Moody's Tests Credit Ratings Across Blockchains With Chainlink

Chainlink CCIP carried sample Moody’s ratings

Moody’s used its Token Integration Engine to prepare the data for blockchain delivery. Chainlink’s protocol can send messages to software on other networks, a capability distinct from its ability to move tokens. The pilot tested how ratings data could travel between systems that ordinarily keep separate records.

The companies said they used representative data in a controlled setting, without involving Moody’s live publication system. They did not identify the participating test networks or say how many received the data. The announcement also gave no measurements for how long messages took to arrive or what delivery would cost.

An eventual live system could carry changes such as a downgrade. The companies said Moody’s existing publication procedures would govern a production workflow. That would leave the ratings agency responsible for issuing the underlying opinion, with the messaging protocol handling delivery.

Moody’s builds on Canton and Solana deployments

Moody’s started with a node on Canton, where it could connect its ratings system to a network designed for financial institutions. The Solana integration with Alphaledger lets issuers of eligible fixed-income securities choose to attach ratings to their tokenized instruments. It followed a 2025 proof of concept on a Solana test network.

Moody’s said it rated or assessed more than 70 digital issuances between January 2017 and October 2026, including digital bonds and tokenized funds. That figure describes the agency’s work across almost a decade. The announcement did not give a count of securities represented by the sample messages.

Other rating agencies are using blockchain networks to distribute different kinds of research. Chainlink said S&P Global Ratings’ vault risk assessments are live on Base, a public network. S&P designed the assessments to evaluate lending pools that put investors’ deposits to work according to a set strategy. In its October launch announcement, S&P said deposits across such vaults had reached $10 billion in September, up from $1.5 billion two years earlier.

Tokenized bonds still need a live ratings feed

When an investor looks up a tokenized bond, the latest credit opinion may sit in a separate system from the record of ownership. If a live feed reaches the networks where investors hold or trade the bond, portfolio software could read an updated rating without maintaining a separate data connection for every network.

For example, a fund that must hold investment-grade debt could use a current rating to flag a bond for review after a downgrade. That would depend on matching the rating to the correct security, particularly when an issuer has several outstanding bonds with different terms.

A credit rating measures the risk that the borrower fails to pay. Moody’s definition of credit risk excludes factors such as liquidity and price volatility. A rating delivered on a blockchain therefore gives investors the agency’s credit opinion, while the market for the token determines how readily investors can sell it.

Data availability can also differ from trading availability. Chainlink’s Asian stock feeds, for example, follow exchange hours even when a blockchain venue can stay open. For bonds, a live system would need a way for users to tell when a rating was issued and whether the latest update reached their network.

The Crypto Fear & Greed Index rose to 32 on Tuesday from 29 on Monday, remaining in the Fear range.

Moody’s and Chainlink gave no date for a production launch or list of initial issuers. A live deployment would establish which networks receive ratings and how investors can verify they have the current opinion.
