Overview
What is Trust Wallet Extension?
Trust Wallet Extension is a browser-based companion to Trust Wallet’s mobile app. It brings secure private-key management, connected dApp browsing, and transaction signing to desktop browsers so users can interact with the wider Web3 ecosystem with confidence.
Why use the extension?
- Quick access to DeFi and NFTs without repeatedly entering private keys.
- Secure transaction signing localized in your browser.
- Seamless pairing with the Trust Wallet mobile app.
Key Features
Secure Key Storage (Local)
Private keys remain encrypted on your device. The extension never transmits private keys to servers — only signed transactions are shared with the network.
Easy dApp Connections
Connect to decentralized applications using the standard Web3 provider interface. Approve or reject permission requests and signatures from a clear, readable UI.
Multi-chain Support
Manage assets across multiple chains (Ethereum, BSC, Polygon, and many EVM-compatible networks) with intuitive chain-switching in the extension UI.
Best Practices
1. Backup your seed phrase
Store your seed phrase offline and never share it. If you lose it, account recovery is impossible.
2. Use a hardware wallet for large balances
For high-value holdings, connect a hardware wallet (supported models) to the extension for an extra layer of protection.
3. Verify dApp requests carefully
Read request details — token approvals should be as narrowly scoped as possible.
How to Install & Setup
- Open the official browser store and install the Trust Wallet extension.
- Create a new wallet or import an existing wallet using a seed phrase.
- Set a strong password and enable the extension’s lock features.
- Pair with your mobile Trust Wallet if desired.
Tips for Onboarding
Start with a small test transaction to ensure everything works. Keep the extension updated and review permissions periodically.
Use Cases
DeFi Trading and Yield Farming
Swap tokens, provide liquidity, and stake — all signed securely through the extension.
NFT Marketplaces
Sign listings and purchases directly from supported NFT sites while your keys stay offline and encrypted.
Developer Testing
Developers can use the extension to test dApp integrations in a real browser environment without exposing private keys.
Troubleshooting
Extension not connecting?
Check browser permissions, disable conflicting wallet extensions, and make sure the extension is unlocked before connecting.
Lost access?
Only restore via your 12/24-word seed phrase. Contact official support if you see suspicious behavior, but never share your phrase with anyone.
