Securely trade, manage, and explore digital assets directly from your browser with the official Coinbase® Extension. Self-custody, DeFi, NFTs, and multi-chain management — all in one place.
Get StartedThe Coinbase® Extension is a lightweight, self-custody browser wallet designed to connect users to decentralized applications without compromising security. Unlike custodial wallets, it ensures your private keys remain under your control, allowing seamless interaction with Ethereum, Solana, Polygon, and other supported networks.
This extension injects wallet functionality directly into your browser, enabling instant token swaps, NFT collection management, DeFi access, and transaction signing without leaving the web page.
Through Coinbase® Extension, users can interact safely with smart contracts, execute multi-chain transactions, and manage portfolio balances across networks with clarity and confidence.
Installation is simple: add the extension from the official browser store, create a new wallet or import an existing one using your recovery phrase, and set a secure password. Enable hardware wallet pairing or system-level protections for added security.
Once installed, connect to trusted dapps, review transaction details, and approve actions securely. Your assets remain fully in your control.
Manage multiple networks like Ethereum, Solana, and Polygon. Switch seamlessly between networks without reconnecting or losing access.
Instantly swap tokens across supported chains. The interface highlights network fees and price impact clearly before confirmation.
View, collect, and transfer NFTs. Track ownership across marketplaces and networks directly within the extension.
Interact with lending, staking, and yield farming platforms. Approve transactions with full transparency and detailed gas/fee information.
Manage site access, revoke token approvals, and prevent unnecessary spending allowances for enhanced security.
Export, verify, and securely store your recovery phrase. Consider paper or metal backups for long-term asset safety.
Ownership comes with responsibility. Keep software updated, avoid phishing sites, and never share your recovery phrase. Verify smart contracts before interacting and use hardware wallets for large balances.
Periodic review of token approvals and connected dapps reduces exposure. Always use official stores for installation and updates.
1. Open your favorite dapp and connect the extension.
2. Review transaction details, gas fees, and network before signing.
3. Confirm the transaction, then track the status until finalized.
This workflow minimizes errors and maximizes security while interacting with decentralized networks.
Q: Is the Coinbase® Extension custodial? No. The extension is self-custody. Only you control the private keys.
Q: Can I use it across multiple browsers or devices? Yes. Import your wallet using the recovery phrase on each trusted device.
Q: Does it support NFTs and DeFi? Absolutely. You can manage collectibles and access decentralized applications securely.
Q: How are network fees handled? Fees go to validators or miners. The extension shows estimates and lets you adjust speed versus cost.
If a dapp fails to connect, try switching networks or reconnecting the wallet. For stuck transactions, adjust gas or wait for network congestion to ease. Ensure token addresses are correct when adding custom assets.
Always reinstall from official sources and double-check the publisher.
