The Coinbase Extension is a browser-based cryptocurrency wallet that allows users to securely store digital assets, manage tokens, and interact with decentralized applications (dApps) directly from their web browser. Designed as part of the Coinbase Wallet ecosystem, the extension gives users full control over their crypto while enabling seamless access to Web3 platforms, decentralized finance (DeFi), NFTs, and blockchain-based services.
Unlike centralized exchange accounts, the Coinbase Extension is a non-custodial wallet, meaning users control their private keys and funds without relying on third parties.
The Coinbase Extension is a browser extension wallet linked to Coinbase Wallet, not the Coinbase exchange itself. It runs locally in your browser and acts as a secure interface for interacting with blockchain networks and Web3 applications.
The extension supports Ethereum and other EVM-compatible blockchains, allowing users to connect to thousands of decentralized websites without creating traditional accounts.
Once installed, the Coinbase Extension stores encrypted private keys locally on your device. When you visit a Web3-enabled website, the extension prompts you to approve wallet connections or transactions.
All sensitive actions—such as sending funds or approving smart contracts—require user confirmation. Private keys never leave your device, ensuring full ownership and control of assets.
Users maintain complete ownership of their crypto assets. Coinbase cannot access funds or reset wallet credentials.
The extension allows direct connections to decentralized exchanges, NFT marketplaces, blockchain games, and DeFi protocols.
Coinbase Extension supports Ethereum by default and allows users to add networks such as Polygon, Arbitrum, Optimism, Avalanche, and other EVM-compatible chains.
Users can view balances, manage ERC-20 tokens, and store NFTs securely within the extension interface.
Every transaction must be reviewed and approved manually, providing transparency and reducing the risk of unauthorized actions.
Installing the Coinbase Extension is straightforward:
Visit the official Coinbase Wallet website
Select the browser extension option
Redirect to the official browser extension store
Click Add to Browser and confirm
Pin the extension for easy access
Always ensure you are installing the extension from official sources to avoid phishing or fake versions.
Create a New Wallet
After installation, users can create a new wallet by setting a strong password. This password protects local access only.
Backup Your Recovery Phrase
The extension generates a 12-word recovery phrase, which is essential for restoring your wallet if you lose access. This phrase should be written down and stored securely offline.
Import an Existing Wallet
Users can also import an existing wallet using a recovery phrase to regain access to their funds.
Coinbase does not store recovery phrases or private keys.
With the Coinbase Extension, users can:
Send and receive cryptocurrencies
Connect to Web3 and DeFi applications
Approve smart contract interactions
Manage multiple wallet accounts
Switch between blockchain networks
View transaction history
The extension automatically detects when a website requests wallet access and asks for user approval.
It’s important to distinguish between the two:
Coinbase Extension Coinbase Exchange Non-custodial wallet Centralized exchange User controls keys Coinbase controls keys Web3 & dApps Trading & fiat on/off-ramps Browser-based Web & mobile platform
The extension is designed for decentralized usage, not traditional exchange trading.

Encrypted local key storage

Site permission management
Never share your recovery phrase
Verify website URLs before connecting
Avoid suspicious pop-ups or fake airdrops
Lock the extension when not in use

For large balances, combining the extension with a hardware wallet is recommended.
