Fungible Token Raffle is not supported now. Geeft is a tool for users to send presents with NFTs or token to others with transaction memo by wrapping NFTs and tokens into a Geeft NFT. So, if you really want a Fungible Token Raffle, you can use Geeft to wrap your FT, then use Geeft NFTs to start an NFT Raffle.
