Polkaswap has worked to resolve some of the issues with Ethereum based DEXs. Built on Substrate, Polkaswap offers lower transaction costs and faster transactions. Polkaswap also offers swaps across Ethereum, Polkadot and Kusama networks, and more bridges are in development. In addition, with its liquidity aggregation technology, Polkaswap will allow trades against multiple liquidity sources under a custom liquidity aggregation algorithm. The liquidity aggregator algorithm can aggregate liquidity from various sources. Liquidity sources can be in the form of AMM DEXs, order books, or any other algorithm. Ultimately, this helps ensure users find the best value for their swaps.
