Daily ETH auction rules

Every published project can participate. Three advertising placements do not limit the number of participants.

Each daily lot opens at 00:00 UTC. The opening offer is 0.2 ETH; each later offer must add at least 0.01 ETH. Offers are signed by a wallet and accepted by this server. They are not funded on-chain bids.
Each lot closes at 18:00 UTC. An accepted offer during its last 60 seconds extends the close to 60 seconds after acceptance, capped at 18:30 UTC. The server’s time decides acceptance.
The highest accepted offer wins that placement for the following UTC day, 00:00–24:00. Each lot is paid separately. A wallet or project already leading a lot cannot raise its own offer.
Only the winner sends ETH. Payment must be mined on Ethereum mainnet within 2 hours of the final close. The receiving wallet is 0x0CA30b37597BE59A13327a4E247f992a8ccC73F4. Network fees are additional. There is no automatic refund.
A winner who does not pay on time forfeits that placement. Other participants owe nothing. There is no automatic charge or runner-up charge. The unfilled inventory is not represented as sold.
Verification checks the winning wallet, destination, amount, successful transaction, time window, canonical block and Ethereum finality. A pending transfer does not activate advertising. One transfer cannot buy multiple lots.
Paid winners receive labeled Sponsored placements. Publication and ordinary directory inclusion are free. No reach, clicks or financial return is guaranteed.
The looping gavel is ambient animation. It cannot accept offers, close a lot, confirm a transaction or declare a winner.

The older USDC demo remains available separately with simulated money and its own test clock.
