How Bidazk works

Buyers fear paying first. Sellers fear delivering first. Escrow ends the standoff.

Bidazk is a reverse marketplace: buyers say what they want and shops bid to supply it. When a bid is accepted, the payment goes into an escrow contract on Stellar. The seller knows the money is real. The buyer knows it only moves when the item arrives.

From request to paid, in four steps

  1. 01

    Buyer posts what they want

    “iPhone 13, 128GB, clean, under ₦520,000, delivered in Uyo within 3 days.” No browsing, no haggling in DMs.

  2. 02

    Shops bid to supply it

    Nearby merchants, or their automated agents, compete on price, delivery time and rating. Bidding costs them nothing.

  3. 03

    Buyer accepts a bid and pays into escrow

    The money leaves the buyer's wallet but does not reach the seller. A smart contract holds it, visible on a public ledger.

  4. 04

    Delivery, then release

    The seller delivers and marks it. The buyer inspects. Confirm, and the seller is paid instantly. The clock covers anyone who goes quiet.

The life of one payment

Every deal is in exactly one of these states. Each arrow is a rule the contract enforces, not a promise we make.

  1. 1Payment heldBuyer paid. Seller must deliver before the deadline.
  2. 2Buyer inspectingSeller marked delivery. Buyer confirms, disputes, or stays silent.
  3. 3DisputedMoney frozen. Only the referee can settle it.
  4. 4SettledSeller paid, buyer refunded, or split. Final. Nothing can reopen it.

What happens when something goes wrong

Escrow is only as good as its edge cases. These are the ones that break trust in Nigerian online trade, and how each one ends.

Buyer protected

Seller never delivers

After the delivery deadline, the buyer gets a full refund. Anyone can trigger it, so it never depends on the seller cooperating.

Buyer protected

Seller runs out of stock

The seller cancels and the buyer is refunded on the spot. No waiting, no support ticket.

Buyer protected

Wrong or damaged item

The buyer disputes during inspection. The money freezes until the Bidazk referee splits it fairly, say 70% back for a cracked screen.

Seller protected

Buyer receives it and goes silent

When the inspection window closes with no dispute, the seller is paid automatically. A silent buyer cannot hold a seller's money hostage.

Seller protected

Buyer cancels while the rider is on the way

Not possible. Before the deadline, only the seller can trigger a refund, so a delivery in progress is never pulled out from under them.

Seller protected

Buyer says “never delivered” after delivery

Once the seller marks delivery, the refund path closes. The only route left is a dispute, which a human referee judges.

Why it runs on Stellar, not in our database

If Bidazk held the money in a company account, you would have to trust Bidazk. On Stellar, you only have to trust the rules, and anyone can read them.

  • Money can only ever go to that deal's buyer or that deal's seller. There is no function that sends it anywhere else.
  • Every deal pays out exactly once. A settled deal rejects every action, so double payments are impossible.
  • Money can never be stuck forever. Whichever side goes silent, the clock settles the deal.
  • Only the buyer can confirm. Only the seller can mark delivery or cancel. Signatures are checked on the ledger, not in our app.
  • The referee can only touch disputed deals, and can only split between that buyer and that seller. Even a stolen referee key cannot pay itself.
  • Bidazk cannot withdraw, freeze or redirect escrowed money. The rules are code on a public ledger, and the contract cannot be quietly upgraded.
