Pump Science posted on the X platform that the token economics design has been completed, including: 5% of the token supply issued in the future will be allocated to previous token holders (at the time of migration); more PS tokens (RIF, URO) will be held now, and new tokens will be available later; as long as new products are launched, this situation will continue (forever). In addition, Pump Science said that the BIO Protocol will airdrop BIOs to holders of UROs and RIFs, pending governance approval to connect BIOs to Solana. More airdrops are under consideration.
