S&P Global Agrees to Acquire OpenZeppelin in Digital Asset Expansion

S&P Global said on Thursday it has agreed to buy OpenZeppelin, a smart-contract security firm. CoinDesk reported that specific deal terms were not disclosed.

The acquisition extends S&P’s digital-asset risk analysis beyond issuer creditworthiness and reserves. It targets the technology underpinning stablecoins, tokenized funds and decentralized finance products. S&P noted that OpenZeppelin’s library underlies contracts with cumulative transfers exceeding $37 trillion.

“The transaction complements S&P Global's risk assessment and ecosystem development capabilities in digital asset markets, enhancing its ability to create the next generation of onchain security assessments, benchmarks, and deliver essential intelligence as capital markets transition onchain,” the firm said.

Founded in 2015, OpenZeppelin will retain its name and operate as a separate unit. Co-founder and chief executive Demian Brener will lead the business. The firm has completed more than 900 security engagements, identifying over 10,000 vulnerabilities before code reached production.

The deal follows S&P’s earlier strategic stake in crypto data firm Kaiko, which raised that company’s Series B to $110 million. The transaction remains subject to closing conditions and is not expected to significantly affect S&P Global’s financial results.
