Take your digital asset programs to production, securely
The security partner that takes payments, settlement, collateral, custody, and tokenization from pilot to production, with the assurance your security, compliance, and risk functions require.
Trusted by leading financial institutions and blockchain protocols
Going onchain is no longer the hard part. Making it defensible is.

Banks are already issuing tokenized deposits, settling onchain, and mobilizing tokenized collateral in production. As that work moves from innovation teams into core operations, the decisive question is no longer technical feasibility. It is whether a program can meet the security, compliance, and risk standards an institution is held to, across its entire lifecycle.
That assurance has to be established at every step of the way.
Architecture, governance, upgrade paths, and key-management design determine whether a system is defensible, and they are set before any code is written, where they are hardest to revisit.
Developing onchain from scratch is slow and error-prone. Reaching production on unproven patterns puts both time-to-market and security at risk, and institutions can compromise on neither, least of all security.
Exposure spans code, infrastructure, and operations: keys, oracles, bridges, and signing. A point-in-time review of the contract alone leaves most of the surface uncovered.
Onchain systems, and the chains and protocols they depend on, change continuously. Assurance at launch says little about exposure six months later.
Security coverage mapped to your onchain business
Wherever your bank moves money and assets onchain, here is the specific risk it carries and how OpenZeppelin removes it.
- Payments & Settlement
Move money borderless around the clock, with finality you can trust
- We harden the deposit-token and stablecoin logic, the settlement atomicity, and the cross-chain interfaces your payments run on, so 24/7 availability never means 24/7 exposure. Coverage spans transfer and minting controls, delivery-versus-payment logic, and the operational security around signing and reconciliation.
- Treasury & Liquidity
Automate treasury without automating risk onto your balance sheet
- Programmable liquidity rules only help if they execute exactly as designed. We review the conditional-payment, sweep, and access-control logic behind your treasury flows, then translate the findings into risk assessments your treasury and risk functions can sign off on.
- Collateral & Repo
Mobilize collateral intraday, with the assurance your risk committee needs
- Intraday movement removes the human checkpoints that used to catch errors. We model the failure modes and validate finality, liquidation, and collateral-parameter governance, so speed never introduces settlement or operational risk.
- Custody & Asset Servicing
Safeguard client assets to the standard your charter and clients demand
- Custody risk lives in the whole system, not just the contract. We assess key management, signing infrastructure, access controls, and upgrade governance together, the way an attacker would, advise on custody technology trade-offs, and build the standards and reference implementations for secure asset servicing.
- Tokenization & Issuance
Issue tokenized funds, deposits, and stablecoins on proven foundations
- We secure the issuance, compliance, and lifecycle logic of every instrument you bring onchain, on the same standards behind 9 of the top 10 stablecoins and 10 of the top 10 tokenized funds. Our security-audited reference implementations and tokenization solutions let your team reach production faster on foundations that are already secure.
Across all of the above
Counterparty & Onchain Due Diligence- Before your bank relies on a counterparty, chain, protocol, or asset behind any of these, our Technical Risk Assessment gives your vendor-risk and compliance teams regulator-ready analysis to make the call, built to withstand scrutiny across MiCA, DORA, and Basel, and to support license applications and internal risk reviews. Once you are live, custom monitoring keeps that risk picture current.
“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.”
“Huge thanks to OpenZeppelin for being a great partner during the security audit — their expertise and constant support were invaluable for the entire engagement.”
From architecture to production, one security partner
Taking a digital asset program to production is not a one-time security audit. Architecture, build, launch, and operations each carry their own risk, and that risk keeps shifting as the system reaches new chains, assets, and counterparties. OpenZeppelin works across all four stages as a single partner, led by world-class researchers and scaled by OpenZeppelin AI, and calibrated to your program's scale, complexity, and regulatory context.

Coverage shaped around your program, not a fixed package
We combine services from across the lifecycle into the mix your program actually needs, and adjust it as the system moves from a first deployment into full production across multiple chains and assets. Engage on a defined-scope project, or through the Continuous Security Program for ongoing coverage.
The security standard onchain finance already runs on
The banks taking digital asset programs to production rely on proven foundations. 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, the same open standards your tokenized deposits, settlement, and custody programs can run on.
For institutional programs, a Dedicated Blockchain Architect can be embedded as your single point of contact for security across the full lifecycle, from architecture through production, backed by OpenZeppelin's full research organization. Engage on a defined-scope project, or through the Continuous Security Program for ongoing, subscription-based coverage bundled around your needs.
