Verifiable real-asset investment.
ZeroH is Blade Labs’ platform for Islamic finance, covered by a Shariah pronouncement from Amanie Advisors dated 23 April 2025. It brings Shariah contracts into the 21st century: the Shariah board approves the structure, every clause becomes an obligation with an owner and a deadline, every step leaves evidence the investor can check, and a Shariah advisor and AI governance come built in. The first contract is live: a cattle-fattening Mudarabah in Bangladesh.

Islamic finance invests in real things. Investors need to see them.
Islamic finance uses different contract structures for financing real economic activity. Mudarabah and Musharakah are partnership structures; Ijarah is a lease. Shariah compliance depends on the terms and implementation of each contract, reviewed by the responsible Shariah board.
It also makes them hard to follow from far away. So we built the platform to show every step of the contract as it happens, with the evidence attached, to the investor, the operator, the Shariah board and the auditor.
From a signed contract to software that keeps it.
The same five steps run for every contract on the platform. Scroll, and follow one contract through them.
01 · Approve
The Shariah board approves
The board checks the structure for riba, gharar and maysir, and sets its conditions, before anything is signed.
02 · Encode
Clauses become obligations
Each clause of the signed contract becomes an obligation: who must do what, by when, with what evidence.
03 · Gate
Gates hold the next step
The software blocks the next stage until a required approval is in. No payout before the board certifies the profit.
04 · Confirm
Both sides confirm
Every payment is recorded by the payer and confirmed by the payee, and every record goes into append-only, tamper-evident storage.
05 · Prove
Everyone sees the proof
The investor’s dashboard, the board’s reviews and the auditor’s report all read the same record, each with the view its role needs.
All five run in the Mudarabah app.

When fuel prices spiked in the region and cow prices fell, the operator asked Ali whether to buy a small herd now and sell it in a few weeks. Ali read the contract, the agreed activity and AAOIFI Shariah Standard 13, and answered in seconds.

Question: Fuel prices spiked and cow prices are falling. Can we buy a small herd now and sell it in a few weeks?
Yes, if you buy them to fatten. A short cycle is fine: the four-month figure was a commercial estimate, not a Shariah rule, and what matters is the husbandry, not the calendar. Stay within the capital and get the investor’s purchase approval (48 hours) first.
Register every cow on ZeroH. Feed it, have the vet check it and manage its weight gain for as long as you keep it, and insure it under takaful.
Keep the full record: purchase weight and condition, feeding logs, vet records, receipts, sale weight and the net gain, with the monthly financial report. That record shows the intent at purchase was fattening, measured as weight gain.
Where it crosses the line: buying and reselling within days, with no feeding or vet care and no weight gain, only because the price moved. That is trading, outside this Mudarabah, and the Mudarib would carry the loss.

Every contract stands on the same foundation.
Each Shariah contract is an arch of its own. They all stand on the same plinth, about a third of any product, which every new contract reuses in full, and under the same roof: Ask Ali and AI governance, built in.
The shared foundation: people and roles, an immutable audit trail, Shariah board workflows, notifications, reporting, and privacy by role, the AI included.
The closer the activity, the more carries over.
Our estimate of how much of the cow-fattening build each new product reuses. Another Mudarabah on livestock is mostly configuration; a lease-based Ijarah on equipment keeps the foundation and adds new contract logic.
Our estimate of reuse per product: cow fattening (Mudarabah) 100%, goat and sheep (Mudarabah) 90%, broiler poultry (Mudarabah) 80%, aquaculture (Mudarabah) 70%, dairy and eggs (Musharakah) 60%, orchards (Musaqah) 45%, crop farming (Muzara’ah or Salam) 45%, equipment and storage (Ijarah or Istisna’) 40%. The shared foundation is 30% of every product. These are estimates from our own build, not delivery dates.
The first contract: cattle fattening in Bangladesh.
Blade Labs invested $100,000 as Rab al-Mal (the capital provider) in a cattle-fattening Mudarabah run by InsureCow as Mudarib (the operator) in Bangladesh, on a 70/30 investor/operator profit split. The contract, with 41 tracked obligations, was signed on 16 March 2026, and the herd of 22 cows is in its fattening phase. The platform is ready to onboard farm operators and institutional investors.
Amanie Advisors issued a Shariah pronouncement on 23 April 2025.
On 23 April 2025 the Shariah Supervisory Board of Amanie Advisors issued a Shariah pronouncement on Blade Labs’ platform for digitalising Islamic financial products and transactions, and found the service compliant with Shariah principles. The pronouncement is subject to an annual Shariah compliance audit.
The pronouncement covers the platform’s method of turning Shariah contracts into enforced software, which the Mudarabah app applies. Each contract on the platform, like the Mudarabah under AAOIFI Shariah Standard 13, is also approved by its own Shariah board before it is signed. The platform pronouncement does not replace the Shariah board’s review and approval of an individual contract.

Islamic finance on ZeroH: common questions
What is the ZeroH Islamic finance platform?
An Islamic fintech platform from Blade Labs, covered by a Shariah pronouncement from Amanie Advisors dated 23 April 2025, that turns a Shariah contract into software that enforces it. The Shariah board approves the structure, each clause becomes an obligation with an owner and a deadline, every payment is confirmed by both parties, and every record is kept in append-only, tamper-evident storage for the investor, the board and the auditor.
Who issued the Shariah pronouncement, and what does it cover?
The Shariah Supervisory Board of Amanie Advisors issued a Shariah pronouncement on 23 April 2025 on Blade Labs’ platform for digitalising Islamic financial products and transactions, finding it compliant with Shariah principles, subject to an annual Shariah compliance audit. The platform pronouncement does not replace the Shariah board’s review and approval of an individual contract. Each contract on the platform needs its own Shariah board approval before signing.
Which contracts can run on the platform?
The first is a cattle-fattening Mudarabah, live since March 2026. The same foundation carries over to other livestock Mudarabah, Musharakah for dairy and eggs, Musaqah for orchards, Muzara’ah or Salam for crops, and Ijarah or Istisna’ for equipment. We estimate the shared foundation at 30% of any product.
How does it keep contracts free of riba, gharar and maysir?
The Shariah board checks the structure for riba (interest), gharar (excessive uncertainty) and maysir (gambling) before signing. Returns come only from real assets, the capital is genuinely at risk, and a gate blocks any payout until the board certifies the profit calculation.
Is it live?
Blade Labs invested $100,000 as Rab al-Mal (the capital provider) in a cattle-fattening Mudarabah run by InsureCow as Mudarib (the operator) in Bangladesh, on a 70/30 investor/operator profit split. The contract, with 41 tracked obligations, was signed on 16 March 2026, and the herd of 22 cows is in its fattening phase. The platform is onboarding farm operators and institutional investors.
What do the Arabic terms mean?
Mudarabah (also spelled Mudaraba) is a partnership in which the Rab al-Mal (also transliterated rabb al-mal) provides the capital and the Mudarib manages the investment activity; profit is shared by an agreed ratio. Shariah (also spelled Sharia) is Islamic law. The SSB is the Shariah Supervisory Board. Takaful is a Shariah-compliant arrangement for mutual protection against specified risks. AAOIFI is the Accounting and Auditing Organization for Islamic Financial Institutions.
