Coinbase Wallet is a self-custody cryptocurrency wallet that empowers you to securely store your digital assets, explore decentralized applications (dApps), and manage your crypto portfolio. While the Coinbase exchange is renowned for its regulatory compliance and strong capital backing, the Wallet serves as its versatile extension, granting access to a broader Web3 ecosystem, including assets on the Base blockchain.
This guide will walk you through setting up your Coinbase Wallet, funding it, swapping tokens, and withdrawing funds, with a focus on practical, step-by-step instructions.
Creating Your Coinbase Wallet
To begin, download the Coinbase Wallet app from your device's official app store. Upon opening the app, you will be presented with two options: "Create a new wallet" or "I already have a wallet." For new users, select "Create a new wallet."
The setup process is streamlined for user convenience. You will be prompted to enable biometric authentication, such as Face ID, for enhanced security. Once completed, the app will automatically generate your new wallet.
A unique feature offered is the ability to claim a free, human-readable username. This is highly recommended. Instead of sharing a long, complex public address, you can use this username to receive funds, significantly reducing the risk of errors or falling victim to address poisoning scams, where malicious actors send tiny amounts from similar-looking addresses to confuse you.
To claim your username, simply tap "Claim my username," choose an available name, agree to the terms, and complete the process. Your wallet is now ready.
Adding Assets to Your Wallet: Funding via Base Chain
Your new wallet supports multiple blockchains. A popular and cost-effective network for transactions is Base, an Ethereum Layer-2 chain developed by Coinbase.
To receive assets, tap the "Receive" button within the app. You will see your wallet's address. A key point to understand is that this single address is compatible with any Ethereum Virtual Machine (EVM) chain, including Base, Avalanche (Avax), BNB Smart Chain, and Polygon. This means you can receive ETH and other compatible assets from these different networks at the same address.
For this guide, we will focus on funding your wallet with Base chain assets.
- Copy Your Wallet Address: In the Coinbase Wallet app, tap "Receive" and copy the provided address.
- Initiate Withdrawal from an Exchange: Log into your preferred cryptocurrency exchange (e.g., Binance, OKX). Navigate to the "Withdraw" or "Withdraw Crypto" section.
- Select Asset and Network: Choose ETH (Ethereum) as the asset you wish to withdraw. Critically, you must select the correct withdrawal network. Instead of the default Ethereum network (ERC20), you must manually select "Base" or "ETH-Base" as the network. This ensures your ETH is sent on the Base chain.
- Paste Address and Confirm: Paste your Coinbase Wallet address into the recipient field, enter the amount, review all details (especially the network), and confirm the transaction.
The same process applies for stablecoins like USDC. However, you must first ensure the exchange supports withdrawing USDC on the Base network. After purchasing USDC on the exchange, initiate a withdrawal, select USDC as the asset, choose the "Base" network, paste your wallet address, and confirm.
Your funds should arrive in your wallet after the network processes the transaction.
Securing Your Wallet: The Ultimate Priority
Before engaging in any transactions, securing your wallet is the most crucial step. Tap the "Backup wallet" option in the app.
You will be presented with your secret recovery phrase (a 12 or 24-word list). This phrase is the master key to your wallet and all assets within it. Anyone with these words can gain complete control.
- Manual Backup (Recommended): Write down each word in the exact order on a physical piece of paper. Store this paper in multiple secure locations, like a safe or safety deposit box. Do not store it digitally as a screenshot or in a text file, as this is vulnerable to hackers.
- iCloud/Cloud Backup: The app may offer to encrypt and back up your recovery phrase to your cloud account (e.g., iCloud for iOS). While convenient, this method's security is only as strong as your cloud account's security. Ensure you use a strong, unique password and two-factor authentication for your cloud service.
The app will also prompt you to set a separate, unique password for the wallet app itself. Remember this password. If you forget it, you can always regain access to your funds by importing your secret recovery phrase into another compatible wallet application like MetaMask or Trust Wallet.

Swapping and Discovering Tokens
Coinbase Wallet has a built-in swap function, allowing you to trade one token for another directly within the app.
- Tap the "Swap" or "Convert" button on the home screen.
- Select the asset you want to swap from (e.g., ETH on Base) and the asset you want to receive (e.g., USDC on Base).
- The app will automatically find the best available exchange rate from integrated decentralized exchanges (DEXs). Always ensure you are leaving enough ETH in your wallet to cover future transaction fees (gas).
- Review the transaction details, including the exchange rate and network fee, before confirming the swap.
The swap interface can also serve as a discovery tool, showing you popular tokens on the connected network, sorted by trading volume.
For more advanced discovery, you can use external tools like DexScreener to analyze trends on Base and other chains. If you find a token's contract address on such a site, you can paste it directly into the Wallet's swap interface to facilitate a trade.
Withdrawing Funds to an Exchange
To cash out or move funds back to a centralized exchange, the process is essentially the reverse of funding.
- Get Deposit Address from Exchange: Log into your exchange account and navigate to the "Deposit" or "Receive Crypto" section for the asset you want to deposit (e.g., ETH).
- Select Correct Network: It is absolutely vital to select the same network for deposit that you used for withdrawal. If you are sending ETH on the Base chain, you must select the "Base" network on the exchange to generate the correct deposit address. Sending to the wrong network will likely result in permanent loss of funds.
- Initiate Send from Wallet: In your Coinbase Wallet, tap on the asset you wish to send and select "Send." Paste the deposit address you copied from the exchange.
- Confirm and Send: Double-check that the address and network are correct. The wallet will typically display a verification checkmark for correctly formatted addresses. Confirm the transaction and pay the network gas fee.
The transfer will then be processed on the blockchain. You can track its status using a block explorer like Basescan by entering your transaction hash (TXID).
Frequently Asked Questions
What is the difference between Coinbase Exchange and Coinbase Wallet?
Coinbase Exchange is a centralized platform where you buy, sell, and trade crypto, with Coinbase acting as the custodian of your assets. Coinbase Wallet is a non-custodial (self-custody) wallet where you alone control your private keys and assets, and you can interact directly with blockchains and dApps.
Is it safe to back up my recovery phrase to iCloud?
While convenient, it introduces a risk factor. Your recovery phrase is encrypted, but its security is tied to your Apple ID's strength. If your iCloud account is compromised, your encrypted phrase could be targeted. A physical, offline backup is generally considered the most secure method.
I sent assets using the wrong network. What can I do?
Recovery is often impossible. Centralized exchanges control the private keys for their deposit addresses. If you send assets on an unsupported network, they may be irretrievably lost. Always perform a small test transaction first and triple-check the network selection at both the sending and receiving ends.
Why should I use the Base network?
Base, an Ethereum Layer-2, offers significantly lower transaction fees (gas fees) compared to the main Ethereum network. It also provides fast transaction times and seamless access to a growing ecosystem of dApps and tokens built on it.
Can I use my Coinbase Wallet recovery phrase in other wallets?
Yes. Your recovery phrase is a universal standard (BIP39). You can import it into other non-custodial wallets like MetaMask, Trust Wallet, or Ledger Live to access the same accounts and funds.
What happens if I lose my phone or uninstall the app?
As long as you have your secret recovery phrase, your funds are safe. You can simply reinstall the Coinbase Wallet app (or any other compatible wallet) on any device and use your phrase to restore full access to your assets and transaction history.
