Onchain finance already runs on OpenZeppelin
We shaped the open smart contract standards onchain finance has run on for a decade, and we keep them open by design. Shared, audited standards are how the industry moves forward together, and how institutions adopt onchain with confidence.

Security shaped to the world you operate in
A bank, a network, and a regulator do not share a risk model, compliance requirements, or a stakeholder map. We bring security and risk management made for the specifics of each, not a template stretched to fit.

“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."

Take your most critical onchain initiatives to production, securely
These are the programs where the value and the scrutiny run highest. We cover each one end to end, so yours reaches production on ground you can stand behind.
Tokenization & Asset Issuance
Issue and manage tokenized, securities, and real-world assets. We make sure every instrument is secure before it represents real value, and stays that way after.
Stablecoins & Tokenized Deposits
Launch and operate stablecoins and deposit tokens on the standards behind 9 of the top 10 stablecoins, and issue money your holders and regulators can trust.
Collateral, Repo & Treasury
Bring collateral, repo, and treasury operations onchain. We help you automate balance-sheet operations without automating in risk, with controls your risk teams can verify.
Custody & Asset Servicing
Safeguard client assets in custody, key management, and asset servicing. We secure the whole system around the assets, not just the contract.
Onchain Asset Management & Yield
Launch vaults, tokenized funds, and yield products on the standards behind onchain asset management. We secure the strategy logic, accounting, and access controls your investors and regulators rely on.
Payments, Settlement & Cross-Border
Move value across payment rails, settlement, and cross-border corridors. We help you run around the clock without exposure growing with the volume.
Continuous Security Program
Your systems never stop changing.
Your security shouldn't either.
Onchain systems ship, integrate, and upgrade continuously. Continuous Security covers them the same way, across architecture, development, security, and ongoing support, in any direction as they evolve. A decade of OpenZeppelin standards and expertise, scaled by OpenZeppelin AI.
Held to the standards your institution already answers to
OpenZeppelin meets the highest security and compliance standards while actively shaping industry regulations and engaging with global regulators and policymakers.
