A Single deposit creates one private balance and one recovery note. Keep the note: you need it to restore that balance later.
A Nullark recovery note can unlock its private balance. Anyone who gets it may be able to withdraw. Keep it offline, never paste it into another site, and never send it to support.

​
What everyone can see

MegaETH publicly shows the sending wallet, exact ETH amount, time, and transaction.

​
Pick an amount

Choose an amount currently shown under Selected amount. Leave enough ETH in the wallet for gas. If an amount is missing or disabled, do not type or force it manually. Read Why amounts are fixed only if you want the protocol details.

Before you close the page

  • Saved recovery note is readable.

  • App showed Deposit successful and Confirmed.
Never recreate or edit a recovery note. If the app does not show Confirmed, do not deposit again. Keep the page open and use Troubleshooting.
