The security standard for onchain finance. $35 trillion+ in value transferred secured since 2015 for the institutions and innovators shaping global finance.

Based in United States
Today we are announcing that S&P Global has entered an agreement to acquire OpenZeppelin. Onchain finance is growing from an emerging market into core financial infrastructure, and the standards and rails our team and community built are becoming the rails of global finance. OpenZeppelin smart contracts facilitated over $37 trillion in value transferred, with the vast majority of the largest DeFi protocols, blockchain networks, stablecoins and tokenized funds relying on them. With S&P Global, we expect to accelerate the impact of onchain finance, backed by more than a century of trust in global markets, benchmarks, and risk frameworks. 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. Building open source standards stays a core priority. • Audits, engineering work, and ecosystem programs continue with the same team, brand, quality, and customer experience, with what will be the added benefit of S&P Global's research capacity, market data, and institutional reach. For the last decade, OpenZeppelin has set the security standard for onchain finance. Today begins a new chapter for that mission, together with one of the most trusted names in global markets.

What does onchain privacy look like? One approach: confidentiality. Amounts and balances stay hidden, while addresses stay visible. The privacy banks and users expect, with the efficiency and security of blockchain. @boyanxyz from @OpenZeppelin explains. stellar.org/blog/developers/…

We co-designed Guardian alongside @0xMiden to solve private-state coordination and recovery without giving up custody. Great to see it behind Bread, a wallet where sending, swapping, and receiving stay off the public chain by default.

MiCA authorization gets you licensed to operate as a CASP in the EU, but it doesn't make you DORA-compliant. DORA has applied to CASPs since Jan 17, 2025. Same ICT risk, incident reporting, and resilience testing rules as banks. Two regimes, one firm, no grace period.

Which of your wallets, bridges, or governance keys would fail first if a quantum computer showed up tomorrow? Every exposed public key onchain is a future liability. A quantum computer could recover the private key behind it and forge authorizations.
