Ship onchain products at fintech speed, on foundations millions of customers can trust

Stablecoin accounts, tokenized investing, and onchain payments are becoming standard features in digital finance. OpenZeppelin develops the components, standards, and tooling your team may not have in-house, and secures every release, so your roadmap and your customers' trust grow together.

For digital-first financial services, going onchain arrives as features: a stablecoin balance, a tokenized stock, instant cross-border transfers, yield on idle cash. Each one ships on your product cadence, reaches retail customers at scale, and depends on contracts, wallets, networks, and third-party providers that sit largely outside your core systems. Your licenses, your banking partners, and your customers hold you accountable for all of it, and a single incident reaches every customer at once.

Get the foundations right, and every new onchain feature compounds customer trust.

Wallet model and key custody, the networks and stablecoins you support, how customer balances map to onchain positions, and upgrade and admin controls are decided when the first onchain feature ships. They are hard to change once millions of accounts depend on them.

Token issuance, smart-account wallets, and cross-chain integration take specialist onchain engineering that most product teams have yet to hire. Hiring takes quarters, and handing the core of a feature to a proprietary provider hands its roadmap over too.

Most onchain stacks in digital finance are assembled from wallet infrastructure, custody, on- and off-ramps, stablecoin issuers, and the protocols behind yield products. Their failures become your incident, and a review of your own code covers only part of that surface.

Each new feature, market, and network multiplies exposure, and every onchain change is permanent the moment it deploys. The assurance you had at launch says little about your exposure several product cycles later.

Where OpenZeppelin helps, across every onchain feature in your app

From customer wallets to the assets you issue and the networks you run on, here is what OpenZeppelin develops with you and how we secure it.

Stablecoin Accounts & Wallets

Give customers onchain balances with custody controls that hold at scale

We develop smart-account and embedded-wallet components on OpenZeppelin Contracts, including recovery, signing policies, and session keys, tailored to your app's experience. Then we review the key controls that keep one compromised device or operator away from customer funds.
Token Issuance & Custom Standards

Issue your own stablecoin, token, or product on proven foundations

When your product needs a token, or a standard the market has yet to provide, we develop it with you: issuance and redemption, reserve controls, pause and freeze, and custom extensions on the same foundations behind 9 of the top 10 stablecoins by market cap. Every release is reviewed before it reaches customers.
Tokenized Investing

Offer tokenized stocks, funds, and bonds with the integrity of the underlying asset

We develop the integration layer between your app and the issuers and venues behind the instruments you offer, and review issuance, redemption, corporate-action, and transfer logic, so every token reflects the asset behind it.
Payments, Cards & Transfers

Move customer money instantly, across borders and between apps

Onchain transfers settle in minutes and are irreversible, so screening has to hold wherever your ledger meets the blockchain. We develop and review transfer, card-settlement, and on- and off-ramp flows together with the compliance controls around them, so speed comes with control.
Your Own Network

Launch your own chain with the standards and tooling developers expect

A growing number of digital-first firms are launching their own networks to control fees, settlement, and user experience. We bring OpenZeppelin Contracts and developer tooling to your network, and review the chain or rollup infrastructure, bridges, sequencer, and upgrade controls before launch.

Across all of the above

Provider, Protocol & Onchain Due Diligence
Before you integrate a wallet provider, custodian, stablecoin, network, or the protocols behind an earn product, our Technical Risk Assessment gives your risk and compliance teams analysis designed to withstand regulatory and supervisory scrutiny, and to support license applications and banking-partner reviews. Custom monitoring alerts you when a dependency changes.
WisdomTree
“Bringing regulated funds onchain means security and compliance have to be inseparable, and they have to hold across every environment we build on. OpenZeppelin has been a continuous partner from architecture through deployment, across both our Ethereum and Solana work, and this consistency and rigor allows us to advance WisdomTree’s tokenization roadmap confidently, at scale.”
— Jason Guthrie, Head of Product, WisdomTree Digital Assets
DTCC
“Huge thanks to OpenZeppelin for being a great partner during the security audit — their expertise and constant support were invaluable for the entire engagement.”

The foundations behind the assets your customers already hold

The stablecoins and tokenized funds your customers hold are very likely running on OpenZeppelin already. The libraries behind 9 of the top 10 stablecoins and 10 of the top 10 tokenized money market funds by market cap are OpenZeppelin Contracts, so shipping your features on the same standards puts your stack alongside the assets your customers already trust.

Every engagement pairs OpenZeppelin researchers and engineers with OpenZeppelin AI, with risk assessment and monitoring running throughout, so issues surface early, while they are still cheap to fix.
