Case Studies

OpenRank

We're working with OpenRank to rank developers and GitHub repos on recursive trust for the entire GitHub activity graph. We also have a public version of their trust scores for Farcaster users.

Passport

We work with Passport on trusted user labeling and identity management. We maintain a public dataset of their address scores, which gets leveraged for onchain impact measurement.
