Self-Custody Web3 Gateway

Bridge your browser to the decentralized web with full control of your private keys and assets.

Self-Custody Gateway

True Self-Custody

The Coinbase Wallet extension is a self-custody crypto wallet that brings the world of Web3 directly into your browser. Unlike the custodial Coinbase exchange where the platform holds your keys, this extension puts full control of your private keys and assets in your hands. With over one million users, it serves as a gateway to decentralized finance (DeFi), NFTs, and thousands of dApps across Ethereum and all EVM-compatible networks—including Avalanche, Polygon, and BNB Chain—plus native support for Solana and SPL tokens.

The most fundamental distinction is the self-custody model. When you install the extension and create a new wallet, you receive a 12-word Secret Recovery Phrase. This phrase is the master key to your funds; Coinbase does not store it, cannot recover it for you, and has no access to your assets. Your private keys are stored locally in your browser, encrypted by a password you set. This means you are your own bank—with all the freedom and responsibility that entails.
