Axiom Chain Labs is a security-first engineering studio. We audit smart contracts, harden Web3 infrastructure, and build decentralized applications that hold up under real capital — not just testnets.

Info
Every engagement ships with a public-facing report hash anchored on-chain for verifiability.
Trusted by protocol teams, DAOs, and venture-backed Web3 startups
What we do
We work across the full lifecycle — from pre-deployment review of a single contract to operating the infrastructure your protocol depends on at scale.
Manual line-by-line review paired with fuzzing, invariant testing, and formal reasoning on critical paths. We report severity-ranked findings with reproducible proofs of concept — never vague warnings.
Node fleets, indexers, relayers, and RPC layers engineered for uptime. We design resilient architectures with observability, failover, and key management built in from day one.
End-to-end product engineering: protocol contracts, wallet integrations, and interfaces that feel native to Web2 users while staying fully non-custodial under the hood.
How we work
No black boxes. Every engagement runs on a fixed timeline with a named lead auditor, weekly syncs, and a report you can hand directly to your investors.
Start a scoping call01
We map the protocol's trust assumptions, asset flows, and privileged roles, then agree on a scope and a fixed quote before work begins.
02
Two auditors review in parallel. Static analysis and property-based fuzzing run alongside to catch edge cases humans miss.
03
You get a severity-ranked report with proofs of concept and concrete fixes. We stay in the loop through your remediation PRs.
04
Every fix is verified. The final report is published with an on-chain hash so your community can independently confirm it.
Our vision
Axiom Chain Labs was founded by protocol engineers who spent years watching preventable exploits drain user funds. We started this studio on a single premise: decentralized systems only earn trust when the code underneath them is genuinely trustworthy.
That's why every engagement is led by a senior auditor — not delegated to juniors — and why our reports are written for humans first and machines second. We're deliberately small, take a limited number of clients per quarter, and decline work we can't give our full attention to.
Our long-term goal is simple: make the on-chain economy boring to attack.

Remote-first
We assume the attacker has read your docs, your governance forum, and your private mempool. Our reviews start from that position.
Fixed quotes, fixed dates, and a named point of contact. If scope changes, we tell you before it affects the invoice.
Findings are written for engineers and founders alike, with reproduction steps and clear severity rationale — no cryptic jargon.
Tell us about your protocol and timeline. We'll reply within one business day with a scoping questionnaire and an honest assessment of fit.
