S&P Global has agreed to acquire OpenZeppelin, a smart contract security firm whose OpenZeppelin Contracts library has supported contracts through which more than $37 trillion has moved. The library provides standard token and contract implementations used by the vast majority of major stablecoins and tokenized funds. OpenZeppelin, founded in 2015, will operate under its own name as a standalone S&P Global business unit, with CEO Demian Brener continuing to lead and reporting to Yann Le Pallec, President of S&P Global Ratings. The company has completed more than 900 security engagements, including a late-2021 review that identified a bug placing $15 billion in Convex Finance deposits at risk before it was patched. Financial terms were not disclosed, and S&P Global said the transaction is not expected to materially affect its financial results. The deal comes as institutional interest in tokenization and onchain markets grows. S&P Dow Jones Indices has offered crypto benchmarks since 2021, while the U.S. Securities and Exchange Commission opened the door the same day to secondary trading of tokenized U.S. stocks under a temporary innovation exemption requiring publicly auditable smart contracts on public, permissionless blockchains.
