Custody architecture
Review hot, warm and cold wallet boundaries, quorum design and transaction approval paths.
Industry / Digital assets
Secure digital-asset operations end to end.
Security engineering for exchanges, custodians, wallet platforms, token infrastructure and the operational systems around them.

PROTECTION OBJECTIVE
Protect keys, signing authority, wallet state and the human workflows that control digital value.
Custody architecture Key lifecycle Wallet operations Recovery readiness
WHERE WE WORK
Protect the full operating system around digital assets.
A strong cryptographic primitive is not enough. We assess how policies, software, infrastructure, operators and recovery procedures combine around custody and transactions.
Discuss your environmentKey lifecycle
Assess generation, storage, use, rotation, backup, revocation and recovery controls.
Wallet and chain interfaces
Test wallet services, signing APIs, smart-contract integrations and state-handling logic.
Operational security
Validate privileged workflows, ceremonies, monitoring and incident recovery procedures.
ENGAGEMENT MODEL
From system context to verified improvement.
Focused work that leaves engineering teams with decisions, evidence and a practical route forward.
Map
Trace control of assets across keys, systems, people and external networks.
Strengthen
Improve signing, access and operational controls around credible loss scenarios.
Exercise
Validate transaction, recovery and incident workflows before they are needed.
