S&P Global has agreed to acquire OpenZeppelin, a smart-contract security firm whose open-source code library underpins much of the stablecoin and tokenized-fund market. The company said contracts built using the library have processed more than $37 trillion in cumulative transfers, though terms of the deal were not disclosed.
The acquisition will broaden S&P’s digital-asset risk analysis beyond issuers’ creditworthiness and reserve quality to cover the technology behind stablecoins, tokenized funds and decentralized finance products. A project may have strong reserves or a solid credit profile yet still fail due to a flaw in its underlying code, the firm said.
OpenZeppelin will retain its name and operate as a separate unit led by co-founder and Chief Executive Demian Brener, reporting to S&P Global. The transaction remains subject to customary closing conditions and is not expected to have a material impact on S&P Global’s financial results.
Founded in 2015, OpenZeppelin provides onchain security assessments and secure development services alongside its widely used open-source smart contract library. S&P said the firm has completed more than 900 security engagements, surfacing over 10,000 vulnerabilities before code reached production.
The move extends S&P’s existing digital-asset work, which has included publishing stablecoin stability assessments and issuing the first credit rating of a DeFi protocol, Sky. The OpenZeppelin acquisition shifts the company’s focus from rating entities to evaluating the code those entities run on.
S&P Global, whose market capitalization is roughly $120 billion, has been building its digital-asset footprint for more than a year. Earlier this month, it led a strategic investment that extended crypto data firm Kaiko’s Series B round to $110 million, with participation from BNP Paribas, Nasdaq Ventures, Coinbase Ventures and the Royal Bank of Canada. In September, S&P Dow Jones Indices and Kaiko launched a co-branded digital asset index suite, and in March the two tokenized the iBoxx U.S. Treasuries Index.
