Although Dunn claimed that his act was a kind of public denunciation, the justice system did not buy his version.
The developer is considered by some to be the “Robin Hood of cryptocurrencies.”
A former developer of the Pump.fun platform was sentenced this Thursday to 6 years in prison in London, after admitting to having diverted nearly 2 million dollars (USD) in Solana from his employer. The information was confirmed by Wood Green Crown Court.
This is Jarett Dunn, a Canadian citizen who worked for 6 weeks in the memecoin creation ecosystem before diverting funds from Pump.fun last year.
According to the court, Dunn has already spent 308 days in protective custody, of which 154 will count towards his sentence. In addition, he spent around 5 months in preventive detention.
Although Dunn had pleaded guilty to the charges in August 2024.the judicial process had several twists. In October of that year, during a hearing scheduled for his sentencing, the man involved tried withdraw his guilty plea. This caused his legal team to drop the case.
After months of delays in court and while living on bail in London hotels, he breached the conditions of that bail by moving to Liverpool in June 2025. His action led to his arrest and transfer to custody.
From jail, and with a new legal team, Dunn decided in August 2025 to reverse his previous position and reaffirm his initial guilty plea. Thus, he signed a document that ratified his admission of the crimes of fraud due to abuse of position and transfer of criminal property. This tortuous path culminated in this Thursday’s sentence, where the judge imposed two sentences of 6 years each, to be served concurrently.
Dunn sought to be a kind of cryptocurrency vigilante
The case, which occurred in May 2024, caught the attention of the industry for the way Dunn handled the funds. Instead of appropriating them, he distributed the assets among thousands of random addresses and immediately admitted the fact on social networks.
This earned him something of a cult following, with followers dubbing him the “Robin Hood of cryptocurrencies.”
The developer tried to frame the theft as a complaintclaiming that Pump.fun was a malicious platform and that its action was intended to alert the public. However, the judge did not give credibility to this version and proceeded to hand down the sentence.
Jarett Dunn remains in prison in London, awaiting possible deportation to Canada.
Meanwhile, Pump.fun has continued working on its ecosystem. As reported by CriptoNoticias, the platform has already repurchased more than 12.9% of its total supply of PUMP tokens, a program funded with 30% of the commissions generated by memecoin launches on Solana.
