Coinbase® Wallet: Your Complete Guide to Self-Custody & Web3 Access

Coinbase® Wallet is a non-custodial cryptocurrency wallet that gives you full control over your digital assets while seamlessly connecting you to decentralized apps (dApps), NFTs, and DeFi protocols. Unlike the Coinbase® exchange, this standalone product ensures you own your private keys – making it the secure bridge between traditional finance and Web3.
