Full-Stack Web3 Security¶
Audience: Web3 app security teams, frontend engineers, protocol security leads, wallet teams, and incident responders.
Smart contract security is only one layer. Many losses start in DNS, frontends, wallet-drainer UX, build pipelines, package compromise, analytics scripts, admin panels, and monitoring gaps.

Review Areas¶
- Domain registrar, DNSSEC, nameserver, email, CDN, and TLS posture.
- Frontend build provenance, hosting, CSP, dependency pinning, and third-party scripts.
- Wallet transaction simulation, spender approvals, typed data, chain IDs, and phishing resistance.
- API authentication, authorization, rate limiting, and tenant isolation.
- CI/CD secrets, deploy permissions, branch protection, and artifact integrity.
- Monitoring for domain takeover, frontend drift, contract events, admin actions, and anomalous flows.
Deliverable¶
Produce a full-stack security map that links every user asset to the systems that can change it: contracts, frontends, APIs, admin panels, cloud accounts, DNS, CI/CD, governance, multisigs, and external services.
