In May 2024, a theft occurred on pump.fun, where attackers stole approximately $2 million in SOL and a large volume of meme coins. At the time, the attacker claimed to randomly airdrop these funds to Solana users, earning him the nickname “Robin Hood of the crypto world.”

Jarett Dunn (online alias Stacc), the attacker and former pump.fun employee, was sentenced to six years in prison by a London judge in December of last year.

Two days ago, he leaked a substantial number of Telegram chat logs from his time at pump.fun.

I spent considerable time reviewing these chat logs line by line. After reading through them, I was stunned—because they contained none of the expected malicious behavior I had anticipated, such as pump.fun team manipulating liquidity or siphoning user transaction fees. Nor did they reveal any serious personal moral failings involving founder alon or other team members.

Yet, in his tweets, Jarett Dunn claims to be a whistleblower, framing his disclosure as a “justified explosion” of truth. Some commenters echoed similar confusion, prompting his response:

“These records show I warned them twice that KYC/AML compliance was mandatory before launching live streams on the platform—yet they ignored it. And we all know how things ended up (referring to the unregulated livestream chaos in pump.fun’s early days).”

If this accusation holds some weight, the next one takes a sharp leap:

“An employee said in the group: ‘My friend is already scouting models—once pump.fun goes live with streaming, they’ll bring in explicit content.’”

The corresponding chat log reveals the following: pump.fun co-founder Sapijiju shared a Twitch streamer in the company group, noting another streamer had launched tokens via pump.fun. An employee responded, saying this streamer was a Rugger who had rug-pulled five tokens the previous day.

Then, the same employee mentioned his friend was looking for “models” (to do the same thing). Contextually, this appears to be a joke. However, Jarett Dunn interjected with a suggestion advocating collaboration with streaming platforms—arguing this would avoid KYC obligations and drastically shorten the timeline for launching live features on pump.fun.

The real issue here isn’t the suggestion itself, but rather the team’s apparent indifference toward a known chain of Ruggers, treating it with casual humor. Founder alon, in the record, says he “felt like he’d seen her profile before,” then leaves it at that.

Other logs expose pump.fun’s early “bootstrapped” state—for example, creating contracts under investor pressure (to demonstrate headcount) despite viewing the contract draft as “a complete mess,” while simultaneously seeking legal counsel to draft a new version. For a young project like pump.fun at the time, this hardly qualifies as scandalous.

The most explosive revelation in Jarett Dunn’s disclosed logs may be the exposure of the phone numbers linked to alon and Sapijiju’s Telegram accounts. Given privacy concerns, those screenshots are not included in this article.

So what could possibly drive such animosity? From the logs, I found no clear origin of conflict between Jarett Dunn and pump.fun. Yet he is a talented programmer diagnosed with paranoid schizophrenia at age 20.

Two years ago, when he attacked pump.fun, his mother had just passed away. At that time, he had only been with pump.fun for six weeks.

Four days after the attack, he was arrested at a hotel just 90 meters from pump.fun’s London office—where he had been staying. Following arrest, authorities deemed him unfit for interrogation and transferred him to a hospital for two weeks of psychiatric treatment, having stopped taking medication for months prior.

Two months after pleading guilty, he attempted to withdraw his plea during sentencing—a sudden reversal that caused his legal team to disband.

In September 2023, he tweeted: “I have nowhere to go—I’m preparing to sleep in parks, fighting my own bugs using 5G connectivity.”

Yet in the logs, pump.fun reimbursed his flight from Canada to the UK. Was he happy, hopeful, at peace back then?

Facing such a complex, tormented programmer whose life has been shaped by profound hardship, I can only offer a quiet sigh in response to the fragility of human existence.
