Guardian is the standard for onchain security.
From audit to continued security operations, Guardian has specialized in onchain security at the forefront of the industry since day one.
- Smart contract audits
- Pentests
- Managed Security
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- Two Teams Team A drives expert manual review, Team B directs billions of tokens through every corner of the codebase, and each team cross-checks the other.
- Helix AI Auditor An exhaustive search across the whole codebase, hundreds of parallel agents over several days, with only human-verified findings reaching the report.
- Invariant Fuzzing Your core safety properties written as executable invariants and pressure-tested against every reachable state, left runnable after the engagement.
A security audit designed to protect onchain teams facing unprecedented cyber risk.
Two competing teams
Two independent teams attack the same protocol in parallel using distinct methodologies for maximum coverage.
Frontier AI coverage
Billions of tokens of frontier-model attack search across the codebase.
Exhaustive fuzzing
Deep invariant and property fuzzing over the full state space.
$100,000 contest
A funded public contest staked on the quality of the audit.
$50,000 bounty match
A hosted bug bounty with matching up to $50,000.
Web2 Coverage
Cover yourself against the most common exploit vectors in 2026 with half the package cost back as web2 credits.
Post-launch updates auditing
Update review included, so post-audit changes stay covered.
Offchain pentests for critical surfaces.
The contracts are one surface. The cloud account that can redeploy them, the frontend that decides what a user signs, the keeper that fires a transaction, and the SDK your integrators install are all on the same path to the same assets.
Each engagement scales with what the surface can actually do, not with how large it is.
- Infrastructure pentest Cloud posture and IAM, secrets handling, build and deploy integrity, containers and clusters, and the vendor consoles that can change production. Scope this
- WebApp pentest What the frontend trusts from the API, what a user is actually shown before signing, supply-chain exposure in the bundle, and the flows that move value. Scope this
- API pentest Key scoping, per-object authorization, abuse resistance, and the endpoints that fire relayers, bots, or onchain transactions. Scope this
- SDK audit Transaction construction, key and credential handling, response trust, and the gap between the repository and the published package. Scope this
- Offchain automation pentest Keepers, sequencers, risk engines and oracle update scripts: what fires each run, and what a mistimed, skipped, or duplicated run does onchain. Scope this
Your operational risks, managed through time.
An audit is a point in time over a subset of your system. Managed Security is the rest of it, held continuously: who can sign, what is actually deployed, what faces the internet, and what changed this week that nobody reviewed.
- Operational security and controls Access and permissions across every system, secrets handling, release and change control, environment separation, and incident runbooks rehearsed before they are needed.
- Shield Continuous coverage of internet-facing surfaces and networks: hosts, ports, storage, TLS and certificates, edge rules, DNS and registrar control, each finding verified by an engineer.
- Multisig management Signer set and threshold reviewed as people join and leave, signer device hygiene, transaction simulation before approval, and recovery that has been tested rather than assumed.
- Contract inventory Every address you have deployed, on every chain, with its owner, its upgrade path, and whether the code running today is the code that was reviewed.
- Real-time operational risk tracking Changes to the estate surfaced as they happen: a new deployment, a rotated signer, a permission granted, an unreviewed upgrade going live.
Bring us your highest-value system.
Whether that is the next launch, the upgrade going out on Thursday, or the estate you have not had a clear picture of in a year.
