Former Pump.fun dev is being held in a London prison on remand after breaking his bail conditions

Former Pump.fun senior developer Jarett Dunn is being held in a London prison after violating his bail conditions. The dev was jailed while awaiting a hearing regarding his attack on the Solana memecoin.

The Canadian national drained an estimated $2 million from Pump.fun last year and airdropped the funds to random wallet addresses. He lived in London for eight months, but moved north to Liverpool on a whim in early June. At the time, Dunn said that he didn’t like London and that he preferred Liverpool due to its “emptiness.”

This move violated his bail conditions, which restricted his movement and monitored him through an ankle tag. As a result, Dunn was thrown into Walton Prison in Liverpool and held on remand. He was later moved to HMP Pentonville in London in July.

Guilty or not guilty

At first, Dunn pleaded guilty to fraud by abusing his position and transferring criminal property where he had worked for six weeks. Dunn requested to withdraw his guilty plea during an October hearing scheduled for his sentencing. This resulted in his legal team quitting the case.

Since then, he has been awaiting a hearing to withdraw his guilty plea formally. However, recently, he has been considering pleading guilty again. On an X post, he wrote, “Bail was denied a couple of times and I may just stick with a guilty plea and serve my time and earn a couple of degrees.” 

According to reports, the social media posts were made by his friend Mark Kelly, who has been communicating with Dunn through a series of calls from behind bars. Dunn, or the so-called crypto Robin Hood, has been making communications with those who consider him a hero. 

Before Dunn attacked the platform, Pump.fun was popular, but it had attracted a negative reputation among some observers. This is because it became a hotspot for pump-and-dump schemes and questionable promotional stunts. 

“I just kind of wanted to kill Pump.fun because it’s something to do […] It’s inadvertently hurt people for a long time, and it was just gonna get worse in my opinion […] It was gonna explode in flames […] I just wanted to do it early before they managed to do it themselves and cause a lot more damage,” Dunn said.

At the time of the crime, Dunn had been diagnosed with schizoaffective bipolar disorder, panic disorder, and ADHD, but hadn’t been taking any medication for three months. When he was arrested, it was determined that he was unfit to face an interview due to his mental health. He was hospitalized under Section 136 of the Mental Health Act. Still, the developer could face a minimum of seven years in prison. 

PUMP records ATH in revenue

Dune data shows that Pump coin’s lifetime income has gone up from $43.9 million at the time of the attack to $770 million in July. Pump.fun became the hub of the meme coin craze, giving rise to Moo Deng, Chill Guy, Fartcoin, and many other controversial tokens.

Dunn was arrested just as his old boss was getting ready for a huge initial coin offering worth $600 million. Earlier this week, Pump.fun completed its ICO and debuted its PUMP coin.

Details remain outstanding about exactly when the platform might airdrop the 24% of its supply it set aside for community and ecosystem initiatives. Right now, it is the 68th largest cryptocurrency by market cap.
