This could be your ad!

Kiwi News offers ad slots on its site through a smart contract that uses a Harberger-style pricing model, where the ad's price is set by collateral staked in ETH. The article says the site reaches roughly 150 to 400 individuals in the crypto space a day, and the contract is meant to help discover what that audience is worth to advertisers. The owner pays a fee equal to 100% of their collateral per month, and the staked collateral doubles as the price another buyer must pay to acquire the ad. An update dated 2025-04-21 notes that the ad was removed because the website did not have enough impressions to be a good business model at that time.
