1. The security model — what you must know
Security starts with the seed phrase. The extension stores the private keys locally, encrypted with a password chosen by the user. This model gives users full control but also full responsibility: no centralized recovery service can restore access if the seed phrase is lost. The extension provides a clear backup wizard at creation; follow that wizard carefully and store the recovery phrase offline in multiple secure locations.
2. Protecting your recovery phrase
Never store the seed phrase digitally (not in cloud notes, not in email). Ideally use a hardware wallet or write the words on paper kept in a safe or use a steel backup plate for fire/water resistance. Some users choose geographically distributed backups (e.g., two secure locations) to protect against local disasters. If you must record digitally for a short period, use an air-gapped device and delete the record permanently once the physical backup is created.
3. Phishing & malicious prompts
Phishing remains the most common threat vector. Malicious pages may mimic the extension’s UI and trick users into approving transactions or revealing recovery details. Always confirm the extension origin and never reveal the recovery phrase to sites or chat agents. If a website asks you for the seed phrase to "recover access", treat it as fraudulent. For extension safety, install from the official site or the verified browser store entry.
4. Using hardware wallets
For larger holdings, integrate a hardware wallet. Trúst Wãllet Exténsïon supports common hardware wallets through standard interfaces. Hardware devices keep the signing keys offline, greatly reducing risk. Even with hardware wallets, enforce the same diligence: maintain device firmware, check signing details shown on the device, and isolate hardware wallets when not in use.
5. Transaction approvals & allowances
When connecting to dApps, review token approvals, and avoid unlimited allowances. The extension surfaces approval details — take time to review what contract is being allowed to spend and set minimal allowances where possible. Use revocation tools to clear allowances that are no longer needed; such features are available via explorer tools and some wallet UIs.
6. Additional protective features
Enable password lock, set a short session timeout, and use browser profiles to compartmentalize accounts. Privacy-conscious users should consider a dedicated browsing profile for web3 activities. If you suspect a compromise, immediately move assets to a new wallet and rotate funds through a secure transfer using a trusted network and hardware signer.
