S&P Global Ratings has partnered with Chainlink to bring its stablecoin stability assessments directly onto blockchains, enabling decentralized finance (DeFi) protocols and financial platforms to access real-time risk evaluations.
The new integration uses Chainlink’s DataLink infrastructure, allowing traditional data providers to securely publish information to blockchain networks without developing separate systems. The data feed will initially launch on Base, Coinbase’s Ethereum layer-2 network, with plans to expand based on demand.
S&P’s on‑chain assessments rate 10 major stablecoins, including Tether (USDT), Circle’s USDC, and Sky Protocol’s USDS/DAI, assigning scores from 1 to 5 based on their ability to maintain price stability relative to fiat currencies. The evaluation factors in asset quality, liquidity, redemption mechanisms, regulatory compliance, and governance.
Unlike credit ratings, these assessments focus on a stablecoin’s operational and structural resilience, helping DeFi platforms automatically reference S&P’s data without relying on off‑chain feeds or manual updates.
The move marks a major step toward bridging traditional financial analytics with blockchain transparency, offering developers and investors standardized stability metrics directly within decentralized ecosystems.
