How to clear DApp browser cache in Trust Wallet? (Privacy Settings)

Understanding DApp Browser Cache in Trust Wallet

1. Trust Wallet’s built-in DApp browser stores temporary files including JavaScript bundles, HTML pages, and session cookies each time a decentralized application is accessed.

2. These cached assets improve load speed for repeated visits but may retain sensitive on-chain interaction traces such as wallet address exposure or transaction history fragments.

3. Unlike traditional web browsers, the DApp browser does not auto-purge cache upon app restart—retention periods depend on internal storage policies and user behavior patterns.

4. Cached data resides locally on the device and is never synced to cloud services or Trust Wallet’s backend infrastructure.

5. Some dApps inject dynamic scripts that persist across sessions, increasing the risk of fingerprinting or unintended state leakage during subsequent interactions.

Step-by-Step Cache Clearance Process

1. Open Trust Wallet and tap the DApp Browser icon located at the bottom navigation bar.

2. Tap the three-dot menu (⋮) in the top-right corner to reveal advanced options.

3. Select Settings, then navigate to Privacy & Security.

4. Scroll down to find Clear Browsing Data and tap it.

5. Toggle on Cached Images and Files and Cookies and Site Data. Leave other options unchecked unless explicitly required.

6. Confirm with Clear Data. The process completes instantly without requiring app restart.

Impact of Cache Deletion on Active DApp Sessions

1. All active login states within dApps will be invalidated, forcing re-authentication via wallet connection prompts.

2. Custom network configurations previously saved per dApp domain are preserved, as they reside outside the cache layer.

3. Token balances displayed inside dApp interfaces may temporarily show zero until the next on-chain sync completes.

4. Gas estimation logic may reset to default values if custom RPC endpoints were overridden by cached provider settings.

5. No private keys, seed phrases, or wallet addresses are affected—cache deletion operates exclusively on frontend-rendered data.

Privacy Risks Associated With Retained Cache

1. Third-party analytics scripts embedded in dApp frontends can reconstruct user activity timelines using cached timestamps and local storage artifacts.

2. Session tokens stored under localStorage or sessionStorage may remain accessible to malicious iframe injections if not purged.

3. Cached ABI definitions used for contract interaction could expose historical contract calls tied to specific wallet addresses.

4. Browser fingerprinting vectors like canvas rendering hashes or WebGL parameters may persist in cached JS contexts.

5. Cross-site tracking becomes possible when multiple dApps share common CDNs whose resources are reused from cache without origin isolation.

Frequently Asked Questions

Q: Does clearing cache disconnect my wallet from all dApps?A: Yes. Each dApp loses its active connection state and requires manual re-connection via the wallet interface.

Q: Will my transaction history inside Trust Wallet disappear after cache clearance?A: No. On-chain transaction records are immutable and stored separately from browser cache. Only frontend display caches are removed.

Q: Can I automate cache clearing before every dApp visit?A: Trust Wallet does not support scheduled or trigger-based cache purging. Manual execution remains the only supported method.

Q: Is there a way to clear cache for one dApp only instead of all?A: No. The current Trust Wallet implementation applies cache deletion globally across all visited domains without granular domain-level control.
