Projects

Tidbit

Tidbit is a modular oracle library that enables developers to compose decentralized oracles. We believe oracles are one of the largest under-addressed needs for decentralized applications. Our hope is that Tidbit will encourage collaboration and experimentation around building oracles, bringing a broad range of blockchain applications closer to reality.

Registry Library

A library with modular contracts for Token Curated Registries. Allows developers to more easily mix and match features and challenge mechanisms.

Futarchy

Token Curated Registry implementation that utilizes futarchy prediction markets to determine the outcome of listing challenges.

OpenZeppelin Audit

OpenZeppelin is the most widely used smart contract framework boasting over 10,000 weekly downloads. We integrated with the OpenZeppelin team to turn around a comprehensive audit report on a very tight deadline.
