Every agent stops at the same spot: money moving. Tiba reads the bill against your own record, pays only when they match, and refuses — with a receipt — when they don't.
Write the job in plain English. Tiba drafts the scope, budget and expiry. You review it, then sign.

Once agents pay bills, the bill itself becomes the attack. Tiba reads the bill and your own record in two separate checks, and the check that reads your record is never shown the bill. The amount paid always comes from your record. If the bill names a different job, Tiba refuses.

Paid or refused, the receipt says who asked, which rule allowed it, and what happened on Solana.

A ceiling per payment, hourly and daily limits, saved recipients only, and a freeze switch. Big payments still come back to you.

Communities and grant programs that pay contributors and bounties — starting with Superteam Malaysia and the KrackedDevs crowd. An agent pays a contributor; Tiba reads the claim against the bounty and the record, pays or refuses, leaves a receipt either way.
Card payments have 3DS, a check before the money moves. Agents get spending limits. Of the 18 we compared as of 25 Sep 2026, none offered both a bill check and a public receipt for a refusal. Tiba is that check, on any rail, for any payer and any bill, not one supply chain. Live on Solana's test network. Next: three outside teams from the Superteam Malaysia and KrackedDevs crowd, each with a public receipt and a refusal.
