A deposit creates a private balance and publishes an encrypted recovery record with the deposit. The same wallet can scan and decrypt that record later. A nullark1_... bearer recovery note is a recommended optional fallback, not a deposit requirement.
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

Robinhood Chain publicly shows the sending wallet, exact ETH amount, time, transaction, and encrypted recovery bytes. Note secrets remain encrypted.

​
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.

Create one deposit

1

Connect your wallet

Use Connect wallet. Check the account and network, then approve the private-balance unlock signature only on the official app. Nullark uses this wallet-bound result to protect the encrypted recovery record.
2

Choose an amount

In Deposit, choose one Selected amount.
3

Choose the Private note template

Under Private note template, select One note or Bundle. Changing the amount or template creates a different deposit plan and matching recovery material.
4

Review and submit

Select Deposit. Confirm the account, network, and exact ETH amount before approving.
5

Wait for Confirmed

Keep the page open until the app shows Deposit successful and Confirmed. Activity shows the public pool while you wait.
6

Optionally save recovery note

Open Save recovery note using the Recommended control, then use Copy or Download .txt. This bearer note remains usable when wallet recovery is unavailable. Anyone with it may be able to withdraw the matching balance.

​
Before you close the page

  • If exported, the bearer recovery note is readable from its safe storage location.
  • Wallet request matched Nullark and the amount you chose.
  • 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.
