Pump.fun launched Custom Pairs, a feature that lets users issue tokens paired with tokenized stocks, major crypto assets, metals, and other assets on Solana. Through a partnership with Sunrise, the platform added 20 new asset pairs, including BA, BABA, BULL, COST, DELL, DJT, HIMS, IBM, JNJ, LMT, LULU, MGM, PFE, QUBT, RBLX, RDDT, RIVN, SHOP, SNAP, and UPS. xStocks and Sunrise now support 93 asset pairs, with more planned. Pump.fun said Custom Pairs will use the same bonding curve and PumpSwap protocol fee structure as standard token launches. Half of related revenue will go to the PUMP programmatic buyback and burn smart contract, while issuers can set creator fees from 0.05% to 1% or use a Cashback model that returns fees to traders.
