Institutions operate onchain securely with Guardian.
Security services and partnership that match the gravity of regulated onchain operations.
- Advisory & roadmap
- Smart contract audits
- Pentests
A roadmap and the solutions to come onchain.
Deciding what custody looks like, who can sign, which chain and which bridge, and how the smart contracts are designed. Guardian advises on those decisions while they are still decisions, and builds the control or the document that answers them.
Start with advisory- Target architecture What goes onchain and what stays off it, which chain and why, custody and signing model, and the upgrade and pause paths you will need on your worst day.
- Counterparty and integration review The bridges, custodians, oracles, and protocols you would depend on, assessed as concentrations of risk rather than as logos on a slide.
- Control design Trust boundaries, privileged roles, approval thresholds, and key custody, specified before they are built rather than audited after.
- Committee-ready evidence Plain-language risk framing, residual exposure, and control ownership, in the form a risk committee, a board, or a regulator will actually read.
- Technical diligence Technical responses for exchanges, custodians, auditors, and institutional partners asking what your controls are before they will transact.
The Digital Asset Security Pilot.
A low commitment way to work with Guardian, structured to be straightforward for a vendor process to accept. Choose the modules that matter to your roadmap and the engagement is scoped around them.
- Architecture assessment
- Standards alignment
- Assurance engineering
- Smart contract audit
- Offchain pentests
Three independent passes over the same code.
Two competing teams review the same scope in parallel, one driving expert manual analysis and one leveraging frontier AI, while an exhaustive invariant suite fuzzes underneath both. Independent passes find different things. Run together, they leave far less unreached than any one of them does alone.
Start a contract audit- Launches Pre-production review for new markets, token systems, and settlement contracts, scoped by what the code can move rather than by line count alone.
- Upgrades and migrations Parameter changes, governance actions, and hot fixes reviewed against the deployed state, not only against the diff.
- Integrations The protocols, bridges, and oracles you depend on, reviewed at the boundary where their assumptions become yours.
- Economic assumptions Liquidation, pricing, and incentive paths tested where being directionally right is still expensive.
- Remediation to closed Findings are tracked through fix and re-review. A report that lists issues without confirming they were closed is half a deliverable.
Offchain pentests for critical surfaces.
The contracts are one surface. The cloud account that can redeploy them, the web app that decides whether a withdrawal proceeds, the API key that outlives the employee who made it, and the SDK your counterparties install are all on the same path to the same assets. Guardian tests each of them the way an attacker reaches them.
- Infrastructure pentest Cloud posture, IAM and trust policies, data at rest, secrets handling, build and deploy, containers and clusters, and the vendor consoles that can change production. Scope this
- WebApp pentest Authentication, authorization, value-moving flows, client-side surface, business logic, and every parameter the application accepts. Scope this
- API pentest Key scoping, endpoint authorization, abuse resistance, surface discovery, and the account-recovery paths that bypass all of it. Scope this
- SDK audit What the library encodes and hands to a wallet, how it treats keys and credentials, and the gap between the repository and the published package. Scope this
- Browser extension pentest Permissions and manifest, content scripts, internal messaging, key and session storage, signing flows, and the supply chain behind an update. Scope this
