Vishal Singh

Blockchain Cryptography Security Researcher

Security audits for zkVMs, Layer 2 infrastructure, smart contracts, and cryptographic systems.

I help protocol teams find high-complexity vulnerabilities before mainnet, especially in proof verification, transcript construction, slashing and accounting logic, randomness, verifier internals, and architecture-level trust assumptions.

I work across Solidity, Rust, Cairo, ZK circuits, and FHE for teams building systems where correctness matters under adversarial conditions.

Public + private reviews Security work across zkVM, Layer 2, infrastructure, DeFi, and cryptographic systems.
Critical and high-severity findings Including proof verification, slash logic, transcript construction, and randomness issues.
Strong public track record Contest placements including 3rd, 4th, 6th, 8th, and 9th, plus public technical writeups.
zkVMs, proving systems, and verifier components Verifier logic, transcript construction, Fiat–Shamir, soundness assumptions, and proving-system boundaries.
Layer 2 infrastructure, bridges, and validator systems Slashing, accounting, bridge and messaging assumptions, and operational trust boundaries.
Smart contracts and cryptographic protocol logic High-value protocol reviews across Solidity, Rust, and security-critical cryptographic modules.

If you're preparing for launch, reviewing a design, or need a focused audit of a high-complexity system, the fastest path is to request an audit or book a call.
