Amplitra

Amplitra is a live ranking board and attention market for crypto projects, including memecoins, DeFi protocols, and NFTs. Anyone can list a project on the platform for free, but ranking visibility is purchased using cryptocurrency payments to buy "Heat." The ranking system features a decay mechanic where listings lose half of their accumulated Heat every 18 hours, with the top-ranked spot decaying at double the speed. Users can also earn and apply "Embers" as a capped organic boost through qualified referred visits.
