Take back the say
in what you spend.

A price isn't a number. It's a stack. The product is at the bottom. Above it sit VAT, retail margins, brand premiums, import costs — and most of that stack is invisible by the time you tap your card. Yumo Yumo reads the receipt, peels the stack apart, and turns the part that sits on top of the product into a token. Hold it. Cash it out. Trade it on DeFi.

01 — The unseen economy

Every day, billions of tiny receipts change hands and vanish.

300B+
Paper receipts printed worldwide every year. Most live less than an hour.

Of that data, the person who actually paid gets to keep, query, or earn from — this much.
Status quo
3.2x
Price spread for the same product across stores in one city. Most shoppers never see it.

02 — Proof of expense

A receipt is already a signed document. We just teach the world to read it.

01 · CAPTURE
A photo of paper
Snap the receipt — paper, PDF, mobile order, e-invoice. Whichever form the expense showed up in.
02 · UNDERSTAND
Read it. Prove it.
OCR finds the text. A language model finds the meaning. A regex checks the math. Three witnesses, one record.

The stack, taken apart
A price is never just the product. It carries VAT, retail margin, brand premium, import. We pull the receipt apart layer by layer, show you what each one cost, and mint a token tied to the share you paid above the product itself.

04 — The loop

Every proof feeds the system. The system returns the layers.

U
User
Uploads a receipt. Sees what's stacked on top of the product. Owns the proof.
D
Data
Parsed, anonymised, aggregated. The economy gets readable.
T
Token
Sized to the share above the product. Convert it. Trade it on DeFi.
P
Proof
Non-transferable. Only the owner can query it.

The other apps work like this: a brand pays, you get points, the data leaves with the platform. You were the product.

Yumo Yumo flips it. You're the witness. The receipt stops being a coupon and becomes a price broken into its real layers — product, VAT, retail margin, brand premium.

The part that lands on top of the product is the hidden cost. We surface it, prove it, mint a token that carries its weight.

That token is yours. Hold it. Cash it out. Trade it on DeFi. The reward is no longer a coupon — it's an asset, and it moves with you.

05 — The horizon

By 2031, every price in the world is one click away. The economy is decentralised. The black box is open.

2026Now
Live. Six languages, multi-currency.
The receipt pipeline runs end-to-end. The product is in public beta — anyone can test, mint proofs, see prices across merchants, and earn against their hidden cost. Six languages and multi-currency normalisation are already in the system.
2027Next
The protocol opens.
Beta becomes origin version. Yumo Yumo's proof layer is published as an open standard — other apps can issue proofs against the same canonical product graph. The user keeps a single, portable economic identity.
2029In three years
A new kind of statistic.
National statistical offices begin referencing Yumo Yumo aggregates alongside their own CPI baskets. Real-time, household-scale, k-anonymous. Price truth stops being a quarterly story.
2031In five years
Every price, one click away.
The world's prices are freely reachable. The economy is decentralised and fully transparent. People reach this data not only to manage their personal finance — but to grow their businesses, find their margins, and build on data that used to belong to no one. Twenty plus languages, every major currency.
