Start developing on 0x v2.0 + trade through 0x relayers at 0x.org/portal.



We are incredibly excited to announce that we have completed mainnet testing for 0x protocol v2.0! After over a year of development, and numerous rounds of internal and external security audits, we are confident that this new system of Ethereum smart contracts is one of the most highly vetted systems on the Ethereum blockchain.



The launch of v2.0 is an important milestone in 0x’s long-term mission of creating a tokenized world where value can flow freely. Version 1 enabled developers to create beautiful user experiences, tap into public pools of liquidity, reduce development time, and lower costs associated with trading. Version 2.0 brings further modularity and extensibility, allowing developers to address many new use cases. Over the past year, we have not only seen an explosion in the number of ERC20 tokens, we have also seen a growing set of new token standards such as ERC721 for non-fungible tokens (NFTs). 0x Protocol v2.0 addresses the needs of both developers and end users to access and exchange all types of new digital assets as they emerge.



Over the past year the 0x core team has not only been building, we have also been listening. To relayers, Solidity devs, UX designers, market makers, community members, dApp devs, and others. By gathering all of this feedback, we have been able to include features in 0x protocol v2.0 that will pleasantly surprise developers, bring a new wave of high-quality projects onto 0x, and set up the system for future upgrades and improvements through governance.



The 0x core team is grateful for all of our passionate supporters in the community and we look forward to supporting you as you find new ways to utilize v2.0!
