Getting started

1. Connect your wallet

Open Sync World and select Connect wallet. Choose an available wallet and approve the connection. If your wallet uses another network, the app will ask to switch to Robinhood Chain.

Transactions require a small amount of ETH for gas. See Network info for the network details.

2. Create your profile

Choose a unique username using letters, numbers, dots, or underscores. The app checks availability as you type.

You can then:

  • Choose a preset avatar.
  • Upload a PNG, JPEG, or WebP image under 2 MB.
  • Add an optional X handle.

Select Create profile and approve the wallet signature. This signature confirms the profile belongs to your wallet. It does not send a transaction.

After setup, the app takes you to Explore. Buying your own key is optional.

3. Open your key market

When you are ready to open your market:

  1. Open the Profile tab.
  2. Select Buy your own key.
  3. Review the quote and confirm the transaction. The first key costs 0 ETH, but the wallet still charges ETH for gas.

This creates your first key and opens your private room. You receive a 5% subject fee when someone buys or sells your key.

4. Explore profiles

Explore includes:

  • Top users ranked by holder count.
  • 24h gainers based on recent price movement.
  • Recent trades from current activity.
  • Search by username or wallet address.

5. Buy a key

Open a profile and select Buy. The confirmation shows the live quote and the fee breakdown. The total fee is 10%. The profile owner receives 5%, and Sync World receives 5%.

After the transaction confirms, the profile's room becomes available in Chat.
