WHERE WE WORK
Treat custody as a complete security system.
We assess cryptography in context: the software that invokes it, the infrastructure that hosts it, the people who operate it and the procedures that recover it.
Discuss your environmentSigning policy
Validate quorum, limits, allowlists, transaction context and separation of duties.
Wallet and transaction systems
Test wallet APIs, transaction construction, chain handling and state consistency.
Ceremonies and recovery
Assess key ceremonies, backup, break-glass access, incident response and recovery exercises.
ENGAGEMENT MODEL
From system context to verified improvement.
Focused work that leaves engineering teams with decisions, evidence and a practical route forward.
Model
Map keys, authority, software, infrastructure and operational dependencies.
Challenge
Test compromise, collusion, transaction and recovery scenarios.
Assure
Strengthen control design and validate the implemented protections.
ENGINEERING OUTPUT
Evidence your team can use.
Clear artefacts designed for engineers, security leaders and decision-makers.
- Custody and signing threat model
- Key-management and policy review
- Wallet and integration security findings
- Remediation retest and recovery recommendations
Let’s identify the security work that matters first.
