SeaLightSwap is a Polygon infrastructure project that builds liquidity for AMMs and partnering projects. Liquidity Providers ("LPs") stake their token pairs in "Pools" on the DEX. In exchange, they receive LP (Liquidity Provider) tokens. Fees Are 0.3% For Liquidity Providers. You can trade coins using only smart contracts and liquidity pools. Since wallets only interact with smart contracts there is not any central entity ensuring self custody of tokens
