pool made up of reserves of two tokens. The prices of the pair tokens are directly determined by the reserve balances.
Users can swap at a specific crypto assets market(pair) and/or become liquidity providers.
For the pairs
BTC-wBTC, the swapping fee is 0.04%. For the rest of pairs, the swapping fee is 0.3%.
The trading fee is paid to all liquidity providers proportional to their shares of the liquidity pool.
