About
Self Protocol is a privacy-first, open-source identity protocol powered by zero-knowledge proofs. It allows developers to verify users’ identity and humanity (including sybil resistance, age, country, and sanctions checks) without exposing private data.

Create a project that uses our onchain verification for disclosure proofs. We are looking for interesting use cases of using the Self onchain SDK in your contracts.
Self Smart contracts verify proofs, manage a merkle tree of identity commitments and allow for onchain disclosure of data while guaranteeing the permissionless aspect of the protocol.
Using the Self.xyz SDK, allows a user to disclose their country, age (or range), that they are not on OFAC or from a sanctioned country, and verify that proof that onchain on the Celo network, or offchain, without sharing any private information with third parties.
Qualification Requirements
To be eligible, projects must:
- implement Self onchain SDK (right now only on Celo mainnet and testnet)
- proof needs to work
