Former Pump.fun developer sentenced to six years in prison for $2 million fraud case

According to Odaily, Canadian citizen Jarett Dunn has been sentenced by a London judge to six years in prison for a $2 million Solana scam. He had previously pleaded guilty to abuse of position fraud and transferring criminal property.

The court stated that this former Pump.fun employee had already been electronically tagged and monitored for 308 days, of which 154 days will be counted towards his sentence. He was also held in custody for about five months, which is typically automatically included in the sentence.

The sentencing comes more than a year after Dunn stole approximately $2 million worth of Solana (SOL) from Pump.fun, a now very popular meme coin platform where he was employed at the time. Dunn did not keep the money for himself but instead distributed the funds to thousands of random addresses. He then immediately admitted to the crime on social media. As a result, the Canadian gained a group of fervent followers, with fans dubbing him the "crypto Robin Hood."

Dunn's road to sentencing was not smooth, with multiple dates set, postponed, and adjourned. This included Dunn's attempt to characterize the attack as whistleblowing, claiming Pump.fun was a malicious website and that he was trying to warn people about it. However, as the sentence was handed down, the judge did not appear to accept this argument.

Pump.fun is a platform that allows anyone to create a crypto token within seconds after filling out a short form. Before the incident, Dunn had worked as a senior developer at Pump.fun for six weeks, during which time the platform, though popular, was still in its early stages. According to Dune data, Pump.fun's cumulative revenue at the time was $43.9 million, a figure that has since soared to $927.2 million.

Dunn's friend Mark Kelly attended the trial and described the verdict as "disheartening." Kelly told Decrypt that prosecutors dismissed the whistleblower claim as "an excuse made after arrest." He added that while he thought Dunn's lawyer was "absolutely terrible," Dunn ultimately made things easy for the prosecution by confessing on social media. "Everyone calm down, this is a robbery... I'm about to change the course of history. Then rot in jail," Dunn wrote on X minutes after the attack. "Am I sane? No. Am I okay? Absolutely not." He then joined an X Spaces, stating he wanted to "kill" Pump.fun "because it's something that needs to be done." He further claimed, "It has inadvertently hurt people for a long time." Kelly added that the judge "fully considered" this during sentencing.

Four days after the attack, Dunn was arrested at a hotel in London, not far from the WeWork where Pump.fun operated and where Dunn was located during the attack. Dunn was immediately deemed unfit for police questioning and spent two weeks in hospital to improve his mental health, having been off medication for months prior.

Subsequently, Dunn pleaded guilty in August 2024, but tried to withdraw his plea at a sentencing hearing two months later. This sudden change led to his legal team resigning.

Afterwards, the Canadian citizen spent months under police supervision searching for a new legal team. He was jailed in July 2025 for breaching bail conditions and pleaded guilty again in August. Since then, he has been awaiting sentencing at HMP Pentonville, communicating with his followers via his X account operated by a so-called "intern."

On Thursday, Dunn was sentenced to two concurrent six-year prison terms for fraud and transferring criminal property.

He has not yet issued a statement through his "intern," but Dunn previously stated that he hoped to be immediately deported back to Canada. However, this has not happened, and Dunn remains in custody in London. (decrypt)
