S&P Global agreed to acquire OpenZeppelin, whose open-source library supported $37T in on-chain transfers and 900+ security audits, expanding its digital asset risk coverage.
Crypto News
S&P Global has agreed to acquire OpenZeppelin, a firm that builds security infrastructure for blockchain-based financial products. The companies confirmed the deal on Sept. 17. No financial terms were disclosed, and the transaction remains subject to standard closing conditions.
OpenZeppelin was founded in 2015. It provides two core services: on-chain security assessments for digital asset protocols and institutions, and an open-source smart contract library used across much of the stablecoin and tokenized fund market. Contracts built using that library have processed more than $37 trillion in cumulative value transfers, a figure that measures historical throughput rather than assets OpenZeppelin holds or manages.
From Rating Issuers to Rating Code
S&P Global has built out its digital asset coverage over the past year. It published stablecoin stability assessments during that time and issued what it described as the first credit rating assigned to a DeFi protocol, Sky. The OpenZeppelin deal extends that work into a layer conventional ratings do not reach: the code that issues, moves, and manages on-chain assets.
A project can have sound reserve backing or a strong credit profile and still be exposed to losses through a flaw in its smart contracts. S&P said banks and asset managers need standardized tools to assess that technical risk before committing capital to on-chain products at scale. S&P Global Ratings President Yann Le Pallec said the deal fits its broader goal of applying trusted data, benchmarks, and risk assessment to markets as they move on-chain.

OpenZeppelin Remains Independent Under S&P
OpenZeppelin has completed more than 900 security engagements, identifying over 10,000 vulnerabilities before code reached production. Co-founder and CEO Demian Brener will remain in charge and will report directly to Le Pallec. The business will continue operating under the OpenZeppelin name as a standalone unit within S&P Global.
The acquisition is part of a broader push by S&P Global into digital asset markets. On Sept. 15, the company led a funding round that brought crypto data firm Kaiko's Series B to $110 million, with BNP Paribas, Nasdaq Ventures, Coinbase Ventures, and Royal Bank of Canada participating alongside it. Earlier in September, S&P Dow Jones Indices and Kaiko launched a co-branded digital asset index suite. In March, the two firms tokenized the iBoxx US Treasuries Index. S&P Global said the OpenZeppelin deal is not expected to have a material impact on its financial results.
