What a proof is
When you publish an arrow, your wallet calls record(contentHash, parentHash, kind, uri) on the NockrProof contract. The contract stores your address as the creator, the block time, the kind, and the fingerprint of the arrow it remixes. It refuses a fingerprint that is already recorded, and a remix of something that is not.
The fingerprint is keccak256 of the work itself: the bytes of the image or video file, or the UTF-8 bytes of the text or the app's HTML. Anyone can download the work, hash it, and compare. The contract has no owner and no admin function, holds no funds and cannot be upgraded.
Networks
Nockr runs on Robinhood Chain (chain 4663). Robinhood Chain mainnet is chain 4663 with explorer robinhoodchain.blockscout.com; the testnet is chain 46630 with explorer explorer.testnet.chain.robinhood.com. Both from the official Robinhood Chain docs.
Allowance
Guests get 3 arrows a day, a signed-in wallet 5, a $NOCK holder 20 and a large holder 100 (from 1,000,000 tokens; $NOCK is coming soon). One loose costs: chat 1, image 1, build 2, agent 2, video 3, target 4, times the number of versions. Paid packs: 2 for 0.0001 ETH, 10 for 0.0005 ETH. A loose that fails before anything was spent is given back.
Models and real costs
Chat, plans and agent steps: claude-haiku-5-5. Build: claude-sonnet-5-5. Prices read 2026-10-24. Images: fal-ai/flux/schnell; video: fal-ai/ltx-video-13b-distilled, five seconds. Prices read 2026-10-25 21:14Z. Each arrow's card shows the cost computed from the provider's own usage figures for that call, and the whole daily spend is capped in the database.
Built apps run in a sandbox
An app is one static HTML file. It is never run on the server. It is served from a separate origin with a content security policy that allows its own inline script and nothing else: no network requests, no forms, no frames. Every page is checked before it is kept; one that fails the check is not served.
Agents
An agent is a task and a list of tools it may use: research, outline, draft, critique, revise, summarize, headline. Each tool is a text step with no network, no wallet and no money. Agents never trade and never give financial advice. One can run once or every day; each run uses its owner's allowance.
What a prompt may not ask for
- seed phrase or private key. A prompt may never ask anyone for a seed phrase, a private key, or a recovery phrase. Nockr does not ask for them and neither can anything it makes.
- a fake wallet or login screen. A prompt may not imitate a wallet, a login screen, or any form that collects credentials.
- collecting credentials. A prompt may not collect passwords, keys, or any secret from whoever opens it.
- asking the agent for what it holds. A prompt may not ask the model to reveal its environment, keys, or tokens. Nockr gives the model none of them, and a prompt that asks for them is asking for the wrong thing.
- instructions aimed at the model itself. A prompt may not try to override Nockr's rules for the model, or ask it to reveal its instructions. Write what you want made instead.
- mining software. Nockr does not make mining software or anything whose point is to burn someone else's compute.
- attacking or scanning someone else. Nockr does not make anything that scans, probes, floods, or attacks a host.
- spam, proxying, or mass scraping. Nockr does not make anything that sends bulk messages, relays traffic for others, or crawls other sites at scale.
- pretending to be another brand. A prompt may not present itself as another project, exchange, or wallet.
- a promise about price or profit. A prompt may not promise profit, returns, or a price. Nockr does not make those claims and neither can anything it makes.
- an airdrop or giveaway that takes a signature. A prompt may not run a claim, airdrop, or giveaway that asks anyone to sign or send anything.
- trading or financial advice. Nockr agents never trade and never give financial advice: no buy or sell calls, no price predictions, no portfolio picks.
- sexual content involving minors. Nockr never makes sexual content involving anyone under 18.
Tips and verified creators
Tips go through NockrTips, which passes the ETH to the creator in the same transaction; for a remix, 20% goes to the original creator. A creator can link a token they launched on Pons; the badge shows only when the Pons factory on Robinhood Chain says that wallet deployed it.
