How to Buy NOX in Base App

1. Open Base App or the Coinbase Wallet extension

‍

Open Base App on mobile or open the Coinbase Wallet extension in your browser.

‍

Make sure Ethereum is the active network.

‍

If it is not, change the network at the top of the screen.

‍

‍

Add ETH to your Base App wallet

‍
Base App does not include a direct buy button inside the extension.

‍
You can fund the wallet in two ways:

‍

‍

Use the Receive button: Tap Receive, copy your Ethereum address, and send ETH from an

exchange such as Coinbase, Binance, OKX, Bitget, or any wallet you already use.

‍

Use Base App mobile: On mobile you may see Buy through Coinbase Pay in supported regions. If shown, you can buy ETH with card or local methods.
Once the ETH transfer confirms on Ethereum, your balance updates.

‍

Open the Swap tool

‍

In the main screen, tap Swap.

‍

The form loads with From set to ETH if you have ETH in your wallet.

‍

‍

2. Search for NOX by contract
‍

In the To field, tap the token selector.

‍

Paste the NOX contract address into the search box:
0x0a26c80Be4E060e688d7C23aDdB92cBb5D2C9eCA

‍

‍

Base App detects NOX.

‍

Tap NOX to lock it into the swap form.

‍

Set slippage to 3–5% so the swap can pass the transfer tax.

3. Complete the swap

‍

Enter the amount of ETH you want to trade.

‍

Tap Preview Swap.

‍

Review the route and fees.

‍

Tap Confirm.

‍

Approve the transaction inside Base App when asked. The app broadcasts the swap on Ethereum.

‍

4. Check your NOX balance

‍

Return to your main asset view.

‍

Your NOX balance appears once the swap confirms.

‍

If you do not see it, use the search bar inside Base App and search for NOX again using the same contract address.
