Web3 penetration testing

Web3 penetration testing is a proactive security assessment that simulates real-world cyberattacks to identify vulnerabilities across applications, networks, and infrastructure before malicious actors can exploit them. It combines blockchain expertise with traditional offensive security techniques to protect smart contracts, custody systems, wallets, and backend services.

Web3 environments introduce unique risks such as smart contract interactions, key management, on-chain/off-chain communication, and custody infrastructure. Effective Web3 penetration testing requires deep knowledge of blockchain architecture, decentralized systems, and compliance frameworks in addition to traditional web and network security testing.

CertiK tests applications (web, mobile, desktop, browser extensions, APIs), internal and external networks, blockchain RPC infrastructure, cloud environments (AWS, Azure, GCP), AI-integrated dApps, SDKs, and source code to uncover business logic, cryptographic, and dependency risks across the full Web3 stack.

Penetration testing helps identify exploitable weaknesses before attackers do, reducing the risk of financial loss, data breaches, and reputational damage. It also demonstrates a clear commitment to security, strengthening user confidence and ecosystem trust.

CertiK delivers a comprehensive report that includes an executive summary, threat modeling, detailed technical findings, severity classifications, reproduction steps, proof-of-concept evidence, and actionable remediation recommendations tailored to the project’s risk profile.

CertiK’s pentesters employ the same tactics, techniques, and procedures as threat actors. This includes reconnaissance, vulnerability analysis, exploitation attempts, privilege escalation, and lateral movement to evaluate how an attacker could gain and maintain unauthorized access.

The process includes five phases: preparing and defining scope, exploring assets through reconnaissance, exploiting identified vulnerabilities, escalating privileges to simulate deeper compromise, and delivering detailed findings with remediation guidance to strengthen defenses.

CertiK aligns testing methodologies with industry-recognized standards such as OWASP, NIST, PTES, and CREST, and supports regulatory frameworks including SOC 2, ISO 27001, MiCA, DORA, HKSFC, and MAS, helping projects meet both technical and compliance-driven security requirements.

Completed penetration tests are reflected on a project’s profile, contributing to improved Skynet Score metrics in Code and Operational categories. Public pentest records provide transparent proof of security efforts to the broader Web3 community.

CertiK’s in-house team consists of certified security professionals with both offensive and defensive expertise, backed by continuous research in Web2 and Web3 security. This research-driven approach enables the team to stay ahead of emerging threats and deliver high-impact, real-world testing results.
