BUREAU
Instant onchain uncollateralized LOAN for AMEX users

BUREAU is a decentralized identity + credit engine that enables instant, uncollateralized stablecoin loans onchain, exclusively for verified AMEX cardholders.

By combining zk-based verifications (via TLS Notary and zkPassport) and MOCA-compliant Verifiable Credentials, BUREAU creaates and also allows DeFi protocols to trust offchain creditworthiness in a fully private and composable way.

How it works:

1. User submits proofs (passport nationality, AMEX statement, and no debt).

2. The system can issue 3 VCs (Verifiable Credentials):

   • ✅ AMEX Activity VC: no outstanding debt.

   • ✅ KYC VC: U.S. Citizen.

   • ✅ Credit Score VC (1–10 scale).

3. These VCs are validated onchain using zk and stored privately.

4. User requests a loan from a liquidity pool (funded by yield-seeking providers).

5. No collateral is needed, trust is based on the user’s verified identity & AMEX behavior.

For Liquidity Providers:

• Deposit funds with configurable yield & lock time.

• Loans are split proportionally across multiple pools.

• Capital is repaid automatically as the borrower repays — with a built-in 0.5% fee to the BUREAU protocol.

Smart Contract Core:

• depositLiquidity(): fund yield-bearing pools.

• requestLoan(): permissionless loans based on VCs.

• payLoan() / payDebt(): manages repayment and late penalties (up to 80% APY cap).

• withdraw(): reclaim liquidity when unlocked.

Use Case:

We unlock $1.2T in potential onchain credit by tapping the AMEX user base, the same trusted users that traditional finance already recognizes. This allows DeFi to mirror TradFi trust, without compromising privacy or requiring collateral.
