The rules, as the platform enforces them

• One account per person, identified by a phone number. It is yours and you are responsible for what is done with it.
• Verification is tiered. You are only asked for what the thing you are doing requires — looking at prices needs nothing but a phone number.
• Repeated failed sign-ins lock an account temporarily. It clears by itself and the message says when.
• Presenting a session token that has already been used revokes every session on the account, on every device. That is a defence against a stolen token, and it is deliberate.

• The weight you declare when booking and the weight the scale reads at the hub are both kept. You are paid on the scale reading.
• A reading far away from your declaration is refused until the agent confirms it — a mistyped digit and a genuinely short load look identical to software.
• A weight recorded in error can be corrected, and every correction keeps the old figure, the new one, who made it and why, permanently.
• A lot is graded once. A second opinion is a new lot — re-grading would leave a receipt pointing at a grade that no longer exists.

A receipt is a claim on stored produce, and it is treated as a financial instrument rather than a document.

• It is issued from a grading automatically, to the farmer who grew the produce — never to the aggregator who carried it.
• A receipt pledged as loan collateral cannot be sold. The grain is already promised, and the register exists to stop it being promised twice.
• A receipt that has been pledged or sold cannot have its quantity restated, even to fix a genuine error. Somebody else has relied on it, and that has to be resolved with them rather than around them.

• Fees are charged on the gross value of a settled trade and taken out of the seller’s proceeds. Registering, booking and grading are free.
• A buyer funds a wallet before buying. Accepting a listing agrees a contract immediately and settlement resolves a moment later; if the funds are not there the contract is rejected and the listing reopens.
• Money committed to a trade is held in escrow and shown separately from your balance. It is yours, and it cannot be spent twice.
• Every movement is double-entry. The platform clearing account nets to zero, which is what makes a disputed figure checkable rather than arguable.

Said here so nobody plans around it. The exchange order book is not open. No mobile money rail is connected, so a withdrawal reserves your funds and marks them for dispatch — the money has not left the platform, and the screen says so before you commit rather than after. Automated quality grading does not exist; every grading is done by a person.

Ask us. If something here does not match what the platform did, that is a fault worth reporting and we want to know.
