PRIVATE BY ARCHITECTURE

Consumer credit that no one can see

A TEE scores your credit privately, collateral earns DeepBook yield, and that yield quietly pays your purchases off — your income, debts, and spending never hit the public ledger.

PRIVATE CREDIT SCORINGTEE // 2x2

Your score, computed in the dark.

An AWS Nitro enclave reads your on-chain history, scores your creditworthiness, and returns a signed result — inputs are Seal-encrypted and never leave the TEE. The score unlocks an under-collateralized line without exposing a thing.

XORR / HOW IT WORKS

Buy Now.
Pay Never.

Lock collateral, let it earn, and let the yield clear your purchases. Your money works instead of being spent — and your finances stay private the whole way through.

01

Get scored privately

Connect your wallet. A TEE enclave scores your credit from on-chain history; the inputs are sealed and never touch the public ledger.

02

Deposit collateral, earn yield

Supply collateral to the XORR pool. It's routed to DeepBook, where it earns the yield that powers the Pay-Never loop.

03

Buy now — the yield pays it off

Make a shielded purchase against your credit line. DeepBook yield auto-repays the balance over time, and you keep your principal.

“Deposit $100, and the protocol fronts your purchase. DeepBook yield streams in to repay it over time — when it’s settled, your principal comes back. You spent nothing.”
