Coinbase Wallet – Buy and Sell Bitcoin, Ethereum, and More

Coinbase Wallet is a self‑custodial crypto wallet that gives you full control over your digital assets. With it, you can buy, sell, store, swap, explore Web3 apps, manage NFTs, and much more—all securely and without having to hand over your private keys to anyone else. Whether you’re a newcomer to crypto or an experienced user, this guide will walk you through how to use Coinbase Wallet to buy and sell cryptocurrencies, and how to keep your assets safe.

What is Coinbase Wallet?

Unlike a custodial exchange, Coinbase Wallet is non‑custodial (you control the keys) and intended to work across many blockchains. It supports Ethereum, Solana, Polygon, other EVM‑compatible chains, and many tokens and NFTs. :contentReference[oaicite:0]{index=0}

You can access it via a mobile app (iOS and Android), and via browser extension. It’s meant to let you hold crypto, send & receive tokens, use decentralized apps (dApps), participate in DeFi, collect NFTs, and more. :contentReference[oaicite:1]{index=1}

How to Buy Crypto with Coinbase Wallet

Buying crypto using Coinbase Wallet is easy, especially if you're combining it with the Coinbase.com service. Here's how you can do it:

1. Open your Coinbase Wallet app (or extension) and ensure it’s connected to a payment method or linked to your Coinbase.com account if that feature is enabled. :contentReference[oaicite:2]{index=2}
2. Select the crypto you want to buy, for example, Bitcoin (BTC) or Ethereum (ETH). :contentReference[oaicite:3]{index=3}
3. Choose your payment method. This might be a bank account, debit/credit card, or supported local payment method. Coinbase Wallet supports buying crypto with fiat in many countries. :contentReference[oaicite:4]{index=4}
4. Review fees, conversion rates, and confirmation screens. Double check you’re buying the correct asset. Then confirm the purchase. The purchased crypto will land in your wallet. Note that network fees (gas) apply. :contentReference[oaicite:5]{index=5}
5. (Optional) If you have linked to Coinbase.com, you may also transfer directly between your Coinbase.com account and your Coinbase Wallet for easier management. :contentReference[oaicite:6]{index=6}

How to Sell or Swap Crypto via Coinbase Wallet

Selling or swapping crypto from your wallet is also straightforward:

• Use the “Swap” function in the Wallet to exchange one token for another directly in the app, across supported networks. It uses DEX (decentralized exchange) liquidity. :contentReference[oaicite:7]{index=7}
• If selling to fiat, you’d typically need to move crypto out of your non‑custodial wallet into a service like Coinbase.com or another exchange that supports withdrawals to your bank or other fiat off‑ramps. :contentReference[oaicite:8]{index=8}
• Set your slippage tolerance, confirm network fees, and double-check transaction details (amounts, destination addresses). Swaps and sales incur gas fees depending on the blockchain. :contentReference[oaicite:9]{index=9}
