Solana-based memecoin launchpad Pump.fun has barred access to U.K. users, citing compliance with "laws and regulations." The move follows a warning from the U.K. Financial Conduct Authority (FCA) earlier this week, which accused the platform of operating without proper authorization.

Known for spawning viral tokens like PNUT and WIF, Pump.fun has become the premier memecoin factory on Solana, generating over $250 million for its U.K.-based founders since launching earlier this year.

The sudden geoblocking has sparked humor among the crypto community, with traders creating parody tokens mocking the situation. However, none have gained significant traction so far.

Pump.fun's founders declined to comment on the regulatory fallout but confirmed the platform's blockade for U.K. traders. As regulators worldwide increase scrutiny on crypto platforms, Pump.fun's response highlights the growing challenges for projects operating in legally uncertain environments.
