We know it has an open protocol for the Ethereum blockchain and decentralized exchanges. The developers of 0x think that in the future all assets will be equal to coins, they aimed to create a reliable platform that would allow all these tokens to be exchanged for each other. With this system, users will be able to create their contracts through exchanges. The 0x (ZRX) system aims to fairly correct the drawbacks of swaps at this point. In exchanges based on the 0x system, transactions are first processed outside the chain, after the contracts are made intelligently, if they are approved, then these contracts are transferred into the chain.
