Today we are excited to announce the 0x v3 bug bounty! The program pays out up to $100,000 for critical exploits and is open for participation from anyone. More details regarding areas of interest, scope of the program, and disclosure instructions can be found here.

The contracts have been audited by both Consensys Diligence and Trail of Bits (reports can be found here, here, and here). We take security very seriously at 0x and are willing to pay handsomely for any discovered vulnerabilities. In fact, the 0x bug bounty program has already paid out over $100,000 for previously discovered vulnerabilities…

We are excited to announce that 0x Protocol Version 2 has been deployed to the Ethereum mainnet! We have updated packages like contract-wrappers, order-watcher, and 0x.js with the deployed contract addresses. We also migrated our tutorials and wiki to V2, as well as the account management and order filling features of Portal. We are also pleased to open up the 0x Bug Bounty Program as of today. The program pays out up to $100,000 for critical exploits and is open to anyone — please participate if you are interested in improving the security and robustness of the 0x Protocol! Instructions…

This post outlines major development updates during the month of December 2017.

ABI to TypeScript Generator

• Release of @0xproject/abi-gen package. Our goal was to make a package that allows anyone to fully customize the templates used to generate TS code from ABI code. We use TypeScript since adding type-safety to smart contract interactions with code provides numerous benefits. You can read more about what differentiate our ABI generator from others on our recent blog post.

Changes to 0x Connect

• Websocket support. Methods for websocket subscriptions to relayers complying to the 0x standard relayer API were now added to @0xproject/connect. These allow users to easily subscribe to a relayer’s…

In November we released a blog post describing the canonical WETH token, a shared implementation of an ERC20 compatible Ether token to be used by a variety of Ethereum dApps. Since establishing the initial version of WETH, a handful of teams identified two improvements that could be made to ease dApp integration and more closely adhere to the ERC20 specification. After some discussion with other Ethereum projects and dApps, the decision to migrate to the improved version of the WETH token seemed logical. Changes included in the new WETH deployed by the Makerdao team are as follows:

• The deposit and…

In July, we published a timeline of our team’s progress that included a high level overview of our plans going forward. Since completing our token sale last month, we have made consistent progress towards our goal of fostering a diverse global ecosystem of relayers. In particular, we have been working closely with the first wave of developers that are building relayers on top of 0x protocol (Ethfinex, Radar Relay, The 0cean), hired our Developer Relations Manager Philippe Castonguay, and made numerous improvements to 0x.js. Other technical initiatives that we have been working on will be covered in the first of…

Thank you to everyone who has already registered for the ZRX token sale. At the time of this post, over 7,000 people have successfully registered and we have received overwhelmingly positive feedback from the community. You can check if your Ethereum address has been registered here.

After ongoing internal discussions, we have decided to end the registration period early in order reduce the window of opportunity for attackers to sybil attack the registration process. Registration will now close at 10pm PST on August 11th. In addition, we may add additional anti-sybil mechanisms to the process of purchasing ZRX. Please do NOT uninstall the Civic app from your device. If you have already uninstalled Civic, please reinstall the app and contact Civic support to get your account reinstated. E-mail support@civic.com, and be sure to include the phone number and e-mail you registered with.

In preparation for the upcoming ZRX token launch, we would like to provide an overview of our development roadmap for the 0x protocol and to summarize the progress our team has made to date.

Timeline

Development Roadmap

Since our work on the 0x protocol began, we have seen an explosion of interest in Ethereum and ERC20 tokens. We are thrilled because we see use cases and demand for 0x today. The first version of the protocol will be deployed on the Ethereum mainnet at the same time as our token launch, on August 15th.

What will be included in the first version of 0x?

Version 1 will be a fully functional system of…

Today we are excited to announce our project, 0x, and we are releasing our whitepaper for the community to review.

0x is an open protocol that facilitates low friction peer-to-peer exchange of ERC20 tokens on the Ethereum blockchain. The protocol is intended to serve as an open standard and common building block, driving interoperability among decentralized applications (dApps) that incorporate exchange functionality. Trades are executed by a system of Ethereum smart contracts that are publicly accessible, free to use and that any dApp can hook into. DApps built on top of the protocol can access public liquidity pools or create…
