Smart contract auditing, web application penetration testing, and vulnerability research — conducted under formal engagement and responsible disclosure.
Authorized defensive security testing and research
Static analysis with Slither, Foundry, and Aderyn. Manual review of Solidity codebases for reentrancy, access control, oracle manipulation, and economic invariant vulnerabilities on Ethereum, BSC, Arbitrum, Base, and other EVM chains.
OWASP-aligned testing: injection (SQL, XSS, SSTI), authentication bypass, authorization flaws (IDOR/BOLA), API security, cloud misconfiguration, and exposure assessment on authorized targets.
Automated and manual discovery of security weaknesses across attack surfaces. CVE correlation, version fingerprinting, and misconfiguration detection with proof-of-concept validation.
Controlled attack simulations on authorized lab environments (OWASP Juice Shop, VAmPI, CRAPI) and client infrastructure under explicit written authorization. Multi-stage attack chain modeling.
Development of internal security testing frameworks. Integration of static/dynamic analysis pipelines. Automated vulnerability triage and reporting workflows.
Coordinated vulnerability disclosure through established bug bounty platforms (Immunefi, Sherlock) and direct engagement with protocol teams. Findings reported with proof-of-concept and remediation guidance.
Industry-standard frameworks and tooling
Independent security research, professionally conducted
HardSecure is an independent security research practice specializing in blockchain smart contract auditing and web application penetration testing. We work with DeFi protocols, Web3 startups, and enterprise clients under formal engagement agreements.
All testing is performed exclusively on systems we own, operate, or have explicit written authorization to test — including controlled lab environments, bug bounty programs (Immunefi, Sherlock), and direct client engagements.
We maintain a security program aligned with CIS Controls v8, enforce least-privilege access, and follow responsible disclosure practices for all findings.
