Fund via RabbitHole
Buy ETH directly into your TopStrike wallet using a centralised exchange.
RabbitHole is the official onramp for MegaETH. It offers two ways to get ETH into your TopStrike wallet:
Fund
Buy ETH directly using a centralised exchange account (e.g. Coinbase, Binance) or card — no existing wallet needed.
Bridge
Transfer ETH from an existing self-custody wallet on another chain (e.g. Ethereum Mainnet) to your TopStrike wallet on MegaETH.
This guide covers the Fund option — ideal if you don't hold ETH in a personal wallet and want to buy directly from an exchange into your TopStrike account.
What You'll Need
A verified account on a supported exchange (Coinbase or Binance)
Funds available on that exchange (USD, USDC, or other supported currencies)
Your TopStrike wallet address
Step 1: Choose What to Buy
Open RabbitHole Fund. The screen defaults to BUY USDM. Tap the token selector at the top and change it to ETH on MegaETH.
Step 2: Choose Your Exchange
Under Deposit with Exchange, select your preferred exchange:
Coinbase
Binance
Crypto.com (coming soon)
Additional options such as Deposit with Card and Deposit with Wallet are also available on this screen.
Step 3: Choose What to Pay With
After selecting your exchange (e.g. Coinbase), choose your payment currency:
USD — pay directly from your USD balance
USDC — pay using USDC held on the exchange
Make sure you have sufficient funds in your chosen currency on the exchange before proceeding.
Step 4: Enter the Amount
Enter the amount you wish to deposit. You can type a custom amount or use the quick-select buttons (50, 100, 200).
RabbitHole will fetch a live quote for the conversion. Click Checkout to proceed.
Step 5: Review & Update Delivery Address
On the Review & Pay screen, change the delivery address to your TopStrike wallet:
Open the TopStrike App and tap the menu icon in the top right corner.
Select Deposit from the account menu.
Tap to copy your TopStrike wallet address.
Back in RabbitHole, paste the address into the delivery address field.
Review the transaction details and click Pay.
Step 6: Complete Your Order
You will be shown a QR code to complete your order. You can either:
Scan the QR code on your phone to open your exchange app and confirm payment, or
Continue on your current device to open Coinbase/Binance directly and complete the order
Once the payment is confirmed, your ETH will be delivered to your TopStrike wallet and you're ready to trade.
Tip: Always double-check your delivery address before hitting Pay. Funds sent to the wrong address cannot be recovered.
