How it works

S&P's OpenZeppelin deal puts a crypto security giant inside the same business that assesses products built with its code.

  • S&P Global said in a Thursday press release it agreed to acquire OpenZeppelin, one of crypto's most widely used smart-contract security companies, as the ratings giant expands deeper into on-chain finance.
  • Financial terms weren't disclosed.
  • OpenZeppelin will remain a separate business unit, while CEO Demian Brener will report to Yann Le Pallec, president of S&P Global Ratings.

S&P already assesses OpenZeppelin-powered stablecoins

That structure creates an unusual overlap. S&P Global Ratings runs Stablecoin Stability Assessments, which evaluate whether stablecoins can maintain their pegs.

  • Its methodology explicitly considers "technology and third-party dependencies" alongside governance, liquidity and other risks.
  • OpenZeppelin, meanwhile, says its contracts are used by USDC, USDe, FDUSD and USDS, among other large stablecoins.
  • S&P has published assessments for all four.

S&P said the acquisition would expand its capabilities into the "onchain technology-risk layer."

"Our digital assets strategy centers on bringing trusted data, benchmarks and transparent risk assessment to markets as they move onchain," Le Pallec said.

The Coinformer reached out to S&P, but the company declined to comment.

The transaction remains subject to closing conditions.
