Simpuru runs on Cardano preprod, the test network. Everything is paid in test ADA (tADA), which has no value. Built for the TOKEN2049 Origins Hackathon, Cardano track (agentic commerce).

The short version
Simpuru is a shop for design prompts. A design prompt is a ready-made instruction you paste into a coding agent, and it builds a page: a landing page, a hero section, a pricing table, a 3D scene. Listings come with a recording of what the prompt builds, so you can see the result before you buy. You pay per prompt, not per month. No subscription and no bundle: you buy the one prompt you want for a few tADA, and it is yours to open again whenever you need it. Anyone can sell. If you made a prompt that builds something good, list it, set a price and get paid in tADA every time someone buys it. And you can buy with protection: the money waits in an escrow on Cardano until the prompt arrives. No prompt, or the wrong prompt, and you get your money back automatically.Pay per prompt
Buy one prompt at a time for a few tADA. No subscription, no bundle.
Buy once, open again
A prompt you bought stays yours. Opening it again costs nothing.
Anyone can sell
List a prompt with no approval. Every settled sale builds your public reputation.
Refunded if it never arrives
A protected purchase waits in escrow until the prompt arrives. If it doesn’t, or it’s the wrong one, you’re paid back automatically.
