Coinbase Wallet Extension

Securely manage your crypto, NFTs, and dApp connections — directly from your browser.

One extension. Complete control.

Coinbase Wallet Extension gives you a private key-controlled wallet that stays with you — not with a website. Connect to decentralized apps, sign transactions, and keep your keys safe with industry-leading security features.

Why choose the Wallet Extension?

Private key ownership

You're in control. Your seed phrase and private keys remain in your browser extension and can be exported anytime.

Seamless dApp connections

Connect to marketplaces, games, and DeFi protocols with a single click — approve only the permissions you want to share.

Fast transaction signing

Optimized signing flow for quick confirmations without leaving the page — supports EVM and popular L2 networks.

Security & privacy — built in

Security is the foundation of your wallet. The Coinbase Wallet Extension uses a layered approach: local encryption, optional hardware-wallet integration, and user-controlled permissions keep your assets protected while giving you the flexibility modern crypto requires.

  • Local encryption: Your seed and keys are encrypted on your device and protected by your chosen password.
  • Hardware wallet support: Connect Ledger or Trezor to add an extra layer of signature security.
  • Permissioned connections: Each dApp request shows the exact data and token permissions; you decide what to share.
  • Open-source components: Core components are open for audit to give the community visibility into critical code.

Getting started — 3 simple steps

  1. Install the extension from your browser store.
  2. Create a new wallet or import an existing seed phrase.
  3. Connect to your favorite dApps and start interacting securely.

Frequently asked questions

Is my seed phrase stored on Coinbase?

No. The seed phrase is created and encrypted locally in your browser extension — Coinbase (the company) does not have access to your private keys unless you explicitly choose to back up to a cloud service managed by Coinbase.

Can I use multiple wallets?

Yes. The extension supports multiple wallet profiles. Each profile stores its own keys and settings so you can separate funds for different use cases.

What happens if I lose my device?

As long as you have your seed phrase backed up, you can restore your wallet on any compatible device. Store your seed phrase offline in a secure place.
