Locked in a smart contract until delivery

Your USDC is locked in a smart contract, not sent to us. The contract lets us collect it only if we deliver within 14 days of your payment (by 16 Nov 2026 if you pay today). After that date, if we have not collected it, you take it back yourself from My apps, no permission needed. Before it, only we can refund: if we miss the promised date, ask in My apps and we refund you from the contract. View the contract on BaseScan. This covers every payment, a reservation too: the funds are released to us only when we deliver.

Promised delivery: 9 Nov 2026 (counted from payment). Self-refund opens: 16 Nov 2026 (the contract deadline).

Picture this

Who it is for

Maricela Ochoa is the treasurer of a 38 member fishing cooperative in San Felipe, Baja California. The buyer from Ensenada pays the co-op days after the boats come in, so members wait a week for cash in envelopes and never see the price the co-op got. Weigh Day records each panga's catch at the dock scale on a weigh slip that the weigher and the member both sign, shows the buyer's price per kilo and the co-op's 8 percent cut on the slip, and pays every member in USDC on Stellar or Celo the same afternoon from the co-op's float. Members cash out at a nearby MoneyGram access point or keep it as dollars, and anyone in the co-op can check the public ledger.

Why it is new

What exists today, and what this does differently

What is new

Farm and fishery payment tools exist (mobile money payouts, agritech platforms that pay farmers by phone), and Stellar has proven cash out through MoneyGram. What is new is the open slip: every weigh slip carries the buyer's price and the co-op's cut, both people sign it, the co-op pays from its own float the same day, and the whole co-op can read one ledger of what was sold, what was kept and what was paid.

Closest things out there

Agritech payout platforms such as Farmerline and mobile money bulk payouts pay farmers by phone. MoneyGram Access on Stellar offers USDC cash in and cash out. Kotani Pay and similar services bridge stablecoins to mobile money. None publish the buyer price and the co-op cut on a slip both sides sign.

Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.

What it unlocks

The human in it

The people who do the hardest work in the supply chain finally see what their catch sold for, what the co-op kept, and get paid the day they worked.

BLUEPRINT

Why it matters and how it really works

The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.

The need

Small fishing and farming cooperatives sell their members' catch or harvest to a buyer, take a cut for the dock, the ice and the scale, and pay members later. Members often wait days or weeks, get paid in cash envelopes, and never see the price the buyer paid. Disputes over weights and cuts strain the trust a cooperative depends on.

What exists and what is new

Producer payouts exist: agritech platforms and mobile money bulk payments pay farmers by phone, and MoneyGram Access on Stellar lets people cash USDC in and out. Weigh Day is an incremental take with one new rule: every weigh slip shows the buyer's price per kilo and the co-op's cut, the weigher and the member both sign it, and the member is paid in USDC the same day from the co-op's float. The co-op's ledger of sold, kept and paid is open to every member. Research verdict: payouts exist; the open, two signature slip with same day payment is new, medium novelty.

The data it runs on

Unlocked when your app is paid in full

1.The mission

The people who catch and grow the food should see what it sold for, what their co-op kept, and get paid the day they worked.

2.Why people can't resist it

The open slip Every slip shows the buyer's price, the co-op's cut and the member's share in plain numbers. Nothing about the money is hidden from the person who did the work.

Paid before the boat is washed Signed slips are paid in USDC the same afternoon from the co-op's float. The co-op waits for the buyer; the member does not.

One ledger for everyone Any member can open the co-op ledger and see what was sold this month, what the co-op kept and what was paid out.

8.Where this is going

  1. Now
    One cooperative, one dock scale, signed slips and members paid the same day.
  2. Next
    Buyer statements, Spanish and Swahili slips, and federations that see all their co-ops in one place.
  3. Later
    Buyers can pay the co-op directly on Stellar or Celo the moment a load is accepted, so the float is needed less.
  4. The world it builds
    Producers everywhere see the price of their own work and are paid for it the day they do it.

Why own Weigh Day

Small cooperatives feed whole towns, and their members are often the last to be paid and the last to know the price. Owning Weigh Day means you run the open version: a weigh slip both people sign with the buyer's price and the co-op's cut on it, members paid in USDC the same day on Stellar or Celo, and a ledger every member can read. You earn from co-op plans, never from a member's payout.

What’s stopping you?

“Cooperatives are slow to change. Will they ever switch?”

Weigh Day keeps their routine: the same scale, the same weigher, the same buyer. It only adds a slip both sides sign and a faster payout. Start with one co-op whose treasurer is tired of counting envelopes.

“What if a buyer pays late and the float is empty?”

The app shows the gap before anyone is paid, pays in slip order and records the rest as owed. It never marks a slip paid that was not paid, so trust survives a late buyer.

“Can members really turn USDC into cash?”

In many places, yes, through MoneyGram access points that work with USDC on Stellar or Celo wallets linked to mobile money. Your copy lists only points the co-op has checked, with their fees, and members can always keep dollars.

“Two chains and smart contracts sound like a lot.”

Your copy ships with the Soroban contract and the Celo contract deployed by DEPLOYR. Most co-ops use one chain. Leave the other off until a co-op asks.
