Hold a paddle.Press to bid.Last bid standing wins.
Bid3 runs a live auction from physical tags. Every listing, bid and hammer price is written to Arkiv, so anyone can check the result without asking us.
How a round works
- 1
Switch your paddle on
Slide the switch to join the room. The light glows steady once the room has you. Bidding starts when the auctioneer opens the round.
- 2
Press BID to raise
Each press bids the next price, 5% above the last. You can't outbid yourself, and a stale press is refused so you never bid a price you didn't see.
- 3
Hold the lead to the hammer
Every bid restarts the call: going once, going twice, sold. If nobody presses before it ends, the leading paddle wins at that price.
Switching off stops you bidding but doesn't withdraw a bid that's leading. If a paddle's signal drops, only that bidder is blocked while bidding continues. A gateway, bridge or engine outage pauses the room.
On the public record
The room runs fast on our engine. What it decides lands on Arkiv, where any app can read it, even when our server is off.
- The listing
- written by the seller's own wallet, so we can't quietly change it
- The rules
- frozen before the round opens, with a hash anyone can recompute
- Every bid
- one entity per accepted press, in order
- The result
- hammer price, winning paddle and the issuer's wallet
Kept off Arkiv: the live countdown, tag keys and anything personal. Bidders appear only as a paddle alias for one round.
