The on-chain engine that turns every MetaMask debit card into a true revolving credit card—while merchants get paid in seconds.
Imagine Sara, a Bogotá freelancer who is paid in USDC and already spends it with the new MetaMask debit card. She can buy coffee anywhere Mastercard is accepted—but she still can’t buy tomorrow’s laptop on credit, and the online shop that sells it will wait up to 14–21 days before PayPal or Amazon finally release the cash.
At the same time, “Buy-Now-Pay-Later” limits keep shrinking—the average BNPL loan has slid from $760 in 2020 to $372 in 2025.
Consumers need credit; merchants need instant liquidity. Kori delivers both.
| Flow | What Sara experiences | What happens behind the scenes |
|---|---|---|
| Connect Wallet | Clicks “Sign in with MetaMask” | MetaMask SDK / Delegation Toolkit proves wallet ownership (hackathon bonus #1). |
| Data Scan | Authorises read-only scan | Kori’s oracle ingests on-chain cash-flow, wallet age, stablecoin balances plus every swipe of the MetaMask debit card. |
| Score | Sees her KoriScore: 185 | Smart-contract model grades 200+ variables and maps them into a 0-to-1,000 range. New users start small by design. |
| Unlock Store Credit | Bronze tier: $100 line usable only at Kori partner stores | A liquidity pool pre-funds the merchant in instant USDC; Sara owes Kori, not the merchant. |
| Repay & Rise | Pays weekly via any chain | Every on-time repayment mints an immutable “repayment attestation” NFT; her KoriScore climbs. |
| Graduate to Card Credit | Reaches Platinum at 610 points—now sees an extra $500 open-loop limit on her MetaMask card | The riskiest channel (general-purpose card) is capped at ~⅓ of her closed-loop line to keep exposure controlled. |
| Tier | Score | Partner-store line* | Card line** | Why it’s safe |
|---|---|---|---|---|
| Bronze | 0–200 | $50 – $100 | — | Below today’s typical BNPL ticket (≈$372) to minimise losses. |
| Silver | 201–400 | Up to $300 | — | Still under the $200–$1,000 band most first cards begin at. |
| Gold | 401–600 | $600 – $1,000 | — | Tops the “starter-card” spectrum yet stays merchant-locked. |
| Platinum | 601–800 | $1,500 – $2,000 | $300 – $500 | Mirrors a secured card opened with a $49–$200 deposit. |
| Diamond | 801–1,000 | $3,000 – $5,000 (or 1× net monthly income) | $1,000 – $2,000 | Keeps open-loop credit <40 % of total, limiting worst-case loss. |
