Be early.
Stay original.

Vamping — relaunching another coin's identity to drain its momentum — is the number one killer in the trenches. Every vamp splits liquidity, attention and trust across interchangeable copies until the narrative collapses and every holder loses. based.fun settles provenance at birth: each coin commits its CA and description into its metadata before it exists. The original is provable. Everything else is a copy.

Why vamps die here

Vamps are the #1 problem in the trenches

Every running narrative attracts parasitic relaunches of its own identity — dressed up however the moment demands. Each one splits liquidity, attention and trust across interchangeable copies, and the endless PvP that follows collapses the narrative itself. Holders lose across the board, and newcomers leave the space disheartened. Nobody wins a vamp war.

Based before it exists = unvampable

BASED.FUN generates your coin's CA first, seals it with your description into the metadata on IPFS, and only then creates the coin pointing at it. The CA is stamped on the image itself at 20% transparency — a vamp who steals the image advertises the original. And a ticker launched here can never be launched here again: no relaunches, no "v2", no vamp wearing your ticker.
