Notably, it also supports the Solana network for sending and receiving SPL tokens .

1. Installation

Navigate to the Chrome Web Store and search for "Coinbase Wallet extension." Look for the official extension published by "Toshi Holdings Pte. Ltd." (Coinbase's entity) to ensure authenticity . Click "Add to Chrome" to install it .

Security: How to Stay Safe (Crucial Read)

  • Beware of Fakes: The crypto space is unfortunately a target for bad actors. Recently, security researchers have identified malicious browser extensions impersonating Coinbase and other major wallets to steal credentials . Always double-check the developer's name and the number of users before installing.
  • Never Share Your Seed Phrase: No legitimate support team, including Coinbase, will ever ask for your 12-word recovery phrase.
  • Use a Hardware Wallet: For large portfolios, consider connecting a Ledger device to the extension to sign transactions offline .

Coinbase Wallet vs. Coinbase.com

It is important to distinguish between the two:

  • Coinbase.com is a centralized exchange where you buy and sell crypto with fiat currency.
  • Coinbase Wallet extension is a self-custody browser extension for interacting with dApps and holding your own keys .

You can use both together—buying ETH on Coinbase.com and then sending it to your self-custody Wallet extension to use in DeFi.
