What it is
Blockchain security infrastructure encompasses the systems and controls that protect private keys, transaction signing, node operations, and on-chain assets from theft, manipulation, and unauthorised access across an organisation's entire blockchain footprint.
What you get
Smart contract audits secure the code. Blockchain security infrastructure secures everything else: the private keys that control wallets and admin functions, the signing processes for transactions, the nodes that connect to the network, the monitoring that detects anomalous activity, and the incident response process when something goes wrong.
We design and implement multi-signature wallet structures that require multiple approvals for sensitive operations, hardware security module (HSM) integration for key storage, time-lock controls on administrative functions, and on-chain monitoring with alerting for unusual transaction patterns.
For enterprises with existing blockchain deployments, we conduct security assessments across the full stack — contract permissions, key management practices, node configuration, and operational security — and produce a prioritised remediation plan.
Key capabilities
Each engagement is scoped to your requirements — these are the core capabilities we bring to the table.
On-chain transaction monitoring and anomaly alerting
Blockchain node hardening and access control
Incident response planning and key rotation procedures
Security assessment of existing blockchain infrastructure
Penetration testing for Web3 applications
Our process
A structured, engineering-led approach that moves from understanding your goals to a production system — with no handoff surprises.
Typical engagement
8–16 WEEKS
We map your goals, constraints, and existing infrastructure. Scope is defined and success criteria agreed before any development begins.
We design the technical approach, select the right tools, and produce a milestone-driven delivery plan with no ambiguity.
Iterative development with regular demos. Code reviews, test coverage, and documentation happen in parallel — not at the end.
Production release with monitoring setup and handover documentation. We stay close during the first weeks post-launch.
Private key compromise. Unlike a database breach, stolen private keys mean immediate, irreversible loss of assets. The solution is never storing private keys on internet-connected systems, using multi-signature wallets that require multiple approvals, and implementing hardware security modules for signing. We design these controls as the foundation of every engagement.
We implement monitoring via Forta Network agents, custom event listeners, and on-chain data indexers (The Graph) that alert on defined conditions: large transfers, admin function calls, unusual token flows, or contract interactions that deviate from expected patterns. Alerts are routed to your incident response team in real time.
Yes. We provide emergency incident response to contain and assess blockchain security incidents, including transaction tracing, attacker address analysis, identification of the exploit vector, and coordination with exchanges to freeze attacker funds. We also help implement fixes and conduct post-incident reviews.
