Pump.fun exploiter reportedly arrested in London, addresses scandal in X post

Quick Take

  • The person behind the $1.9 exploit of meme coin marketplace Pump.fun has been arrested in London, according to media reports and an X account associated with the exploiter. 
  • In a series of erratic posts, the exploiter threatens the Pump.fun team with further legal action in return and claims to have been released on bail, currently residing in a hospital. 

The former employee that Solana-based memecoin launchpad Pump.fun acknowledged as the person behind the platform's recent $1.9 million exploit has been arrested and released on bail in the United Kingdom, media reports suggest. 

Last Thursday saw the exploiter, who goes by StaccOverflow on X and whose real name is reportedly Jarrett Dunn, use his access to Pump.fun's admin privileges and leverage flash loans in order to siphon nearly $2 million in liquidity from the platform. 

Now Dunn, from a separate X account, has addressed the incident, claiming that he "spent overnight in custody as the pump team alleges I stole 2m of their Ill gotten gains with conspiracy to steal another 80m." Dunn also called for U.K. citizens to file charges against a company he identified as Pump.fun's corporate entity.

In messages with Dunn, another X account reported that Dunn plans to remain in the U.K. before a court-mandated appearance current scheduled for August, having been released on free bail. Dunn appears to be in a hospital for the time being, referencing a "super restricted hospital iPad" as his access point to X.
