Blockchain infrastructure audit
Harden every layer of your blockchain infrastructure against critical exploits. We review node and client software, cross-chain systems, validator operations, and the off-chain services and deployment pipelines that keep a network running.
What a blockchain infrastructure audit covers
Smart contracts are only one layer. A protocol can have flawless contract logic and still halt, fork, or mint from a bad message because of a bug in the node, the bridge, or the release pipeline. Infrastructure audits review the software around the chain: the code that accepts network messages, keeps state, validates blocks, and moves assets between chains.
We assess consensus and networking code you wrote or modified, RPC and P2P surfaces that parse untrusted input into state, bridge and light-client verification, validator and sequencer key handling, and the genesis, upgrade, and migration tooling that can install a change across the network.
Layers we assess
- Nodes and clients: consensus assumptions, syncing, fork handling, RPC behavior, mempool behavior, and P2P surfaces where a malformed message can halt or split the network.
- Cross-chain systems: bridges, relayers, replay protection, finality assumptions, validator sets, and message verification on both sides.
- Off-chain infrastructure: indexers, keepers, APIs, backend services, signing flows, deployment pipelines, and monitoring.
- Validator and sequencer operations: key custody, rotation, slashing exposure, and who may change a live parameter.
- Launch readiness: test strategy, fuzzing setup, CI detectors, incident response, and operational runbooks.
- Model-driven automation: any AI system that scores, proposes, or applies a configuration the chain then accepts.
Enterprise infrastructure readiness
Institutions building on distributed ledger technology need more than a code review. We assess architecture, on-chain and off-chain components together, and map the results to the controls your regulators and partners expect, including ISO/IEC 27001, SOC 2, CCSS, and DORA.
We prepare the evidence and remediation plan; an accredited body issues the certificate. The compliance pages describe how the two fit together.
What you get
- A written findings report with severity, difficulty, and exploit scenario for every issue.
- Runnable proofs of concept for high-severity findings, so your engineers can reproduce and verify fixes.
- Architecture and operational recommendations: not just bug fixes, but the process changes that prevent the next class of bug.
- Fix verification when your patches land, and a final report you can share with partners, exchanges, and auditors.
Questions
- Do you audit forks of existing clients?
- Yes. Most infrastructure work is a modified client, a custom consensus module, or a bridge built on an existing framework. We focus the review on your changes and the assumptions they inherit from upstream.
- Can you audit the bridge and the contracts together?
- Yes, and we recommend it. Bridge failures live between the contract that accepts a message and the relayer or light client that produced it. One engagement covers both sides so nothing falls between scopes.

Tell us which node software, bridge, or infrastructure components are in scope, the languages they are written in, and what a failure would mean for funds or finality. We will propose an audit plan and estimate.
