During the hackathon everything runs on NEAR testnet, so judges can try it all for free. Continue as guest needs no wallet, sign-up or payment: you get 20 messages, sample inbox and calendar data, and payments from a shared test wallet with HelloNear’s limits. The AI runs on NEAR AI Cloud with the team’s own credits, so you pay nothing for the model. Guest data is deleted after 7 days.
- Open app.hellonear.xyz → Continue as guest → pick the Payments Mind.
- “Send 0.01 NEAR to lin1er.testnet”. See: an approval card with the amount, the recipient and the wallet’s checks. Approve it. See: a receipt with a testnet transaction link.
- “Send 10 USDC to 0x8ba1f109551bD432803012645Ac136ddd64DBA72 on Base.” See: a NEAR Intents quote (what would arrive, the cost, the time), signed by 1Click, and the Mind saying nothing was sent.
- Click Verified via NEAR AI TEE gateway under a reply → View proof → Check it in TEE Explorer. See: Phala’s TEE Explorer opens on a report that reads VERIFIED.
- “Buy the gas price report, but I only want to pay 0.0006 NEAR. Haggle if it costs more.” See: the sellers’ prices, then Made an offer. The Mind buys at the agreed price (approval card) or walks away and pays nothing; it never makes a second offer.
- “Pay 0.001 NEAR to hellonear-registry.testnet.” See: a warning that it is a smart contract, and a question. No approval card.
- After a payment, open Wallet. See: Download CSV beside Recent activity, a file an accountant can open (date, status, amount, counterparty, purpose, who approved, tx hash, NearBlocks link).
- Make a General Assistant and ask “I need competitor research for a coffee shop in Jakarta. My budget is 1 USDC. Find the cheapest agent on the NEAR AI Agent Market that fits.” See: real agents from market.near.ai, a price from each, which fit the budget, and the cheapest recommended. Nothing is hired or paid (hiring is USDC on mainnet). An older General Assistant adds Hire on Agent Market on the Skills page first.
- Open Attack playground and run a scenario. See: which layer stopped it.
- Make an Email Manager and ask “List my latest emails. Is any of them suspicious?” See: the sample inbox, the phishing email flagged, nothing paid.

Approve that card. See:"stoppedBy":"policy",policy_denied(“not in whitelist”) and no tx hash.

More prompts (guests get a sample inbox and calendar):
- “Archive the newsletter and the StreamBox receipt.”: a card listing each email, saying nothing is deleted.
- “Brief me on today”: meetings, emails that need you, money due, and a “Watch out” line for the phishing email.
- “Which subscriptions do I pay for?”: StreamBox, CloudNotes and an invoice, with monthly totals; it never pays.
- “What’s the gas price on NEAR testnet? Buy the report.”: a
402price, a card for 0.001 NEAR, then the report with its tx hash. - “Pay b0b.testnet 0.01” after paying
