How to Buy ETH on OP Mainnet

1. Select ETH on OP Mainnet

Open thirdweb's bridge and pick:

  • Network: OP Mainnet
  • Token: ETH

2. Enter the Amount

Decide how much you want to buy. You'll see the fiat equivalent right away.

3. Choose How You Want to Pay

You've got options:

  • Pay with crypto — ETH, USDC, etc.
  • Pay with a card — Visa, Mastercard, Apple Pay (via Stripe, Coinbase, or Transak).
  • Use a wallet — Pull funds from any wallet, not just the one connected.

Thanks to Universal Bridge's multi-hop routing, you can use tokens on other chains and still end up with ETH on OP Mainnet.


4. Pay with Card (Optional)

If you go the fiat route:

  • Select your local currency (USD, EUR, etc.)
  • Choose a provider
  • Confirm the fees + timing (usually ~2 minutes)

5. Confirm and Receive ETH

Once the transaction is approved, you'll see ETH in your wallet on the OP Mainnet network — ready to use immediately.
