Web3 & Crypto · Blockchain infrastructureHarden the layer under your contracts.
A perfectly audited contract controlled by a leaked key, a compromised RPC or a mis-configured validator is still a loss. We review the infrastructure your protocol actually runs on — nodes, signers, custody and the humans around them.
What we test
- Node and validator hardening: OS, network exposure, peer and RPC configuration
- RPC and indexer security: authentication, rate limits, data integrity
- Signer and key-management architecture: multisig, MPC, HSMs, hot/warm/cold tiers
- Deployment and upgrade pipelines — who can push what, and how it is verified
- Secrets handling in CI/CD, cloud and developer workstations
- Monitoring and incident-response readiness for on-chain events
- Bridge relayers, oracles and off-chain components that feed on-chain logic
What you get
- Architecture review with a prioritised risk register
- Configuration findings with exact remediation steps
- Key-management and custody recommendations fit for your team size
- Incident-response runbook outline for the top scenarios
- Verification review once changes are applied
Who it is for
Protocol teams running their own nodes or signers, validators and staking operators, exchanges and custodians, and any team whose admin keys or relayers can move significant value.
Why it matters
The largest Web3 incidents of recent years were not contract bugs — they were compromised keys, poisoned front-ends and social engineering of operators. Infrastructure is where the money actually leaves.
How an engagement runs
Scope
We agree targets, rules of engagement and what success looks like — in writing, before anything starts.
Recon
We map your full attack surface the way an adversary would, not just the assets you remembered to mention.
Exploit
We attempt real exploitation and chain small weaknesses into business-level impact.
Report
You get prioritised findings, proof-of-concept and remediation steps a developer can act on today.
Retest
We verify every fix so issues stay closed — and you get a clean report to show customers.
Questions about blockchain infrastructure
Do you need access to production systems?
Usually read-only access to configuration and architecture documentation is enough. Where hands-on testing is needed, we agree rules of engagement first and work on staging or with safeguards.
Can you design our custody setup from scratch?
Yes. We design multisig, MPC and HSM-backed setups for treasuries, protocol admin keys and exchange wallets, sized to your team and threat model.
