S&P Global is deepening its push into crypto infrastructure through an agreement to acquire OpenZeppelin, a leading blockchain security firm, as financial products and market infrastructure increasingly move onchain. The deal brings smart contract security into S&P Global's growing digital asset business, whose ratings strategy already centers on trusted data, benchmarks, and transparent risk assessment.

S&P Global Adds Smart Contract Security to Its Crypto Strategy

Founded in 2015, OpenZeppelin has become a major security provider for blockchain developers, DeFi protocols, and financial institutions. The company offers open source smart contract libraries, expert security evaluations, and developer services.

According to the companies, infrastructure built on the OpenZeppelin Contracts library has facilitated more than $37 trillion in value transferred. The library is used across a wide range of blockchain applications, including behind many major stablecoins and tokenized funds.

OpenZeppelin has also carried out more than 900 security engagements for digital asset protocols and institutions. Those engagements uncovered more than 10,000 vulnerabilities before production, highlighting the company's role in catching risks before blockchain applications go live. Pre-launch detection carries particular weight in this field because vulnerabilities in smart contract code can be exploited once applications are live.

Security Moves Closer to the Center of Onchain Finance

The purchase places S&P Global directly over a technology-risk layer beneath financial products built with crypto or tokenization.

S&P Global said OpenZeppelin's deeper skill and expertise will augment the firm's existing capabilities in assessing the risk of smart contracts and onchain technology. The combined capabilities can address risks to the blockchain infrastructure and the code underlying an asset, in addition to the financial characteristics of the asset itself.

This is especially relevant for stablecoins, tokenized funds, and DeFi applications, where asset transfers, ownership, and other essential functions are managed by smart contracts. Because those functions run in code rather than through traditional intermediaries, the condition of that code becomes part of the overall risk picture for the products built on it.

"While markets move onto blockchain infrastructure, S&P Global Ratings' digital asset strategy is centered on trusted data, benchmarks and transparent risk assessment," said Yann Le Pallec, the firm's president.

The combination pairs OpenZeppelin's onchain risk assessment and security background with S&P Global's extensive experience in financial-market risk assessment, a fit the companies positioned as natural for crypto markets.

OpenZeppelin Will Continue Under Its Own Name

OpenZeppelin will operate as a standalone business under the S&P Global umbrella and continue to be known as OpenZeppelin. Chief executive Brener will report to Le Pallec.

The parties have not disclosed financial terms for the deal. Closing is subject to customary conditions, and S&P Global indicated that the transaction will not materially affect the companies' finances. With terms undisclosed and closing pending, the next concrete markers are satisfaction of the closing conditions and any further detail from S&P Global on how smart contract risk assessment will be folded into its ratings and data offerings.

The transaction also does not OpenZeppelin's key position in the crypto space, where its security capabilities are already used by blockchain networks, DeFi protocols, institutions, and enterprises.

"OpenZeppelin's standards and technology already allows for infrastructure behind the stablecoins, tokenized funds, DeFi protocols, and other on-chain markets," Brener said. He added that the company would extend this foundation to more organizations entering digital assets, speaking with S&P Global.

The acquisition also gives OpenZeppelin access to S&P Global's institutional relationships and global distribution, potentially bringing its security services and technology to a broader financial-market audience.
