# Deposit ETH

Use the Deposit panel, save its recovery note, and wait for a confirmed deposit.

A **Single deposit** creates one private balance and one recovery note. Keep the note: you need it to restore that balance later.

> **Warning:**
> 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](/concepts/fixed-denominations.md) only if you want the protocol details.

_Set the amount and note template before saving the recovery note._

## Create one deposit

### Connect your wallet

Use **Connect wallet**. Check that the account and network in the wallet match what Nullark shows.

### Choose Single deposit and amount

In **Deposit**, choose **Single deposit**, then choose one **Selected amount**.

### Choose the Private note template

Under **Private note template**, select **One note** or **Bundle**. Changing the amount or template creates a different recovery note.

### Save recovery note

Under **Save recovery note**, use **Copy** or **Download .txt**. Open the saved copy, then check the acknowledgement.

### Review and submit

Select **Deposit**. Confirm the account, network, and exact ETH amount before approving.

### Wait for Confirmed

Keep the page open until the app shows **Deposit successful** and **Confirmed**. **Activity** shows the public pool while you wait.

## More than one deposit

### [Run a multi-deposit queue](/use/multi-deposit.md)

Multi-deposit sends separate `1 ETH` transactions and saves a separate recovery entry for each one.

## Before you close the page

- Saved recovery note is readable.
- Wallet request matched Nullark and the amount you chose.
- App showed **Deposit successful** and **Confirmed**.

> **Warning:**
> 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](/use/troubleshooting.md).
