Coinbase Wallet & Extension

Welcome to Coinbase Wallet

Coinbase Wallet is a self‑custodial digital wallet launched originally in 2017 as a mobile application for iOS and Android, and later expanded into a standalone Coinbase Extension and Coinbase Chrome Extension. It provides a secure, intuitive way to access Web3: decentralized apps (dApps), DeFi protocols, NFTs, and multiple blockchain networks—all while keeping you fully in control of your private keys.

Rebuilt using React Native, Coinbase Wallet now shares a unified codebase across mobile and browser extension platforms. This ensures consistent, high‑quality feature rollout and UX across all devices. :contentReference[oaicite:2]{index=2}

The mobile experience includes dark mode by default, real‑time price charts, an integrated DeFi portfolio view, support for Solana and SPL tokens, NFT gallery, and cross‑chain token management on networks like Ethereum, Polygon, Base, Avalanche, and more. :contentReference[oaicite:3]{index=3}

About the Coinbase Wallet Extension

The Coinbase Wallet Extension, often referred to as the Coinbase Chrome Extension, brings Coinbase Wallet capabilities directly into Chrome and other Chromium‑based browsers such as Brave or Edge. With it, you can:

Interact with Web3 dApps like Uniswap, Compound, OpenSea, Aave, and more.
Store and manage Ethereum, ERC‑20 tokens, NFTs, and even some non‑EVM assets like Solana (via wrapped tokens).
Perform direct token swaps within the extension without visiting external services.
Sync with the mobile Coinbase Wallet for unified asset access. :contentReference[oaicite:4]{index=4}

Coinbase Wallet browser extension interface

Originally introduced in 2021 as a companion to the mobile app, Coinbase later upgraded the browser extension into a full standalone self‑custodial wallet — meaning you no longer need to confirm transactions via mobile unless you choose to link them. :contentReference[oaicite:5]{index=5}

Core Features: Wallet, Extension & Chrome Extension

Self‑Custody & Security

Both the Wallet app and the browser extension store private keys locally on your device. You’re in full control; Coinbase cannot access or recover your wallet. During setup you receive a 12‑word recovery phrase — store it offline securely. :contentReference[oaicite:6]{index=6}

Multi‑Chain & Asset Support

Supports Ethereum, Bitcoin (via wrapped or smart‑wallet support), Solana & SPL tokens, Polygon, Avalanche, Base, and other EVM‑compatible chains. You can view your NFTs, tokens, and even legacy holdings. :contentReference[oaicite:7]{index=7}

dApp Connectivity

Connect to decentralized applications directly in your browser via the **Coinbase Extension**, or via built‑in dApp browser on mobile. Access DeFi protocols, NFT marketplaces, gaming, social Web3 platforms, and more. :contentReference[oaicite:8]{index=8}

Token Swaps & Fiat On‑Ramp

Swap tokens natively inside the wallet. On mobile you can fund your Coinbase Wallet using debit cards, bank transfers, or via a linked Coinbase account (Coinbase Pay). Some of these features extend into the extension context too. :contentReference[oaicite:9]{index=9}

DeFi Portfolio & Price Charts

Track your DeFi investments and wallet balances via a clean dashboard, complete with price charts and network analytics. Available across both platforms. :contentReference[oaicite:10]{index=10}

Cross‑Platform Sync

Link your mobile Coinbase Wallet with the browser extension via QR code or recovery phrase. Once synced, assets and NFTs remain visible seamlessly across both. :contentReference[oaicite:11]{index=11}

Smart Wallet & Passkey Features

A “smart wallet” option leverages cloud‑based backups and biometric passkeys (FaceID/Fingerprint) to simplify device recovery. While more user‑friendly, it trades some aspects of traditional trustlessness. :contentReference[oaicite:12]{index=12}

Languages & Localization

Available in over 25 languages and supports local currencies to make the self‑custody experience accessible globally. :contentReference[oaicite:13]{index=13}

FAQ

1. What is the difference between Coinbase Wallet and Coinbase Chrome Extension?: Coinbase Wallet is the mobile self‑custody app, while Coinbase Chrome Extension is a browser plugin version that brings similar functionality to desktop. Both let you manage private keys, dApps, DeFi, and NFTs—but the extension is optimized for desktop, the app for mobile.
2. Can I use the Coinbase Extension without a Coinbase.com account?: Yes. The extension is standalone and non‑custodial. You don’t need a Coinbase.com account to use it—only a recovery phrase and/or password to restore or create a wallet. :contentReference[oaicite:14]{index=14}
3. How do I install and set up the Coinbase Wallet Chrome Extension?: Visit the official Chrome Web Store and search “Coinbase Wallet Extension”. Click “Add to Chrome”, follow the prompts to create or import a wallet, set a strong password, and securely store your 12‑word recovery phrase. :contentReference[oaicite:15]{index=15}
4. Is Coinbase Wallet safe to use?: Yes—when used correctly. Because it's self‑custodial, only you hold the keys. Never share your recovery phrase. Use strong passwords, enable 2FA (on Coinbase.com login if linked), and stay cautious of phishing attacks or fake browser extensions. :contentReference[oaicite:16]{index=16}
5. What assets and networks does Coinbase Wallet support?: It supports Ethereum, ERC‑20 and NFT standards, Solana & SPL tokens, Bitcoin via smart wallet or wrapped versions, and other EVM‑compatible chains like Polygon, Avalanche, Base, Binance Smart Chain, etc. :contentReference[oaicite:17]{index=17}
6. How do I sync my mobile Wallet with the browser Extension?: You can sync via QR code or by entering your recovery phrase in the extension. Once linked, your account and assets remain synchronized across devices. Alternatively, continue using WalletLink if you prefer mobile confirmations. :contentReference[oaicite:18]{index=18}
