SECURITY FIRST
Why Proactive Wallet Penetration Testing is Essential
Reactive security is a liability. Our proactive penetration testing identifies and remediates critical vulnerabilities before attackers can exploit them, protecting user assets and your platform's reputation.
01
Prevent Catastrophic Asset Loss
We simulate sophisticated attacks to find and fix critical vulnerabilities in private key storage, transaction signing, and seed phrase handling before they lead to irreversible financial loss.

Browser Extension Wallet Security
Frequently Asked Questions
Get clear answers on our methodology, timeline, and deliverables for securing your browser extension wallet.
We follow a hybrid methodology combining automated scanning with deep manual analysis. Our process includes: 1) Architecture Review of extension permissions, background scripts, and content script isolation. 2) Automated Static & Dynamic Analysis using custom tools to detect common Web3 vulnerabilities. 3) Manual Exploitation focusing on private key handling, transaction signing flows, phishing simulation, and cross-site request forgery (CSRF). 4) Post-Message & RPC Security testing for communication between the extension, dApps, and external sites. This approach has secured over $2B+ in user assets across 50+ wallet projects.
