# MeLong

> Only the ripe ones. Crypto farms we test ourselves.

MeLong is a curated catalog of crypto farms (perp DEXs, prediction markets, crypto cards and tools). Labels: Ripe means we would start today; Ripening means we track it and check the facts but it is below our bar for now; Rotten means skip it. Facts come only from each project's official pages, listed as sources on every project page. Nothing here is financial advice.
