PolkaEX is a cross-chain trade platform based on Polkadot, using Plasm Network to provide higher TPS, lower transaction cost, smooth trade protocol. PolkaEX not only a decentralized exchange, but also an integrated trading platform with many functions, such as Polkaex Launchpad, and more in the future. Providing a one-stop asset trading platform. With the rapid development of Polkadot’s ecosystem, more and more projects on Ethereum begin to move to Polkadot, such as ChainLink, 1Inch, Ocean Protocol, etc. The parachain slots auction has not yet started, and there are 388 projects ready to build para chains on Polkadot. So for the foreseeable future, the Polkadot ecosystem will get bigger and bigger. The blockchain future will be a multi-chain world, where tokens on multi-chains will need to interact on different chains, which requires interoperability. Decentralized exchanges need to solve the problem of fast confirmation and low fees if they are to become widespread. Therefore, there is a need for Layer 2 solution.
