Moody's Ratings pilots Chainlink tool to publish credit ratings across blockchains

What was tested

Moody's Ratings and Chainlink ran a testnet pilot that distributed the ratings firm's credit ratings data across several blockchains, according to reports from Decrypt and The Block published on 10 November 2026. The pilot used Chainlink's CCIP, which the reports describe as the mechanism for sending data between separate blockchain networks. It ran on a testnet, a test environment rather than a live network.

The pilot covered both permissioned and permissionless blockchains. Permissioned chains restrict who can join and read the data; permissionless, or public, chains are open to anyone. According to Decrypt, the ratings were distributed simultaneously across the blockchains involved, and the arrangement preserved Moody's existing publication and governance processes.

Credit ratings are opinions on the risk that a borrower or an issuer of debt will not pay what it owes. Investors, funds and regulated institutions use them when deciding what to hold.

The Block reported the same core elements: a testnet pilot, the use of CCIP, and distribution across permissioned and public blockchains. Neither report says why the two organizations want ratings available on blockchains, and neither names the chains that took part.

What the reports leave open

Both reports are short, and neither quotes an executive from Moody's Ratings or Chainlink. Neither gives the date the pilot ran, what it cost, or any timeline for wider use.

The reports also do not say what the pilot's results were, or how a rating delivered through CCIP would relate to one published through the firm's usual channels. Whether the work moves beyond a testnet is not stated in either report.
