Credit score and Shariah screen

Engine · lexicon + credit score

The Karma engine scores open-banking cash flow, device signals and a Shariah lexicon/semantic screen. It does not forecast liquidity fourteen days ahead. The twenty-two-step line belongs to a separate quant feed and is not this product.

Basket screen

Baskets pass a lexicon, a semantic filter and optional System-1. Non-compliant items never receive an originate packet.

Late payments and limits

Late installments do not accrue interest. Late counts lower the limit. Contractual gharamah is defined and closed in the product.

Ecosystem history

Where consent is given, Karma cash and installment history enter the score. Income verification sets the ceiling.

Financial discipline

“On-time performance is recorded. That is not an automatic limit raise or a principal guarantee.”

Profit follows liability, and the sale price is known when the contract is made.

Liquidity commitments

Share token: vMDB

Providers deposit into the vault and receive shares of the pool. Early bands and lock length change a rebate weight. They are not a promised return.

Non-Reopening Cold-Start Multipliers

One-Time Genesis Window · Closes Permanently

The 5x (Diamond), 3x (Gold), and 2x (Silver) multipliers apply exclusively to the initial $5,000,000 in committed liquidity. The counter never rolls back, even after commitments mature and capital is redeemed. All subsequent allocations permanently enter at the 1x Bronze baseline. Your total rebate weight = Genesis Multiplier × Lock Term Weight (e.g. 5x × 1.0x = 5.0x max).

Compound Formula:Effective Weight = Tranche Multiplier × Term Weight(e.g. Diamond 5x × 12m 1.0x = 5.0x Maximum Weight)

Investor console and liquidity

How portfolios are managed today

Retail and institutional exits follow the vault and gateway that are actually shipped. There is no licensed bank off-ramp, no named MPC custodian, and no hardware quorum in this release.

Retail: vault shares and a queued redeem

ERC-4626 · FIFO queue · no bank wire

Step 01

Account access

Retail Karma sessions use the checkout identity already on the product. A seedless Face ID bank login is not part of this release.

Session identity

Step 02

Portfolio figures

Share value and pool totals come from protocol telemetry. Design-band weights are labelled as configuration, not as a live yield.

Telemetry

Step 03

Redeem request

A redeem is a vault request. If cash is not sitting in the vault, the request joins the FIFO queue as receivables settle.

FIFO queue

Step 04

Settlement rail

There is no licensed Turkish FAST payout to a named domestic bank in this product. Fiat off-ramp partners are not contracted.

No regulated MPC custody partner is in use. Operator roles and contract pause exist in code. A multi-sig policy is not bound to a custody contract yet.

Institutional Custody & Smart Contract Defense

How Institutional Capital is Safeguarded: The 5-Layer Anti-Hack Matrix

MudarabahVault.sol · Non-CustodialOpenZeppelin libraries; independent audit planned

Pool capital sits in the non-custodial MudarabahVault. No regulated MPC custody partner is in use. Contract pause exists for operator and oracle divergence. An independent audit is planned.

Non-custodial vault

Q: Can Karma or ShariaCo operators arbitrarily withdraw and drain pool assets?

No admin drain

MudarabahVault has no function for operators to send capital to an arbitrary address. That is not a substitute for an independent audit.

Capital can ONLY exit the vault upon the generation of a verified MurabahaNFT trade note and direct settlement to authenticated physical goods suppliers. Even protocol architects cannot divert funds.

Risk & Downside Protection Matrix

Traditional DeFi Risk vs. ShariaCo Institutional Architecture

Addressing the 5 critical security questions evaluated by LP Treasuries and CFOs:

Attack / Risk Vector	Conventional Crypto / DeFi	ShariaCo Institutional Matrix
Operator Rug-Pull / Insider Drain	✕High Risk — Admin private keys can drain liquidity pools	✓Non-custodial vault — no admin drain function; independent audit planned.
Single Private Key Theft	✕Critical Risk — Compromise of one key results in total loss	✓No custody partner; pause exists on the contract.
Flash-Loan & Exploit Loops	✕Prevalent — Billions lost in unaudited smart contracts	✓OpenZeppelin libraries; independent audit planned.
Market Flash-Crash & Oracle Drift	✕Severe Loss — Cascading liquidations dissolve capital	✓Contract pause on operator or oracle divergence; no millisecond SLA.
Counterparty Default & Loss	✕100% Absorbed by Investor — Zero remediation layer	✓Takaful is defined on the contract and closed in the product. There is no principal guarantee.
