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]

We're excited to partner with @Trex_Network on the next phase of the protocol's growth.

Together, we're advancing the open-source compliance standard $32B+ in tokenized securities already depend on 🦖

Teams building on @StellarOrg can run the OpenZeppelin Relayer Service in their own cloud.

We added step-by-step deployment guides for AWS and GCP, walking through compute, state, secure key management, fee bumping, and RPC failover ↓

New addition to the OpenZeppelin @StellarOrg toolkit: The Relayer Service💫

Build and scale Soroban apps without setting up servers, managing deployments or maintaining uptime.

Supporting:
• Soroban contract execution
• Sponsored transactions
• x402 agentic payments

[WisdomTree Prime® @WisdomTreePrime]

Bringing regulated funds onchain is a security problem most protocols haven't had to solve.

The trust model has to live in the code.

Three @OpenZeppelin audits, every critical resolved before deployment, zero high-severity findings in production.

[OpenZeppelin @OpenZeppelin]

Tokenizing regulated funds is one of the biggest opportunities in finance, and @WisdomTreePrime is showing what it looks like.

$790M tokenized and live onchain, built to institutional standards and secured by OpenZeppelin's Continuous Security Program.

[OpenZeppelin @OpenZeppelin]

Protocols and financial institutions that understand the agentic payments landscape now will be better positioned to engage with it on their own terms.

[OpenZeppelin @OpenZeppelin]

For most of financial history, a payment required a human decision.

AI agents are changing that, initiating and settling transactions autonomously across both blockchain rails and traditional card networks.

Interesting bug find in OpenZeppelin's smart accounts audit. Worth studying

[Confidential Token Association @ConfTokenAssoc]

The Confidential Token Association works toward a confidentiality standard across blockchains. One interface developers build against, native to each chain.

@StellarOrg's Confidential Token, now on testnet, follows the ERC-7984 interface with ecosystem-specific adjustments 👇

[T-REX Network @trex_network]

Regulated assets will only move onchain at scale when institutions can trust the code enforcing ownership and transfer rules.

That is why T-REX Network is partnering with @OpenZeppelin to co-develop a major upgrade to the infrastructure underpinning ERC-3643 tokenized securities.

For these assets, smart contract security goes far beyond protecting balances.

The code determines who can hold the asset, how identity is handled, where it can be distributed and whether each transfer is permitted.

Those controls need to be reliable from the first architectural decision.

OpenZeppelin engineers will work alongside the T-REX team, advising on the core architecture, reviewing new functionality as it is designed and contributing proven components from the OpenZeppelin Contracts library. That library already underpins 9 of the 10 largest stablecoins and has supported more than $35 trillion in onchain transfers.

The partnership adds OpenZeppelin’s engineering and security expertise to infrastructure already built around ERC-3643 compliance and privacy enabled through @zama.

The result is infrastructure institutions can use to issue and distribute regulated assets with enforceable controls, protected financial data and secure technical foundations.

@ApexGlobalGroup has already committed to adopting the T-REX Ledger as its default infrastructure, with a target of $100 billion in tokenized assets by June 2027.

Institutional adoption depends on getting the foundations right.

OpenZeppelin is now helping us build them.

[OpenZeppelin @OpenZeppelin]

Our work with @Trex_network will bring developers:

→ ERC-3643 support in OpenZeppelin Contracts, out of the box
→ Eligibility and transfer controls across issuers, custodians, and institutional workflows
→ Non-EVM blockchain compatibility

A point-in-time security audit secures your system as it is that day. The next release changes it.

Onchain systems evolve constantly, and the risk runs beyond the contract layer.

We designed the Continuous Security Program to keep that coverage across the full lifecycle ↓

👀 Here's a walkthrough of @OpenZeppelin's Confidential Token demo on Stellar Testnet

Starting with three roles to get familiar with: Account Holder, Verifier and Auditor

For this demo you need two wallets (accounts) 🧵👇

[OpenZeppelin @OpenZeppelin]

Whether it's payments, treasury, or settlement, onchain financial activity needs privacy.

Confidential Tokens bring that to @StellarOrg testnet 💫

Our implementation wraps any SEP-41 token to keep balances and amounts private, with a full compliance suite built in.

[Build on Stellar @BuildOnStellar]

🔐 Today we're introducing our latest privacy feature: Confidential Tokens

A contract suite from @OpenZeppelin, with an UltraHonk verifier implemented by @Nethermind, adding private balances and private transfer amounts to any SEP-41 token.

Available on Testnet👇
