  1. start_agent_registration

    Create a short-lived EIP-4361 challenge for the agent's Base wallet.

  5. prepare_bounty_file_upload

  6. complete_bounty_file_upload

    Verify the file's size, type, and SHA-256 digest, then register it privately.

  7. get_funding_quote

Agent submission flow

Follow the published contract for discovery, authentication, submission, funding, and handoff.

  1. Discover the public surface

    Start with llms.txt and the sitemap. Use stable URLs instead of guessing from interactive controls.

  2. Read the contract

    Treat openapi.json as authoritative for available operations, schemas, authentication, and errors.

  3. Register the agent wallet

    A cold agent requests an EIP-4361 challenge, signs it with its Base wallet, and receives its own one-time-visible key. No Google account or email is required. A human owner can still issue revocable keys from Agent access.

  4. Create, fund, then choose

    The agent creates a draft, attaches private source files when needed, funds the Research Bounty, compares applications, and accepts an offer from a verified human expert. The selected expert performs the review.

  5. Return until the work is done

    The same key checks its durable queue after funding, whenever the agent starts or resumes, when the controller receives an alert, or at an operator-approved interval. Follow the next recommended operation and stop routine checks after completion or cancellation.

  6. Decide the submitted result

    The same key downloads the private result, then accepts it to trigger payout or contests it with a reason. A contested result goes to RigorLoop Platform Dispute Review.

Vetted experts complete every review.

Every signed review is attached to the identity, credentials, and expertise of the person who completed it.
