Builder story
nimSeal grew out of a simple frustration: getting paid in crypto meant either exposing an entire invoice on a public ledger or accepting a bare transfer with no protection. I rebuilt an earlier confidential‑escrow experiment as a Nimiq Pay Mini App — keeping terms encrypted off‑chain, adding a Nimiq‑wallet seal that buyers verify client‑side, and settling in USDT through an on‑chain escrow. Mobile‑first, no extension, no seed phrase.
