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. And we do not only audit: our pre-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.
The security standard onchain finance already runs on
We wrote the libraries and standards onchain finance is built on, and we have spent a decade securing them: $250 billion+ in total value secured across 900+ audits since 2016, with zero exploits in fully-remediated audited code. Every engagement is led by world-class security researchers and scaled by OpenZeppelin AI, with risk assessment and monitoring running throughout, so exposure is caught early, when fixes are cheap.
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.
