OpenZeppelin is now officially a part of S&P Global.
The acquisition we announced in September is finalized. OpenZeppelin’s decade of securing and building the infrastructure onchain finance runs on now meets @SPGlobal's more than a century of helping markets understand risk. Together, we can help institutions and builders move onchain with greater confidence.
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.
• Security audits, secure development work and ecosystem programs continue with the same team, brand, quality and customer experience, now backed by S&P Global’s research capacity, market data and institutional reach.
For the last decade, OpenZeppelin has set the security standard for onchain finance. Now we take it to the scale of global finance.

secure private state management is now available and open source, for institutional confidentiality, coordination, and compliance
To operate onchain, organizations need privacy and shared control, without handing over the keys.
OpenZeppelin and @0xMiden designed Guardian to that end: the first non-custodial Private State Manager.
Now live as Miden opens to its early partners.

Confidential Tokens are ready to be deployed on Stellar mainnet 🔒
Add a confidential layer to any SEP-41 token you’ve already issued. Balances and payment amounts are no longer visible onchain.
Shipped in @OpenZeppelin's Stellar Contracts v0.8.0.
Also in v0.8:
• Ready-made RWA (@trex_network) compliance rules: country restrictions, holding limits, lockups and transfer limits
• A simpler way to build tokens: choose your features in one line, with type-safe composition built in
github.com/OpenZeppelin/stel…
OpenZeppelin Contracts for Stellar v0.8 is live, introducing the Confidential Token 💫
Add a confidential layer on top of any SEP-41 token to keep balances and transfer amounts private, with compliance controls built in.
Full release ↓
Confidential Token is designed for regulated finance: amounts and balances stay private, parties stay visible.
Compliance oversight applies where the rules require it and selective disclosure lets a holder prove a single fact to a third party.
Start testing audited contracts ↓

Private @0xMiden accounts keep only a commitment onchain. So how do @joinBread multisig cosigners stay in sync?
Guardian stores & validates state deltas offchain and cosigns the transaction as an independent check the ZK proof requires. It can’t move funds alone.
See it live ↓
Guardian is open-source and self-hostable, so any team can run its own instance.

Today we’re announcing a strategic partnership with @chainlink
Chainlink CCIP and ACE are now natively embedded across OpenZeppelin tooling, giving institutions and developers one trusted foundation for moving assets and operations onchain.

Onboarding trillions of assets onchain is a shared effort across standards, infrastructure, and security.
OpenZeppelin is proud to be part of the Tokenized Asset Coalition, contributing the foundations institutions need to bring finance onchain with confidence 🔒
Very excited to announce we're welcoming 12 new members.
Another step toward our mission of onboarding the next TRILLION of assets onchain.
With the SEC opening the door to tokenized stock trading onchain:
- We've added a regulated broker-dealer building lending against tokenized NMS stock
- We're deepening our DeFi bench with leading lending protocols and onchain asset managers
- We've brought on the infrastructure tokenization runs on: smart contract security, onchain accounting, blockchain data and self-custody
- We've expanded into Canton, an ecosystem institutions are adopting quickly
- We're strengthening our research and policy work with two of the most respected standards and policy groups in the space
Meet the new TAC members:
tacoalition.org/p/welcome-to…
We also unveiled the Global Access Protocol (GAP) today, a framework for making tokenized securities composable in DeFi. More on this next week.
Thank you to our returning members, alums and partners for continuing to build this with us!

Exploits rarely start and end in the code. Technical flaws, operational gaps, and human behavior compound each other.
Our Security Research Manager Steven Thornton unpacks how they interact, and how to design for it, at @1inch Groundwork in Washington, DC tomorrow at 3:35 PM ET.

@OpenZeppelin provides architecture, build, and continuous security coverage for financial institutions, networks, and protocols.
They joined us in the Cosmos Partner Network to help global financial players accelerate digital asset initiatives.
OpenZeppelin engineer @boyanxyz looks at what it takes for an issuer to launch a confidential stablecoin on @StellarOrg.
It starts with the open-source confidential token implementation in our Stellar library, currently on testnet.
