THE SELF-CUSTODY FIELD GUIDE
A clear-eyed introduction to Coinbase Wallet Extension—how it connects you to decentralized apps, what to look for, and how to stay in control along the way.
WALLET BASICS, WITHOUT THE NOISE
A browser wallet extension can help you manage supported digital assets and connect to decentralized applications (dApps) from your desktop. Think of it as a bridge: you choose when to connect, what to review, and whether to approve each action.
That access comes with responsibility. A wallet is not a bank account, a guarantee of safety, or a substitute for careful decisions. The best first step is understanding what the extension does—and what stays in your hands.
Understand the connection flowFROM BROWSER TO BLOCKCHAIN
A wallet extension makes Web3 interactions easier to reach. It doesn't make every interaction safe by default.
Visit a dApp through a source you trust. Connect only when you understand why it needs wallet access.
Check transaction details, network, destination, fees, and any permissions before moving forward.
If something feels unclear, reject the prompt and investigate independently. There is no need to rush.
A connection is not the same as a transaction approval. Review each request separately.
A FEW GOOD HABITS
Practical habits can help you avoid common risks. They cannot eliminate every risk or guarantee recovery of lost assets.
See the getting-started checklistSelf custody gives you control of your wallet credentials. It also means protecting your recovery phrase is entirely your responsibility.
Review the network, destination, and requested permissions before signing. A familiar-looking prompt is not proof that a request is safe.
Use trusted sources to find decentralized apps, connect only when needed, and revisit connected-site permissions regularly.
A PRACTICAL INTRODUCTION
A browser wallet extension can make it easier to explore Web3 from your desktop. After installing Coinbase Wallet Extension from an official source, take time to understand how wallet access works before connecting to a decentralized application. Your wallet can help manage supported digital assets and approve blockchain transactions, while your private credentials remain under your control.
That control is valuable, but it also brings responsibility. Store your recovery phrase securely offline, and never share it with a person, website, or support representative. Anyone who obtains it may be able to access your wallet. Use a unique device passcode, keep your browser and extension updated, and be wary of unsolicited links or messages promising rewards.
When a dApp requests a connection or transaction, slow down. Confirm the website address, network, recipient, token, and fees. Read permission requests rather than treating them as routine pop-ups. If anything is unclear, decline and verify the details through trusted documentation. A wallet connection does not guarantee that an app is legitimate, and blockchain transactions may be irreversible. Begin with small, deliberate steps, keep only what you can afford to lose in self-custody, and remember: careful review is one of your strongest tools.
A CALM START IS A GOOD START
Use this short checklist before exploring. Always verify current product details with official Coinbase resources.

BEFORE YOU CONNECT
No. A browser wallet is designed for self-custody and Web3 interactions. It is distinct from an exchange account, which may have different services, controls, and terms.
No. Keep your recovery phrase private. Do not enter it into a site you reached through a message or share it with anyone claiming to offer support.
Not necessarily. Connecting can allow an app to interact with your wallet, while individual transactions and permissions require separate review. Read every prompt carefully.
