OpenZeppelin

OpenZeppelin is now officially a part of S&P Global.

The acquisition we announced in September is finalized. OpenZeppelin’s decade of securing and building the infrastructure onchain finance runs on now meets @SPGlobal's more than a century of helping markets understand risk. Together, we can help institutions and builders move onchain with greater confidence.

To our clients and to all the users of OpenZeppelin open source tools:
• OpenZeppelin Contracts and all our open source applications and tools remain open source, free and publicly maintained on GitHub.
• Security audits, secure development work and ecosystem programs continue with the same team, brand, quality and customer experience, now backed by S&P Global’s research capacity, market data and institutional reach.

For the last decade, OpenZeppelin has set the security standard for onchain finance. Now we take it to the scale of global finance.
