Security Features

Security is one of the most important aspects of using a non-custodial wallet.

Recovery Phrase

When creating a wallet, users receive a recovery phrase that serves as the ultimate backup for wallet access.

Best practices include:

• Write the recovery phrase on paper.

• Store it securely offline.

• Never photograph or scan it.

• Never upload it to cloud storage.

• Never share it with anyone.

Anyone who knows the recovery phrase may be able to access the wallet and its assets.

Password Protection

The extension is protected by a local password that helps prevent unauthorized access from the same computer. Users should create a strong and unique password.

Transaction Verification

Before broadcasting a blockchain transaction, the extension displays important information for review.

Users should carefully verify:

• Recipient address

• Asset type

• Transaction amount

• Network fees

• Requested permissions for smart contracts

Carefully reviewing every transaction helps reduce mistakes and improve security.

Installing Coinbase Wallet Extension

The installation process is generally straightforward:

1. Install the extension from the official browser extension marketplace.

2. Add it to your supported browser.

3. Launch the extension.

4. Create a new wallet or import an existing wallet.

5. Securely record the recovery phrase.

6. Create a strong password.

7. Begin managing supported digital assets.

Always install browser extensions from official sources to reduce security risks.

Connecting to Decentralized Applications

Connecting to a compatible decentralized application typically involves the following steps:

1. Visit the application's official website.

3. Choose Coinbase Wallet.

4. Review the connection request.

Developing safe habits is essential because blockchain transactions are generally irreversible.

Many wallet security issues result from preventable errors.

Avoid:

• Sharing recovery phrases.

• Installing unofficial wallet extensions.

• Connecting to suspicious websites.

• Approving unfamiliar smart contract permissions.

• Sending cryptocurrency to unsupported blockchain networks.
