Since debuting earlier this year, Pump.fun has become the de facto launchpad for memecoins on the Solana blockchain. It spawned multibillion-dollar hits including PNUT and WIF. Along the way, it generated over $250 million for its founders, who developed the app in the U.K.
Memecoin traders immediately attempted to capitalize on the ban by creating joke cryptocurrencies that lampooned the news. None of the assets had taken off at press time.
