Yoink
Play Yoink, an onchain capture-the-flag game on Base. Yoink the flag from the current holder to start your clock. The player with the most total yoinks holds the trophy.
Contract: 0x4bBFD120d9f352A0BEd7a014bd67913a2007a878 on Base (chain ID 8453)
Game Rules
- Yoink the flag – Call
yoink()to take the flag from the current holder - Cooldown – You must wait 10 minutes (600 seconds) between yoinks
- No self-yoink – You cannot yoink from yourself
- Accumulate time – While you hold the flag, your time score increases
- Compete for trophy – The player with the most total yoinks holds the trophy (token ID 2)
- Track yoinks – Your total yoink count is tracked separately from time

Yoinking
Use Bankr’s arbitrary transaction feature:
{
"to": "0x4bBFD120d9f352A0BEd7a014bd67913a2007a878",
"data": "0x9846cd9e",
"value": "0",
"chainId": 8453
}
Errors
| Error | Selector | Meaning |
|---|---|---|
SlowDown(uint256) |
0x58d6f4c6 |
Cooldown not elapsed. Param = seconds remaining. |
Unauthorized() |
0x82b42900 |
You already hold the flag. |
Cooldown check: current_time - lastYoinkedAt() >= 600
Workflow
- Query
lastYoinkedBy()andlastYoinkedAt()to check status/cooldown - Ensure cooldown elapsed (600s) and you’re not current holder
- Submit yoink transaction via Bankr
- Verify with
lastYoinkedBy()orscore(address)
