Former Pump.fun Senior Developer Sentenced to Six Years for $2 Million Solana Fraud
Jarett Dunn, a Canadian former senior developer at Pump.fun, was sentenced to six years in prison at Wood Green Crown Court in London for siphoning about $2 million in Solana from the crypto token creation platform. Dunn pleaded guilty to fraud by abuse of position and transfer of criminal property.
Pump.fun, a platform that enables rapid cryptocurrency token creation, reportedly had a lifetime revenue of $43.9 million at the time of the incident, according to Dune data, with later figures cited as $927.2 million. Dunn worked at Pump.fun for six weeks while the platform was in its infancy.
During the fraud, Dunn distributed the stolen funds to thousands of random addresses rather than keeping them, and announced the crime on social media. He was arrested four days after the attack at a London hotel near a WeWork used by Pump.fun. Following his arrest, Dunn was hospitalized for two weeks for mental health reasons and initially deemed unfit for police interview. Afterward, he was imprisoned at HMP Pentonville. An intern managed his social media account to keep followers updated during this period.
The legal proceedings included Dunn pleading guilty in August 2024, an attempt to withdraw the plea two months later, a bail breach in July 2025, followed by a renewed guilty plea in August 2025. The sentencing followed subsequently. The judge rejected Dunn's attempt to frame himself as a whistleblower, with prosecutors dismissing his post-arrest social-media narrative as spin and not credible.
Dunn had already spent 308 days on tag, with 154 of those counted toward his sentence, and about five months in remand, which also counted toward his total prison term.
