Proof [01]
Proof, not promises.
Two layers stand between a bill and your money. Amigos' checks decide what to pay. The contract that holds the money refuses anything outside your mandate, even if the checks were fooled. Both are tested here, in the open.

51 bills, labelled before the checks ran
Clean bills, changed accounts, look-alike addresses, hidden instructions to the AI, new vendors, duplicates and limits. Each says what Amigos must decide and which red flags they must raise. The labels and the checks were both written by us, so the honest reading is “the rules do what they say”; the reading-accuracy test below is the independent one. Run it yourself with pnpm eval.

The second layer [02]
Even a fooled agent hits a wall.
The mandate lives in the NEAR contract that holds the money. These tests call it the way a tricked agent would. Each refusal names the rule that stopped it. One test checks a real NEAR Intents quote signature, saved from 1click.chaindefuser.com on Nov 3.
Run them: pnpm test:contract
Refused by the contract · 32
- Refuses a vendor not on the list“R1”
- Refuses a new vendor during its waiting period“R2”
- Refuses a quote that pays someone else“different address than the one on file (R2)”
- Refuses a tampered quote“isn't signed by NEAR Intents”
- Refuses a quote that costs too much“fee is above your maximum”
- Refuses a quote for a different amount“doesn't pay the bill amount”
- Refuses to reuse a deposit address“quote was already used”
- A changed address can't be paid before its wait ends“R2”
- Over the auto-pay limit needs approval“R3”
- An approval is for one exact amount“R3”
- Stops at the daily cap“Over the daily cap (R4)”
- Never pays the same invoice twice“R5”
- A resent invoice written differently is the same bill“R5”
- The off switch stops payments“R6”
- The agent can't turn payments back on“Only the owner”
- The agent can't withdraw“Only the owner”
- The agent can't raise its limits“Only the owner”
- The agent can't add a vendor“Only the owner”
- A stranger can't pay“Only the agent or the owner”
- Limits must be in order“auto-pay limit can't be above the daily cap”
- A vendor limit of zero means always ask“R3”
- A vendor limit still counts against the daily cap“R4”
- Duly can't raise a vendor limit“Only the owner”
- A bank payout needs a partner account“aren't set up”
- A new partner account waits 24 hours“partner's account is still in its waiting period”
- A payout can only be recorded for a released bill“hasn't been released”
- A new bank payee waits 24 hours like any address“R2”
- A vendor added after setup still waits“R2”
- The setup key cannot act as owner afterwards“R7”
- Only the owner renames the business“R7”
- Refuses a vendor id with odd characters“vendor id”
- Refuses a colour that is not a hex code“#1f4a3c”
Works as intended · 13
- Pays a NEAR vendor directly
- Pays across chains with a signed quote
- A changed address waits and the old one keeps working
- An approved bill over the limit pays once
- The daily cap resets the next day
- A failed transfer makes the bill payable again
- The owner turns payments back on
- Verifies a real 1Click signature
- A vendor limit lets duly pay that vendor above the general limit
- A bank payout is released to the partner and recorded
- A changed bank payee keeps paying the old one until the wait ends
- Vendors named at setup can be paid right away
- Setup records the owner profile and agent key
On NEAR testnet [03]
The same wall, with real transactions
Amigos' contract is live at duly.harbor-pine.testnet, holding test USDC. On Nov 5, 08:50 UTC the agent paid a clean bill, then its own key tried 9 things a fooled or stolen agent would. Every one was refused. Open any transaction to see the refusal on chain. Run it again with pnpm live:run.

The reading [04]
How well the AI reads bills
Not measured yet
Amigos read bills with a model NEAR AI hosts in sealed hardware, and checks the hardware's signature on every answer. The reading test runs each sample bill five times and scores every field. It needs a NEAR AI Cloud key, which isn't set up yet, so there's no number here. We won't show one until it's real.
What it will report: fields read right, “please check” rate, and whether the hidden “note for the AI” in the scam sample was caught every time.
What this doesn't prove
- That a bill you approve yourself is genuine. Amigos make you call first; they can't make the call for you.
- The live contract runs on NEAR testnet with test USDC. Cross-chain payouts go through NEAR Intents, which only runs on mainnet; they're tested against a saved, real quote signature.
- Bank payouts leave NEAR through a partner. Amounts and limits are enforced; the bank transfer itself is not.
- Our own 51 labels. They test that the rules work, not that the rules are the right ones for every business.
