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.

Monitoring changes outcomes. Automated watchdogs have detected exploits in real time, recovering funds within minutes. Institutions that instrument blockchain activity well can respond before losses become permanent.

Several major losses in 2024-2026 originated from failures surrounding protocols, not contract code. Most institutional risk registers address only one of the four threat layers.

Recently, @jpmorgan cited persistent security flaws as a barrier to institutional DeFi participation. The concern is legitimate, and addressing it requires a different security posture than what most institutions currently have.

Traditional audits review code at a point in time. With continuous security, you can validate the design before code is written, build on secure foundations, catch vulnerabilities continuously, and keep production safe as it evolves. See how it works ↓ openzeppelin.com/news/introduci…

Today we're introducing the OpenZeppelin Continuous Security Program. A subscription-based engagement that brings a decade of OpenZeppelin security standards and expertise to your team continuously, scaled by AI-native workflows powered by AI Auditor.

We're at @SuiNetwork Live today, come by the booth to connect!

Zama is now supported natively by the @OpenZeppelin relayer, making it easy for developer to start building confidential applications. Making confidentiality the new default onchain will require great tools and integrations across the ecosystem. This is our primary goal for 2026. openzeppelin.com/news/openzeppe…

Join us at @SuiNetwork Live to learn how our audited Move contracts libraries can support your app in DeFi, RWAs, gaming or digital commerce 💧 openzeppelin.com/networks/sui

To get started, see the end-to-end Zama FHEVM example with the OpenZeppelin Relayer 👇 openzeppelin.com/news/openzeppe…

The OpenZeppelin Relayer now supports @zama FHEVM 🔐 Build confidential smart contracts without the transaction infrastructure overhead. FHE stays in Zama's SDK. The Relayer covers transaction submission with encrypted inputs and EIP-712 signing.

We've published OpenZeppelin's Technical Risk Assessment on Blockchain Networks: a structured 6-dimension methodology currently covering Ethereum, Solana, BSC, XRP Ledger, Tron, and Canton. Get the full 48-page report ↓ openzeppelin.com/news/technical…

When financial institutions put client assets onchain, supervisors expect a defensible answer to one question: how was the blockchain network evaluated? Networks differ in finality guarantees, governance, and continuity exposure. And those differences shape regulatory risk.
