Navigating the world of decentralized finance (DeFi) and managing a diverse cryptocurrency portfolio requires a reliable and functional wallet. The Coinbase Wallet is a popular self-custody option that gives you complete control over your digital assets. A key feature of this wallet is the ability to manually add custom tokens that may not appear in its default list.
This guide provides a clear, step-by-step tutorial for adding any custom token to your Coinbase Wallet, ensuring you can track and manage all your holdings in one secure place.
Understanding Coinbase Wallet and Custom Tokens
The Coinbase Wallet is a self-custody, hot wallet that allows you to store your own private keys and manage a wide array of cryptocurrencies and non-fungible tokens (NFTs). Unlike the main Coinbase exchange account, the wallet is a separate product that emphasizes user control and direct interaction with blockchain applications.
A custom token is any digital asset issued on a blockchain that is not automatically recognized or displayed by your wallet's default interface. This is common with newly launched tokens, lesser-known altcoins, or certain project-specific assets. Adding them manually requires specific information to ensure the wallet can correctly track the token on its native blockchain.
Prerequisites for Adding a Custom Token
Before you begin the process, ensure you have the following ready:
- The Coinbase Wallet App: Installed and set up on your mobile device, or access to the browser extension. Your wallet must be fully secured with a recovery phrase.
- A Small Amount of Native Cryptocurrency: You need a small amount of the blockchain's native currency (e.g., ETH for Ethereum, MATIC for Polygon) to pay for the gas fee required to add the token. This is a network transaction fee, not a fee charged by Coinbase.
- The Correct Token Contract Address: This is the most critical piece of information. It is a unique string of letters and numbers that identifies the token on its blockchain.
Crucial Warning: Always obtain the contract address from an official and verified source, such as the project's official website, documentation, or a reputable blockchain explorer like Etherscan. Never use a contract address from an unverified social media message, email, or unofficial website, as this is a common method scammers use to steal funds.
You may also need the Token Symbol (e.g., UNI) and Token Decimal (often 18), but the contract address is the primary requirement, as the wallet can often auto-populate the other details.
Step-by-Step Guide to Adding a Custom Token
Follow these steps to manually add a token to your Coinbase Wallet.
Step 1: Open Your Coinbase Wallet
Unlock your Coinbase Wallet mobile app or browser extension using your chosen security method (biometrics, PIN, etc.).
Step 2: Navigate to the 'Assets' Tab
Once inside the wallet, ensure you are on the main screen that displays your current portfolio of assets. This is typically the default "Assets" tab.
Step 3: Access the Token Addition Menu
Look for the "Add tokens" or "Import tokens" button. This is usually located in the top-right corner of the Assets tab (often an icon with a "+" or a list). Click or tap on it.
Step 4: Switch to the 'Custom Token' Tab
The wallet will likely present you with a list of popular tokens you can add with a single tap. Since you are adding a custom asset, you need to find and select the option that says "Custom token", "Import tokens", or something similar.
Step 5: Select the Correct Network
Blockchains like Ethereum, Polygon, and Arbitrum all host tokens. You must first select the correct network or blockchain on which your custom token exists. The wallet will typically have a dropdown menu to choose from various networks like Ethereum Mainnet, Polygon, Avalanche, etc. Selecting the wrong network will result in the token not appearing.
Step 6: Enter the Token Contract Address
This is the most important step. Carefully paste the correct token contract address you obtained from a verified source into the designated field. As you paste the address, the wallet will often automatically attempt to fetch and fill in the Token Symbol and Token Decimal fields.
Step 7: Confirm and Add the Token
Double-check that all the populated information is correct, especially the token symbol. If the details look accurate, confirm the action by tapping "Add custom token" or "Import". You may be prompted to approve a small gas fee to complete this on-chain action.
Step 8: View Your New Token
Once the transaction is confirmed by the network, you will be returned to your main Assets tab. Your newly added custom token should now be visible in your portfolio list, showing its current balance and value.

Troubleshooting Common Issues
- Token Not Showing Up? First, confirm you are on the correct blockchain network in your wallet settings. Then, verify that you used the exact, correct contract address without any errors.
- Incorrect Balance? Token balances and values are pulled from the blockchain. If the value seems wrong, it could be a display issue that resolves itself, or you may have added a fake token. Re-check the contract address.
- "Invalid Address" Error? This means the string you entered is not a valid contract address format for that network. Ensure you copied and pasted it perfectly.
Best Practices for Security
Managing custom tokens comes with added security responsibilities.
- Verify, Then Verify Again: Always double-check contract addresses on a block explorer before importing. A single wrong character can lead to irreversible loss.
- Beware of Dusting Attacks: Sometimes, you may receive unknown tokens in your wallet. Do not interact with them (don't try to sell or send them), as they can be malicious. You can usually just hide them from view.
- Understand Token Permissions: Interacting with a smart contract (e.g., to swap a token) often requires granting it spending permissions. Only grant permissions to contracts you trust completely.
Frequently Asked Questions
Why can't I see my token in Coinbase Wallet after adding it?
The most common reasons are being on the wrong network within your wallet settings or having used an incorrect token contract address. Go back to the import process and verify both the network and address meticulously.
Is there a fee to add a custom token?
Yes, adding a custom token requires a blockchain transaction to update your wallet's interface, which incurs a network gas fee paid in the native currency of that blockchain (e.g., ETH, MATIC). Coinbase itself does not charge a fee for this action.
Can I remove a custom token I added?
Yes, you can typically hide tokens from your main view. In your Assets list, there is often an option to "Hide token" or manage your visible assets. This does not remove the token from your wallet address on the blockchain; it simply stops displaying it in your app's interface.
What is the difference between Coinbase and Coinbase Wallet?
Coinbase is a centralized cryptocurrency exchange (CEX) where the company custodies your assets. Coinbase Wallet is a separate, self-custody software wallet where you, and only you, control the private keys and assets. They are two distinct products.
What should I do if I added a scam token?
If you have only added the token and not interacted with it further (e.g., approved it for spending), your risk is generally low. Simply hide the token from your view. However, if you approved a malicious smart contract, you should revoke those permissions using a tool like Etherscan's Token Approval feature.
Can I send and receive custom tokens after adding them?
Absolutely. Once successfully added, the token functions like any other asset in your wallet. You can use your public wallet address to receive more of that token and can send it to others, provided you have the necessary gas fees for the transaction.
