See you at @blockworksDAS NYC next week 🗽 As a Platinum Sponsor, we'll be there meeting with financial institutions, fintechs, and infrastructure providers shaping tokenization and digital asset use cases. Meet our team at DAS 👇

We built the open-source x402 Facilitator Plugin that power pay-per-request stablecoin payments on Stellar, settled via the relayer infrastructure. No billing systems. No API keys. One HTTP round-trip. github.com/OpenZeppelin/r…

Just wrapped a great panel at @mmerge_io São Paulo with @rodventures @solangegueiros and @thiagorudiger on the infrastructure institutions actually need to go onchain. TLDR: → Institutions are in production, not pilots. DTCC, Fidelity, WisdomTree all live leveraging @OpenZeppelin products and services. → Security is shifting from one-off audits to continuous assurance, more news on that April 1st. → The real blocker for RWA scale isn't tech, it's that every platform treats compliance as a moat instead of a shared utility. → Brazil keeps punching above its weight 🇧🇷

Snapshot now natively supports @OpenZeppelin Governor ✨ and Governor Bravo. With gasless voting, delegates dashboard, execution builder, transaction simulation, custom domain and much more. Live today with @ensdomains and @Uniswap. blog.snapshot.box/snapshot-is-no…

The industry-standard smart contract library just landed on Sui. @OpenZeppelin is bringing battle-tested DeFi math primitives and access control to Move. Start building with it today!

Start building building with OpenZeppelin Move Contracts for Sui ⚒️ Docs: docs.openzeppelin.com/contracts-sui GitHub ↓ github.com/OpenZeppelin/c…

The Cetus exploit showed how one math library flaw can cascade across an ecosystem. Our first release addresses the most critical needs: • DeFi Math Library with 12 battle-tested functions • Access Control module for permissions Fully audited and production-ready 🔒

OpenZeppelin Move Contracts are now live on @SuiNetwork 💧 The same library securing over $35 trillion in onchain value and trusted by the industry's most critical protocols is now purpose-built for Sui. Here's what's in the first release 👇

Defense in depth means securing the people, processes, and infrastructure around your code 🔒 We wrote about what that looks like in practice ↓ openzeppelin.com/news/introduci…

As smart contract security matures, attackers are moving up the stack. Code audits are essential, but they don't address compromised signers or malicious dependencies.

Today, most blockchain hacks aren’t smart contract bugs. They stem from phishing attacks, stolen keys, compromised accounts, blind signatures, and operational vulnerabilities. Take the $1.4 billion ByBit hack: the exploit didn't target the code; it targeted operational security.

x402 allows AI agents to make autonomous micropayments without API keys, subscriptions, or human intervention. We are excited to power x402 payments on @StellarOrg with OpenZeppelin Relayer framework and audited smart account contracts 🔒

Introducing OpenZeppelin Skills 🤖 In the first of a series of releases, we're dropping 9 skills to give AI agents authoritative, up-to-date knowledge of OpenZeppelin Contracts libraries for secure smart contract development, setup, and safe upgrades. github.com/OpenZeppelin/o…

Cubewire's Vault smart contracts for Conduit Digital Holdings have earned strong results from an independent security audit by @OpenZeppelin - who authored the very foundations our contracts are built on. Read the full report here: openzeppelin.com/news/cubewire-…
