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.

Crypto companies lost over $3.4 billion to hacks in 2025 🚨 The largest losses didn't come from smart contract bugs. They came from compromised credentials, operational failures, and code shipped between audits. While audits are essential, it's clear they're not enough.

Incredible work by @giovannidisiena and @Draiakoo. What they accomplished shows the real impact of security research in blockchain. Their expertise and dedication protected significant value and demonstrated what makes our @cyfrin team special. Proud to work alongside such talented auditors who are making a true difference in web3 security.
Last week I worked with @Draiakoo on a single* mainnet PoC that stole $400k+. Executed across all possible targets, the vulnerability could have easily drained multiple millions of dollars in TVL. While quite (very) stressful at the time, the reality of the situation has only just properly hit me. It’s one thing running forge test but a completely different perspective when you step back to really think about it. We as security researchers are so used to seeing huge numbers without any anchor to reality that it’s all too easy to get caught up in counting fixed point decimals rather than actually deeping the true significance of the amount displayed onscreen. But this is real life, and that really is millions of dollars in value ripe for the taking! Right this second!! Wtf?!!!! A blackhat running the exact same code? Instant payday. They don’t care that it’s 4am and you’re so tired that you can’t type a message straight. You could go to sleep and it could all be gone by the time you wake up. It’s truly wild to think about. I couldn’t have asked for a better teammate in my first experience of a live critical vulnerability disclosure. Big props to @Draiakoo for being an absolute beast! Watching him work can only be described as masterful and I’m excited for us to share the finer details of the attack as soon as possible. A couple million down, here’s to securing multiple millions more in the future! That said, I honestly don’t know how the @_SEAL_Org chads do it. My heart could never. *single root cause but we actually found two different routes to the same attack

🔔 The Bunni team has patched a critical-severity issue found by @cyfrin in an ongoing audit. All funds are safe and no user action is needed. The rebalancing feature has been disabled.
