Union Protocol
Union is an open-source peer-to-peer credit protocol on Ethereum, Optimism, Base, and Arbitrum where users vouch for each other to access uncollateralized loans.

What is Union Protocol?
Union is a decentralized credit protocol where users underwrite each other onchain. Stakers deposit stablecoins, vouch for trusted contacts, and earn UNION when those contacts borrow. Borrowers draw against vouches to access uncollateralized credit lines without a credit score or collateral, and UNION holders govern rates and parameters through onchain voting.
