Kori

The on-chain engine that turns every MetaMask debit card into a true revolving credit card—while merchants get paid in seconds.

1 ▸ Why Kori needs to exist

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.

2 ▸ How Kori works — step-by-step

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.

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.

4 ▸ Why merchants plug in—instantly

Pain with legacy rails

Kori upgrade

Payouts held 7–14 days or more for new sellers

USDC lands the moment the sale clears—no reserves, no rolling holds.

3–4 % card fees + chargebacks

1 % Kori settlement fee, zero fraud chargebacks (Kori owns risk).

Small BNPL tickets (<$400)

Basket sizes climb as users tap expanding Kori lines.

5 ▸ Why users stay

* From debit to credit without leaving self-custody.

* Exportable reputation. Their repayment NFTs form a portable, privacy-preserving credit passport across Web3.

* Rewards that compound. 1 % USDC cash-back auto-stakes into a yield vault, growing future spending power.

6 ▸ Business engine

1. Instant-payout fee — 1 % of every merchant settlement.

2. Interchange share — \~0.6 % on card-rail spend.

3. Credit spread — Borrow at 5 % stablecoin, lend at 12 % APR.

4. Float yield — Idle USDC swept into T-bill–backed on-chain funds.

Tiered exposure keeps expected loss below the BNPL late-payment rate of 41 % reported in 2025 surveys.
