# Smoothy

Smoothy is a novel solution for swapping assets that are effectiverly backed by the same underlying assets (e.g., stablecoins) with a single pool, comprising a set of interoperable protocol smart contracts deployed on the Ethereum-compatible blockchains, and offers:

* Simple and smooth swap
* Extremely low gas fee
* Flexibility to add/remove any tokens that backed by the same asset into the pool
* Better liquidity/lower slippage
* Better LP token incentives

## Comparison
