S&P Global has agreed to acquire OpenZeppelin, a blockchain security company founded in 2015 whose open-source software and security reviews support stablecoins, tokenized assets and decentralized-finance platforms. Financial terms were not disclosed. The transaction remains subject to customary regulatory approvals and closing conditions, and S&P Global said it would not materially affect consolidated financial performance. OpenZeppelin will continue operating independently under founder and CEO Demian Brener, who will report directly to Yann Le Pallec, president of S&P Global Ratings. OpenZeppelin says its code has facilitated more than $37 trillion in cumulative digital-asset transactions and that it has completed more than 900 security reviews, identifying over 10,000 vulnerabilities. The acquisition would extend S&P Global's risk-assessment capabilities into the smart-contract and onchain technology layer. It follows S&P's $110 million stake in crypto market-data provider Kaiko and its broader work on digital-asset indices, tokenized benchmarks, stablecoin assessments and decentralized-finance ratings.
