Web3 Privacy Threat Model
Map common privacy leak paths and define practical mitigations for individuals and teams.
Primary Leak Sources
- • Address clustering across transactions can reveal a user's identity profile.
- • Front-end analytics and third-party scripts may correlate wallet behavior with device fingerprints.
- • Repeated gas patterns and interaction timing can expose user routines.
Mitigation Baseline
- • Segment identities by purpose: one wallet for public actions, one for private operations.
- • Use privacy-focused RPC endpoints and minimize script-heavy dashboards.
- • Avoid publishing exact wallet balances and transaction timelines in public channels.
Operational Controls
- • Define incident response steps for doxxing, phishing, and approval abuse.
- • Audit exposed addresses and rotate operational wallets after major incidents.
- • Run monthly reviews of on-chain and off-chain metadata exposure.
