Your Secret Recovery Phrase is the backup key to your wallet.
Important security rules:

Never enter it on suspicious websites
Anyone with access to your recovery phrase can fully control your assets.
Once setup is complete, users can:
Send and receive crypto

Manage NFTs
Explore decentralized finance platforms
The extension acts as a secure connection layer between your browser and blockchain applications.
When visiting a supported dApp:
The application requests wallet access
Coinbase Wallet asks for user approval
Transactions require manual confirmation
Approved transactions are signed securely and sent to the blockchain
This process ensures users remain in full control of wallet activity and permissions.
The wallet is beginner-friendly while still offering advanced features for experienced users.
Users maintain full control over private keys and crypto holdings.
Thousands of decentralized applications support Coinbase Wallet integration.
Users can sync their browser extension with the Coinbase Wallet mobile app for easier access across devices.
Some users may encounter:

Failed transactions
Most issues can be resolved by:
Restarting the browser
Updating the extension

To maximize wallet safety:
Use only official Coinbase Wallet software
Verify website URLs carefully
Avoid suspicious links and phishing websites
Never share your Secret Recovery Phrase
Consider using a hardware wallet for large holdings
Coinbase support will never ask for your recovery phrase.
It is important to understand the difference between the two services:
Centralized crypto trading platform
Coinbase manages custody of funds
Self-custody Web3 wallet
Users fully control private keys and assets
The wallet extension gives users more control and direct access to decentralized applications.
