Coinbase Wallet is a self-custody crypto wallet developed by Coinbase that allows users to store digital assets, interact with decentralized applications (dApps), and explore the Web3 ecosystem directly from their browser. The Coinbase Wallet extension expands these capabilities by providing a secure browser-based interface for managing cryptocurrencies and connecting to DeFi platforms, NFT marketplaces, and blockchain games.
Unlike custodial exchange accounts, Coinbase Wallet gives users full control over their private keys and funds. This makes it a popular choice for individuals seeking greater ownership, privacy, and flexibility in the decentralized economy.

After installing the extension, users can:
During wallet creation, a 12-word recovery phrase is generated. This phrase is the master key to your wallet and must be stored securely offline.
Private keys are encrypted and stored locally in your browser. Every transaction must be manually approved before it is processed on the blockchain.

Malicious browser extensions or malware could compromise security. Keep your browser environment secure.
To maximize security when using the Coinbase Wallet extension:
Security in self-custody wallets depends heavily on user responsibility.
It’s important to distinguish between:

However, self-custody requires responsibility. Protecting your recovery phrase, verifying transactions, and practicing safe browsing habits are essential for maintaining control of your assets.
For users seeking a secure, user-friendly gateway to DeFi, NFTs, and blockchain applications, the Coinbase Wallet extension provides a reliable and flexible solution in the evolving world of cryptocurrency and decentralized technology.
