Your first onchain transaction should be your most defensible one.
An institution does not arrive onchain with a codebase. It arrives with a mandate, a custody model, and a committee that needs the risk written down. Guardian works the whole distance: the roadmap that gets you there, the audit of what you deploy, and the offchain surface that ends up carrying the position.
- Advisory & roadmap
- Smart contract audits
- Pentests
The contracts are the smallest part of the picture. Most of what an institution puts at risk onchain is still administered by the systems it already had.
A roadmap and the solutions to come onchain.
The hard part is rarely the contract. It is deciding what custody looks like, who can sign, which chain and which bridge, what happens on a bad day, and how any of it is explained to a risk committee. Guardian advises on those decisions while they are still decisions, and builds the control or the document that answers them.
- 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.
- Diligence answers Technical responses for exchanges, custodians, auditors, and institutional partners asking what your controls are before they will transact.
Each stage produces something you can hand to someone else. Nothing is finished with a verbal recommendation.
Three independent passes over the same code.
Two competing teams review the same scope in parallel — one driving expert manual analysis, one driving billions of tokens of 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.
The passes are independent on purpose. Anything only one of them reaches is a gap the others would have shipped.
- 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.
Nothing onchain has to fail for the funds to move.
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.
- WebApp pentest Authentication, authorization, value-moving flows, client-side surface, business logic, and every parameter the application accepts.
- API pentest Key scoping, endpoint authorization, abuse resistance, surface discovery, and the account-recovery paths that bypass all of it.
- 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.
- Browser extension pentest Permissions and manifest, content scripts, internal messaging, key and session storage, signing flows, and the supply chain behind an update.
Every arrow above the boundary ends in the same place. The review scales with what each surface can actually do, not with how large it is.
Bring us the mandate, not just the contract.
