0x v2.0 Launches On Ethereum Mainnet


September 25, 2018 7:01 PM

The newest version of the protocol is now live.

On Monday, September 24, Will Warren of 0x announced the launch of v2.0 of the exchange protocol. This release comes from more than a year of development and various rounds of security audits, both internal and external. He indicated "that this new system of Ethereum smart contracts is one of the most widely used systems on the Ethereum blockchain."

Warren went on to note that v2.0 marks "an important milestone in the 0x's long-term mission of creating a tokenized world where value can flow freely." While the protocol is the initial version accomplished a few feats, such as "creat[ing] beautiful user experiences "and" lower[ing] costs associated with trading, "the newest iteration" brings further modularity and extensibility "to the protocol that allows developers" to address many new use cases. "

This focus on modularity and extensibility is partly informed by the proliferation of ERC20 tokens, as well as by the emergence of different token standards, such as ERC721 for non-fungible tokens. According to Warren, this is a case in which we arise.

The new contract architecture of v2.0, for instance, directly includes support for ERC721, ERC20, and other token standards. "Look forward to trading" [their] ENS names, ERC-777 tokens, and R-Tokens using 0x in the future! "

Some other key features of the recent release EIP 712 and Trezor, as well as atomic order matching, which allows orders to be "matched and filled together without requiring capital other than ETH to cover gas costs."

Warren has been listening to its followers – including relayers, Solidity developers, and others in the community – and using their feedback to ultimately.

A little bit prior to the mainnet launch, ConsenSys Diligence, an EDCC auditing service, published results for its comprehensive audit of 0x v2.0. The auditors observe that the protocol includes well-written specification documents, as well as a thoughtfully consistent and organized contract repository. The audit team identified 25 issues of varying severity, 13 of which were addressed by the time ConsenSys Diligence released its report.
