Polkastarter is a DEX built for cross-chain token pools and auctions, enabling projects to raise capital on a decentralized, permissionless and interoperable environment based on Polkadot. In order to leverage advantages, smooth interoperability between various networks is a key to success. The key feature of Polkastarter is the possibility of making cross-chain swaps, powered by the Polkadot ecosystem, which can provide higher throughput for faster and cheaper transactions while staying connected to the Ethereum Network and other blockchains for liquidity.
