To buy MPX, you first need ETH. Think of ETH as the fuel that powers crypto transactions.

ETH · The fuel of crypto
ETH is the most widely used crypto after Bitcoin. You need a small amount to pay for transactions (called "gas fees"). On Base network, fees are less than $0.10.
💡 You only need $10–15 of ETH. A small part covers fees (~$0.10), the rest becomes MPX.
STEP 3 OF 8
What is the Base network?
MPX lives on a network called Base. It's important to understand the difference between networks.

Ultra-cheap fees (<$0.10). MPX lives here. Built by Coinbase.

⬡
BNB (Binance)
Different network. You can't buy MPX with BNB directly.
✗ NOT THIS
◎
SOL (Solana)
Different blockchain entirely. MPX is not on Solana.
💡 The key rule: You need ETH specifically on the Base network. Not Ethereum mainnet, not BNB, not SOL.
STEP 4 OF 8
Buy ETH on Base with your card
Now you'll get ETH on the Base network using your credit or debit card. This is the only step that costs real money.

💡 Coming from Binance? You can buy ETH on Binance and withdraw it directly to your wallet address — select "Base" as the withdrawal network.
