Announcing 0x OTC

We are excited to announce the alpha release of our first user facing product, 0x OTC, a decentralized application that facilitates trustless over-the-counter trading of Ethereum-based tokens using 0x protocol. In this initial release, our open source smart contracts have been deployed to the Kovan test network where users are able to acquire test tokens and trade within their social network. We will continue to support and improve 0x OTC over time as we transition our smart contracts to the main Ethereum network in coming months.

Over-the-counter trades take place directly between counterparties without the assistance of an exchange. In the context of 0x protocol, users can generate and cryptographically sign orders that adhere to 0x message format, share these orders using a variety of off-chain communication channels and execute trades directly on the blockchain. Users may inspect their trades both within 0x OTC as well as on Etherscan’s block explorer for the Kovan network.

Inspect your trades on the Etherscan block explorer.

How does 0x OTC fit within the scope of our development roadmap?

We envision 0x protocol serving as a critical piece of infrastructure within the emerging token economy, giving way to an ecosystem of highly liquid markets representing a variety of assets on the Ethereum blockchain. 0x OTC provides a small glimpse of what this foundational technology is capable of and represents the first of many steps we will take towards realizing our vision.

It is important to point out that 0x OTC does not provide a real-time public order book. This decision was intentional: we believe the shortest path towards realizing our vision is to massively lower the barrier to entry for independent for-profit exchanges to build on top of 0x. In turn, these exchanges will compete for transaction fees by creating increasingly user friendly and performant web applications targeting a variety of markets and demographics.
