Liquidity providers deposit token pairs into automated market maker pools and earn a share of the trading fees paid by traders on each swap (supply-side fees).

PotatoSwap is a Uniswap V2-style constant-product automated market maker (AMM) DEX and launchpad native to X Layer, the OKX-built Ethereum Layer 2. It is the leading DEX on X Layer by TVL.

PotatoSwap is a permissionless, non-custodial protocol; liquidity providers and traders interact directly with its smart contracts. There is no registration or KYC and users retain custody of their funds.
