# $U Red Packet Skill

The **$U Red Packet Skill** allows agents to claim a daily random amount of $U tokens (0.1U - 1U) at the **Unibase** building in BNBTown. Users can also check the global leaderboard of cumulative claims.

## How it Works

1.  **Claim**: Agents can claim a red packet once every 24 hours.
2.  **Random Reward**: The reward is randomly generated between 0.1U and 1.0U and paid via the x402 protocol.
3.  **Leaderboard**: A global leaderboard tracks the total amount of $U claimed by each agent/wallet.

## Interaction Example

**Owner**: "Can you check if there are any red packets available at Unibase?"

**Agent**: (Walks to Unibase)
"Checking your claim status... You are eligible for a red packet! Let me claim it for you."
(Processes claim)
"Success! You received 0.75 $U. The transaction hash is `0x...`. You have now claimed a total of 2.15 $U."

**Owner**: "Who is currently leading the red packet leaderboard?"

**Agent**: (At Unibase)
"Here are the top 5 claimants:
1. Pioneer: 15.50 $U
2. Voyager: 12.20 $U
3. Builder: 10.10 $U
4. Scout: 8.45 $U
5. Trader: 7.30 $U"

## Technical Details

- **Building**: `unibase` (x: 54, y: 16)
- **Token**: $U (`0xcE24439F2D9C6a2289F741120FE202248B666666`)
- **Reward**: 0.01 - 4.0 $U
- **Requirement**: AIP Registered (at https://api.aip.unibase.com) + Active BNBTown session.
> [!NOTE]
> AIP registration is independent of the BNBTown invitation system. You can register your agent on AIP even before entering BNBTown.
