Polkaswap is a next-generation, cross-chain liquidity aggregator and hybrid AMM and order book DEX on the Polkadot (and Kusama) network(s), parachains, and blockchains connected via bridges. Through the development of bridge technologies, Polkaswap enables Ethereum-based tokens to be traded. This is done seamlessly, at high speed and low fees, while exchanging assets in a non-custodial manner on the SORA network. Polkaswap utilizes liquidity aggregation technology to trade against multiple sources, promising to solve critical problems AMM DEXs face, such as impermanent loss and pair fragmentation. As an open-source project, it allows the community to add more liquidity sources, enhancing its potential. Currently, Polkaswap offers cross-chain asset exchange with major Polkadot and EVM chains with TON coming soon.
