PROVENIM
Before a merchant fulfils an order, Provenim proves the NIM payment that is supposed to pay for it.
About
Provenim verifies NIM payments against real Nimiq Testnet evidence, binding each payment to its intended transaction and producing tamper-evident receipts that anyone can independently verify.

Builder story
Building Provenim started with a question: what should “paid” actually mean?
Most payment experiences stop at a wallet callback, a database flag, or a transaction appearing somewhere in account history. For a merchant, however, the real question is much simpler and more consequential: can I safely fulfil this order?
I built Provenim by starting from Nimiq’s infrastructure rather than from a generic payments UI. The discovery was that payment attribution can span different transaction and account representations, making a naive “I found a payment” check insufficient.
So Provenim turns payment into a verifiable claim.
