OpenZeppelin

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

[OpenZeppelin @OpenZeppelin]

Tokenized treasuries, private credit, and regulated funds often settle over days, a timeline synchronous onchain vaults weren't designed for.

We've merged an implementation of ERC-7540 with support from @tokenizedvault members @centrifuge and @superformxyz to solve this.

On @StellarOrg, OpenZeppelin Contracts secure $551M in total value locked, enabling 89% of all smart contract transactions 💫

[Tokenized Vault Foundation @tokenizedvault]

$35T value transferred. ~85% of DeFi built on @OpenZeppelin contracts.

ERC-7540, the standard built for assets that settle on their own timeline, joins core DeFi infrastructure.

An OpenZeppelin implementation, built with @centrifuge and @superformxyz, brings it to developers working on real-world assets.

[Centrifuge @centrifuge]

Out of 8,100+ proposed ERCs, @OpenZeppelin has only implemented a tiny handful of token standards:

ERC-20, ERC-721, ERC-1155, ERC-4626, ERC-6909

ERC-7540 is joining that list: the async vault standard is now part of the toolkit most of DeFi runs on.

ERC-7540 extends the ERC-4626 vault standard with async request-then-claim flows, letting deposits and withdrawals wait on real-world steps like a compliance approval or a wire clearing before any shares move.

A fully audited implementation will follow soon.

Confidential finance is taking shape on @zama, with OpenZeppelin under the hood.

Proud that 11 of 12 winning apps build on OpenZeppelin Contracts, with 8 using ERC-7984, the confidential token standard we co-authored with Zama.

[Jan @dcjanio]

Congrats to the winners of @Zama Developer Program Mainnet Season 2. 👏

234 submissions across 3 tracks. 15 winners. Confidential finance, prediction markets, consumer apps, AI agent tooling were built on the Zama Protocol.

Thanks to everyone who participated. Let's take a look at what the community has built 🧵

[Miden @0xMiden]

The first batch of Guardian operators on Miden is here:

OpenZeppelin
LambdaClass
Gateway

Private accounts are powerful. But if they’re going to be usable in real apps, they need recovery, synchronization, coordination, and serious operators behind the infrastructure.

smart contract safety is harder than the demos make it look. frontier models are 80% of the way there. the missing 20% is the part that protects user funds. ChainBench, a collaboration with @circle, focuses on that 20%.

The Open Intents Framework is live in production at scale ⛺️

We're excited to see @lifiprotocol Intents launch, as it's a significant milestone for the OIF and the broader ecosystem building on open intent infrastructure.

[Circle Developer @BuildOnCircle]

Introducing ChainBench, built in collaboration with @OpenZeppelin.

ChainBench is an LLM benchmark for crosschain smart contract generation, testing how model-agent systems write functional and secure contracts across languages, difficulty levels, and development harnesses.

Key finding: frontier models can make strong progress, but security-critical edge cases still matter.

We have secured DeFi for a decade, and that work now matters more than ever.

We are in it alongside the protocols, institutions, and developers building the next era of finance.

[OpenZeppelin @OpenZeppelin]

Recent posts by Manuel Aráoz on AI and DeFi security have been widely circulated, and customers have asked whether they reflect OpenZeppelin's position. They do not.

Manuel co-founded OpenZeppelin and served as the company’s CTO until 2019 when he left the company.

[OpenZeppelin @OpenZeppelin]

The last month has been a hard one for the industry. But most recent incidents trace back to operational security failures, not smart contract bugs. That distinction matters, and hardening both is the work our team and our partners do every day.

@SuiNetwork OpenZeppelin is a proud sponsor of @SuiNetwork's Overflow Hackathon.

If you're building DeFi primitives or payment rails, the Move-over CTF is your warm-up before you ship.

[OpenZeppelin @OpenZeppelin]

Sui developers, put your Move security skills to the test ⛳️

Move-over is an open source, browser-based CTF. Read the vulnerable contract, write your attack logic and return the flag.

Like Ethernaut, but for @SuiNetwork 💧
