Coinbase Wallet Extension

Explore Web3 Directly From Your Browser

The Coinbase Wallet Extension provides a convenient way to access Web3 experiences from your desktop browser. Designed for users who want to interact with decentralized applications, manage digital assets, and explore blockchain-based services, the extension brings wallet functionality into a familiar browsing environment.

With a browser wallet, users can connect to supported decentralized applications without repeatedly entering wallet information or leaving the website they are visiting. The extension can serve as an interface between your browser and supported blockchain networks, allowing you to review and authorize transactions when interacting with compatible Web3 services.

A Simple Way to Access Your Digital Assets

Managing digital assets should be straightforward. A browser-based wallet provides an accessible interface for viewing supported assets and interacting with blockchain networks from your computer.

Depending on the features and networks currently supported, users may be able to view asset balances, send and receive supported digital assets, connect with decentralized applications, and review transaction requests before authorizing them.

Blockchain transactions are generally recorded on their respective networks. Once a transaction has been submitted and confirmed, it may not be possible to reverse or cancel it. For this reason, carefully reviewing transaction information before approval is an important part of responsible wallet use.

Connect With Decentralized Applications

The Web3 ecosystem includes decentralized exchanges, marketplaces, games, financial applications, NFT platforms, and other blockchain-powered services. A compatible wallet extension can allow users to connect their wallet to these applications through their desktop browser.

When connecting to a decentralized application, take time to verify that you are visiting the intended website. Malicious websites can imitate legitimate services and may attempt to persuade users to approve unauthorized transactions or disclose confidential wallet information.

A wallet connection should never be treated as proof that a particular application is safe or trustworthy. Users should independently evaluate websites and smart contracts before interacting with them.

Take Control of Your Wallet Security

Wallet security begins with protecting access credentials and recovery information. Your recovery phrase and private keys can provide access to your assets and should therefore be treated as confidential.

Never share your recovery phrase or private keys with someone claiming to be a wallet representative, technical-support agent, community moderator, or security specialist. Legitimate support should not require you to disclose sensitive wallet credentials.

Users should also be cautious when installing browser extensions. Download wallet software only through verified sources and carefully check the publisher, website address, and installation details before proceeding.

Keeping your operating system, browser, security software, and wallet extension updated can also help reduce exposure to known security vulnerabilities.

Review Every Transaction Carefully

Before approving a blockchain transaction, review the information displayed by your wallet and the connected application.

Check the destination address, transaction amount, network, applicable fees, and any permissions being requested. Smart-contract interactions can sometimes involve permissions that allow an application to interact with particular assets.

If something looks unfamiliar or unexpected, do not approve the request until you understand what it does.

Remember that blockchain transactions can be difficult or impossible to reverse. Entering an incorrect address, selecting an incompatible network, or approving a malicious transaction could result in permanent asset loss.

Privacy and Web3

Blockchain networks can provide publicly accessible transaction information. Depending on the network and application, wallet addresses and transaction activity may be visible to other parties.

Connecting a wallet to a decentralized application may also allow that application to identify the wallet address involved in the interaction. Users should review the privacy policies and practices of websites and services before connecting their wallets.

Avoid sharing more personal information than is necessary when using Web3 services, and remain cautious when applications request information that appears unrelated to the service being provided.

Beware of Phishing and Impersonation

Cryptocurrency users can be targeted by phishing attempts, fraudulent websites, fake applications, and impersonation scams. Attackers may use familiar branding or urgent messages to convince users to reveal recovery phrases, sign transactions, or install malicious software.

Be especially careful with unsolicited messages, social-media accounts, advertisements, pop-ups, and links that request immediate action.

Always verify the website you are using before entering information or connecting a wallet. If you receive a suspicious support request, independently locate the provider's official support resources rather than following links supplied in the message.

Using Third-Party Services

Web3 applications, smart contracts, tokens, and other blockchain services may be developed and operated by independent third parties. Their availability, functionality, security, and terms may differ from those of the wallet itself.

Connecting a wallet to an external application does not necessarily mean that the wallet provider operates, controls, or endorses that application. Users should conduct their own research and understand the risks associated with any third-party service before interacting with it.
