Chainlink Launches On-Chain Stablecoin Ratings

S&P Global Partners with Chainlink for On-Chain Stablecoin Ratings

• S&P Global will provide stablecoin stability ratings on-chain using Chainlink’s DataLink service.
• The initiative launches on Base, an Ethereum layer 2 blockchain incubated by Coinbase, assessing stablecoins like USDT, USDC, USDS, and DAI.
• Stablecoin Stability Assessments (SSAs) evaluate stablecoins on a scale from 1 (very strong) to 5 (weak) based on their ability to maintain value relative to fiat currencies.
• The stablecoin market capitalization has grown to $311 billion by October 2025, up from $173 billion the previous year.
• Chainlink’s infrastructure has facilitated over $25 trillion in transaction value and secured nearly $100 billion in DeFi total value locked.

S&P Global’s collaboration with Chainlink brings Stablecoin Stability Assessments on-chain, enhancing transparency and decision-making within the DeFi landscape. The assessments will initially focus on major stablecoins like USDT and USDC.
