Terms of use

Last updated 2026-11-10.

Probarion is non-custodial software in beta. It is unaudited: use it at your own risk. This page is plain language, not legal advice; a lawyer will review it before general availability.

  1. What Probarion is. Software that lets an AI agent pay invoices in USDC inside mandates that the vault's owner signs. A NEAR contract checks every payment, and the vault's owner can publish the signed ledger for anyone to verify.
  2. It does not hold your funds. Your USDC stays in your own vault contract. Only your wallet can withdraw it, change its keys or unfreeze it. Probarion keeps no owner key.
  3. Unaudited beta. No third party has audited this code. Use small amounts.
  4. Testnet today. The vault runs on NEAR testnet with test tokens. One small mainnet vault, made by no factory, has run since 2026-11-11, and no Base payout has run on mainnet.
  5. At your own risk. The software is provided as is, without warranty of any kind, under the MIT license. You decide what your mandates allow, and you are responsible for the payments they permit.
  6. Liability. To the extent the law allows, we are not liable for losses from on-chain transactions that you or your agent made within the mandates you signed.
  7. You sign. Every transaction that creates, funds or configures a vault is signed by you, in your own wallet.
  8. Payments are final. A payment on chain cannot be reversed. Check every payee address before you sign a mandate.
  9. The agent key. The agent key Probarion keeps for your vault can call spend only, inside the mandates you signed. You can remove it, or freeze the vault, from your wallet at any time.
  10. Third-party services. NEAR, NEAR Intents and its bridges, NEAR AI Cloud, 1Click and your wallet are run by others. We do not control them or their fees.
  11. Lawful use. Use Probarion lawfully. Sanctions, tax and accounting rules where you operate are your responsibility. Do not use it to pay for anything illegal.
  12. No fee. Probarion charges nothing for the console. Your wallet pays the NEAR network's fees and the deposits that pay for a vault's storage: when you create the vault, and for each mandate.
  13. Fair use. Do not attack other people's vaults or overload the service. The Canary is the one vault open to attacks, under its own rules. Canary rules
  14. Not legal advice. This page is plain language, not legal advice. A lawyer reviews it before general availability. When these terms change, the date at the top changes with them, and the repository keeps every earlier version.
