Pump.fun is shaking up the Solana memecoin scene with its new lending platform, Pump.Fi, allowing users to borrow crypto to buy memecoins and NFTs. Borrowers pay a third upfront and the rest over 60 days, with a marketplace for lenders to buy debt. Despite no credit checks, Pump.fun is optimistic about boosting liquidity in the memecoin market, which has recently stabilized. Facing competition from Raydium and others, Pump.fun launched PumpSwap, a DEX capturing over 10% of Solana's trading volume, even surpassing Raydium in 24-hour fees.
