Cryptography Audit
Verify that the mathematical foundations of your protocol hold.
Get a quoteA specialist review of the cryptographic primitives, key management schemes, signature mechanisms, and encryption implementations underlying your protocol — including assessment of post-quantum exposure.
Cryptographic vulnerabilities are among the most severe in blockchain security: a flawed signature scheme can allow forgery of any transaction, a weak key derivation function can expose all user funds, and a misimplemented zero-knowledge proof can invalidate every privacy guarantee in your system. Deep Guard's cryptography audit goes beyond standard smart contract review to examine the mathematical and implementation-level security of the cryptographic foundations your protocol depends on.
Our process, step by step.
Every engagement follows a structured methodology. No steps are skipped. No shortcuts are taken.
Primitive Inventory
We catalogue every cryptographic primitive in use across your stack: signature schemes, hash functions, key derivation functions, commitment schemes, zero-knowledge proof systems, and any custom cryptographic constructions.
Implementation Review
Each primitive is reviewed at the implementation level for correct usage, known weaknesses in the specific library version deployed, side-channel exposure, and deviation from the specification.
Key Management Analysis
Review of how keys are generated, stored, rotated, and destroyed across your system — covering both on-chain key management mechanisms and the operational security practices of your team.
Protocol-Specific Cryptography
For protocols using custom cryptographic constructions — novel ZK circuits, threshold signature schemes, commit-reveal mechanisms — Deep Guard performs a targeted security analysis of the construction's assumptions and edge cases.
Post-Quantum Assessment
Evaluation of your protocol's exposure to quantum-era attacks: which cryptographic assumptions are vulnerable to Shor's or Grover's algorithms, the timeline of practical risk, and a migration roadmap toward post-quantum primitives.
Cryptographic vulnerability report
Documented findings covering implementation errors, misused primitives, weak parameters, and key management failures.
Post-quantum readiness assessment
A clear view of your protocol's exposure to quantum-era attacks and a prioritised migration roadmap.
Key management recommendations
Concrete improvements to key generation, custody, rotation, and destruction practices — on-chain and operational.
Cryptographic architecture guidance
Recommendations for primitive selection, library choices, and construction patterns that improve long-term cryptographic security.
