Application-specific blockchain for decentralized exchange, a parachain in Polkadot ecosystem. Implementation includes MEV solution, Proof of Liquidity and no gas economy.

Reliable decentralized exchange (DEX) blockchain - interoperable with other blockchains using Polkadot. The exchange is using a consensus algorithm that solves MEV/frontrunning problems and makes all participants' access to trading opportunities equal.

The design of the blockchain guarantees fixed-fees that provides greater control of trading costs and higher arbitrage opportunity. Assets on the exchange will serve multiple purposes- at the first iteration, they are the block producer’s stake and exchange liquidity at the same time, and more comes later.
