A Avalanche smart contract audit is a security review of code deployed to Avalanche, carried out against the Ethereum Virtual Machine execution model and written in Solidity — covering both the bug classes shared across EVM Layer 1 systems and the failure modes specific to Avalanche.
Avalanche combines a standard EVM C-Chain with a subnet architecture that lets teams run their own chain with their own validator set and rules — which moves a large part of the security question from the contract to the configuration.
On the C-Chain, an Avalanche audit is an EVM audit with fast finality and different gas economics. On a subnet or L1, the security question changes: who validates, what the validator set costs to corrupt, how the gas token is configured, and what precompiles the chain enables.
We cover both: full contract review plus, where relevant, subnet configuration — validator set, permissioning, custom precompiles, fee configuration and cross-subnet messaging.
Avalanche runs on Ethereum Virtual Machine, so it inherits the bug classes below from every system in that family.
Avalanche contracts are written in Solidity. See our Solidity audit methodology.
We fix a commit hash, agree the in-scope contracts and read your architecture docs, then build a threat model: who the actors are, what the trust boundaries are, and which invariants must never break. Nothing is reviewed against assumptions we have not written down.
Line-by-line review by at least two auditors working independently, focused on authorisation, accounting, upgrade paths, external integrations and the gap between what the code does and what the documentation claims it does. Most critical findings come from this phase, not from tooling.
Static analysers appropriate to the language, plus property-based fuzzing and invariant testing to push the system into states no unit test covers. Tooling is used to widen coverage, never to replace the manual pass.
Candidate findings are proven on a forked network with a working proof of concept. We report what an attacker can actually do and what it costs them, not a theoretical severity label.
Every finding gets a severity rating, reproduction steps, the affected code, the impact in concrete terms and a specific remediation. You get a draft for discussion before anything is finalised.
We re-test every remediation against the original proof of concept and check that the fix has not opened a new path. The final report is yours to publish.
Yes — validator set and permissioning, custom precompiles, gas token and fee configuration, and cross-subnet messaging, in addition to the contracts deployed on the subnet.
Largely, with differences in finality, gas economics and any Avalanche-specific precompiles you use. The core contract review is the same discipline.
We review it as a cross-chain trust boundary: who can produce a valid message, replay protection, and what your contract does with a message it should reject.
A repository or contract address, a commit hash to freeze the scope, whatever architecture or spec documentation exists, and a point of contact who can answer design questions. If documentation is thin we will write our understanding of the system back to you and ask you to confirm it — that step alone catches design-level bugs.
A single token contract is 24–48 hours. A typical dApp or mid-sized protocol runs one to two weeks. Large DeFi systems, L2s, bridges and ZK circuits are scoped per project after we have seen the code. We will give you a fixed timeline with the quote, not an estimate that moves.
Yes. Fix review is part of the engagement, not an upsell. We re-run the original proof of concept against your patched code and confirm the fix has not introduced a new path.
