Zerebro Founder Commits Suicide On Camera Before On-Chain Sleuths Debunk It: What Is LLJEFFY Crypto

After Jeffy Yu, the founder of AI agent token, ZEREBRO, seemingly died by suicide, a legacy meme coin, LLJEFFY crypto, surged more than 2000% before crashing back down.

Yesterday (May 6), a video was posted to X allegedly showing Jeffy Yu, 22, smoking a cigarette before pulling the trigger and committing suicide. However, on-chain analytics have since shown activity in wallets tied to the ZEREBRO founder, and a posthumous letter from the developer strongly suggests that Yu staged his suicide.

The Plot Thickens In The Jeffy Yu Suicide Drama

The crypto community was in a state of shock and mourning yesterday when the San Francisco Chronicle posted an obituary online for Jeffy Yu. The founder of crypto AI agent ZEREBRO was reported to have died by suicide.

However, the obituary was later removed due to a lack of evidence that Yu had actually passed. provided to local media. The local coroner’s office reportedly claimed that nobody with the founder’s surname had recently passed in the area.

When someone submits an obituary via the San Francisco Chronicle’s online form they are required to pay a fee of at least $299 and provide confirmation of death via the funeral home, crematorium, or a death certificate.

After filing the form, the obituary is automatically uploaded to Legacy.com. Since no confirmation had been given on Yu’s death, the obituary was removed.

Yesterday (May 6), video began circulating on X, showing Jeffy smoking a cigarette before seemingly shooting himself in the head with a gun. From the get-go, there were sceptics in the comments, noting that a lack of gore and the camera going blurry could mean it was staged.

Posthumous Blog Post From ZEREBRO Founder Announces The Launch Of His ‘Legacoin’: A Short Timeline Of LLJEFFY Crypto

(GECKO TERMINAL)

In a scheduled blog post following his death, Yu said; “If you’re reading this, it’s because my 72 hour deadman’s switch triggered so I’m not here, at least physically..This is a legacoin, my final art piece. $LLJEFFY”

In his supposedly posthumous Sunday blog post, Yu announced the inception of the “Legacoin,” a term referencing legacy meme coins that are dedicated to someone who has passed. This post was signed “LLJEFFY,” with many deducing that the ‘LL’ stands for Long Live (Jeffy).

According to Gecko Terminal, the Pump.fun launched Solana token LLJEFFY crypto skyrocketed more than 2,100%, reaching a market cap of around $104.8 million. LLJEFFY crypto has since tanked, falling over 90% from its near $105m market cap to just $14.7m.

The full blog post goes deep into Jeffys struggles with how trading can ruin art, why he hates money, and explains that internet fame led to the downfall of his personal life.

“As soon as I got a little rich and a little famous online, everything meaningful fell apart, friends, family, romantic relationships, co-founders,” the post says. “Nothing was simple anymore, everyone was ulterior.”

Yu co-founded the ZEREBRO project, alongside Tint Blorm. It is an AI agent that gained notoriety due to its emo trap rap career and dry humor on social media.

ZEREBRO was a huge success early on, peaking at a $784 million market cap in January 2025. But its price has since collapsed 95% to $36 million as the AI crypto sector has since lost much of its early hype.
