API Security Testing
— Crypto & Blockchain
Proof-driven API Security Testing for organizations in Crypto & Blockchain. We deliver validated exploit evidence, not automated scanner noise.
Free Scoping CallCrypto & Blockchain Vulnerability Intelligence
Crypto exchanges and DeFi protocols control billions of dollars in digital assets. Smart contract vulnerabilities are irreversible once exploited, making pre-deployment security audits existentially critical.
Reentrancy Attacks in Smart Contracts
Recursive calling vulnerabilities in Solidity smart contracts allowing attackers to drain funds by repeatedly calling withdrawal functions before balance updates complete.
Flash Loan Oracle Manipulation
Price oracle manipulation attacks using flash loans to artificially inflate or deflate asset prices, enabling profitable liquidations and arbitrage exploitation.
Private Key Management Vulnerabilities
Insecure storage and handling of hot wallet private keys, weak entropy in key generation, and insufficient multi-signature enforcement in custody solutions.
Bridge Protocol Exploits
Cross-chain bridge vulnerabilities in validator sets, signature verification, and message relay mechanisms that have accounted for $2B+ in losses.

Frequently Asked Questions
How long does the API Security Testing process take?
Typically 1-4 weeks depending on scope and infrastructure complexity. We provide a firm timeline after discovery.
What do the deliverables look like?
Each finding includes exploit proof (PoC), business impact score, and developer-friendly remediation code — plus an executive summary.
Is the report valid for regulatory audits?
Yes. Our reports are accepted as audit evidence for ISO 27001, PCI-DSS, SOC2, GDPR, and HIPAA compliance processes.
