THE BIG PICTURE

A small extension.
A different way
to connect.

A wallet extension can act as a bridge between your browser and decentralized applications. Understanding that bridge is the first step to using it with confidence.

Read the practical field guide

01 CONNECTION

Your browser, with permission

Choose when a site can request a wallet connection. A connection is not the same as approving every action.

02 CLARITY

Review before you sign

Pause to check the network, destination, and request details before you approve a transaction or signature.

03 CONTROL

Self-custody means responsibility

Protect recovery information offline. Anyone who asks you to reveal it should be treated with suspicion.

A BETTER DEFAULT

Slow down.
Look closer.

On-chain actions can be difficult or impossible to reverse. Treat wallet prompts like a final confirmation—not routine pop-ups to click through.

Confirm you are on the intended website and network.
Read the transaction details before approving.
Keep your recovery phrase private and offline.

Getting started with Coinbase Wallet Extension

A practical primer for making your first browser-based Web3 connection more intentional.

FIELDNOTE 001WEB3 / WALLET BASICS

A browser wallet extension lets you connect a wallet to decentralized applications without leaving your browser. Think of it as a permission layer: a site may request a connection, but you decide whether to grant it. Find the extension through Coinbase’s official website or a verified browser-store listing, and check the publisher carefully. Lookalike extensions are a common way to target people exploring crypto.

After setup, learn the wallet’s recovery and security options. A recovery phrase can restore access, so store it privately and never share it with anyone. No legitimate helper needs your phrase. When an app asks to connect, confirm you recognize the site and understand what the connection allows. Before approving a transaction, read the network, destination, permissions, and fee details. If a request is confusing or unusually urgent, pause and check official documentation.

Wallets help you explore decentralized applications and manage digital assets, but they do not remove risk. Transactions may be irreversible, prices fluctuate, and malicious links can imitate familiar services. Keep your browser and devices updated, and review connected apps regularly. Never invest more than you can afford to lose. Self-custody offers greater control, alongside greater responsibility; careful habits are part of using it well.
