Ethbid

ETHBid is a discovery market on Arbitrum. Projects bid Paxos USDG to rank on a public leaderboard, and a higher bid gets more homepage exposure and clicks. Ranking runs fully onchain through the ProjectRegistry, RankingRound and BidRouter contracts. A bid costs about $0.02 in gas on Arbitrum, compared with about $0.51 on Ethereum.

Ethbid was already live on ethereum mainnet, so during the buildathon i ported it to arbitrum.

I redeployed all 3 contracts on arbitrum sepolia, switched bids to paxos USDG, and kept ENS names resolving from L1.

Gas per bid dropped from about 50 cents to 2 cents, which means small teams can actually afford to compete for visibility now.

I also fixed a bug where withdrawn bids were showing as "claimed #0", and shipped the arbitrum version live at arb.longbid.lol. next up is arbitrum one mainnet and getting the first real projects on the board.

Bootstrapped, no funding raised yet. solo builder for now, open to grants and talking to investors after mainnet launch on arbitrum one.
