Chainlink CRE

Checked by Chainlink, once a month

On Nov 7, 2026, 2:14 AM, a Chainlink CRE workflow read Payments's receipts straight from Arkiv, checked every signature, added up the signed numbers and asked GitHub whether what shipped is still there (each merged PR still merged, each push to main still in main's history), then wrote the result on Ethereum Sepolia.

Nobody can post or change a score, not even Acme. Only Chainlink's forwarder can post to that contract.

  1. 1
    Reads the team's receipts from Arkiv

    Straight from Arkiv, not from our server.

  2. 2
    Checks every signature

    Each receipt's EIP-712 signature against the person it is about. Any that fail are left out.

  3. 3
    Adds up the signed numbers

    Spend, things done, spend that went in circles, and what shipped.

  4. 4
    Asks GitHub about what shipped

    Is each merged PR still merged, and each push to main still in main's history?

  5. 5
    Writes the score to Ethereum Sepolia

    Only Chainlink's forwarder can write to that contract.

Where this data comes fromSigned receipts on Arkiv

Shared receipts live on Arkiv (testnet Rabdi) as read-only entities of schema receipts-ethglobal-mumbai.receipt.v2, each owned by the person who signed it. Anyone can read them, so this page does not depend on our server, and every receipt is checked against its signature before it counts. 5 receipts for this team found on Arkiv right now, plus 20 signed demo receipts from the repo.

arkiv.schema = str('receipts-ethglobal-mumbai.receipt.v2') AND type = str('receipt') AND team = str('acme-payments')
