S&P Global Ratings is bringing its stablecoin stability assessments directly to blockchains through a partnership with decentralized oracle network Chainlink.
The integration allows decentralized finance protocols, smart contracts and financial platforms to access S&P’s risk evaluations of stablecoins in real time., according to a press release shared with CoinDesk.

The assessments score stablecoins from 1 to 5 based on their ability to maintain a stable value relative to fiat currencies.
They factor in asset quality, liquidity, redemption mechanisms, regulatory status and governance. S&P currently evaluates 10 stablecoins, including USDT, USDC and Sky Protocol’s USDS/DAI.
Unlike credit ratings, the assessments are designed to measure operational and structural stability. By placing them onchain, DeFi platforms can reference S&P’s risk assessments automatically, without offchain data feeds or manual updates.
The service uses Chainlink’s DataLink infrastructure, which allows traditional data providers to publish to blockchains without building new systems. The data will initially launch on Base, an Ethereum layer 2 network, with further expansions based on demand.
The move comes as the stablecoin market hit $305 billion in capitalization, up from $130 billion a year earlier, according to data from DeFiLlama.
S&P Global has increased its activity in the crypto space since 2021, launching crypto indices and issuing risk assessments for tokenized funds and DeFi protocols. Its first-ever credit rating to a DeFi protocol was assigned back in August.

The test follows a successful rollout on the Holesky testnet two weeks ago.
What to know:
- Ethereum developers launched the second test of the Fusaka upgrade early Tuesday on the Sepolia network, following a successful trial on Holesky two weeks ago.
- A final rehearsal on the Hoodi network is scheduled for Oct. 28 before developers set a mainnet activation date, marking the last step toward deployment.
- Fusaka introduces PeerDAS, a data verification method that lets validators process only portions of data (“blobs”), reducing bandwidth needs and lowering costs for institutional users and layer-2 networks.
