Extension

Coinbase Wallet Extension — Secure crypto, right in your browser

Manage your crypto, NFTs, and dApp connections with a fast, privacy-first browser extension. Built for clarity and security, the Coinbase Wallet Extension puts full control of your private keys on your device while making decentralized experiences simple and familiar.

Non-custodial & private

Only you hold your private keys. The extension stores encrypted keys locally and never transmits them to third-party servers — you remain in control of funds and identity.

Easy dApp connect

Quickly connect to decentralized apps (DeFi, NFT marketplaces, games) using secure connection flows and per-site permissions you can revoke at any time.

Multi-asset support

Hold ETH, ERC-20 tokens, NFTs, and multiple EVM-compatible chain assets. Token balances and transaction histories are displayed clearly inside the wallet.

Built-in swap & activity

Swap tokens directly in the extension with transparent rates and slippage controls — plus a clear activity feed so you always know what you approved and when.

How it works

After installation you create (or import) a wallet using a secure seed phrase. The extension encrypts your data locally and requires a password or biometric unlock to sign transactions. When you visit a dApp, the extension shows a connection prompt with clear metadata and requested permissions — you decide what the site can access.

Security highlights

  • Local encryption of seed and keys with optional hardware wallet support.
  • Granular permission model for connected websites.
  • Transaction previews with gas and destination details before signing.
  • Recovery using a 12/24-word seed phrase and optional encrypted cloud backup (opt-in).

Who it’s for

Whether you’re trading, collecting NFTs, experimenting with DeFi, or building on web3, the extension is designed for people who want a secure, simple gateway to blockchain apps without sacrificing control. It’s for beginners who need a friendly experience and advanced users who want fine-grained controls.
