Smart Contracts

Keyring Network's smart contracts are used to operate different parts of the protocol. Contracts are written in Solidity and released under a BUSL license. Standard contracts leverage the OpenZeppelin Library (version 4.6.0).

See the repository here.

Core Contract

The Keyring Core Contract is a single contract that stores user credentials with expiry and allows blacklisting of entities on a per policy basis. See the repository for full details of the code.
