Darc describes payment cards for AI agents, with owner-set spending rules and a public record of attempted payments, approvals, and refusals.

Landing page captured for the 2026-10-07 issue.

For: Owners setting spending rules for AI agents
Worth noticing: The Atlas example holds a $200 API request and a payment to an unlisted merchant for owner review.

Field notes

The owner sets card rules with a passkey, while the agent signs payment authorizations and a relayer submits them for contract checks. The Atlas example lists Lagos Cloud Hosting and Horizon Data API as permitted merchants, then shows an over-limit API request and an unlisted merchant held for review. The site identifies this demonstration as running on Monad Testnet, so the displayed workflow should not be read as evidence of live mainnet payments.
