Evodex is a joint contribution to the EOS DE-FI ecosystem by two Block Producers.
The smart contract was created by EOS Argentina and it allows anyone to launch and interact with continuous liquidity pools in a decentralized exchange. The front-end and web interface was provided by EOS Costa Rica as a bridge to access the Evolution Dex Protocol. With this contribution both teams wish to help foster the growth of Decentralized Finance on EOS, a blockchain that has the best capabilities to run complex systems due to its transaction capacity and fee-less model.
Evodex facilitates the decentralization of exchanges and promotes the use of EOS for financial instruments. The project is completely open source and free for any developers who wish to integrate it to their front end. In this way different exchanges can share the same liquidity and contribute to the growth of the protocol.
The main difference from say Uniswap on Ethereum, is that liquidity providers can vote for the fees they want to charge using a smart contract that calculates the fees proportional to the stake of every participant of the pool.
Another difference between EVODEX and UNISWAP comes from the different blockchains where they both operate, traders only pay fees to liquidity providers, but they don't have to pay transfer fees like in Ethereum and other networks.
