The 22-year-old behind the memecoin $ZEREBRO, died by suicide on May 4

It was a shocking moment for those watching live and for the broader crypto community. But what's even more puzzling is what happened after.

The 22-year-old developer of the memecoin $ZEREBRO, Jeffy Yu, died by suicide during a livestream on Pump.fun on May 4. It was a shocking moment for those watching live and for the broader crypto community. But what’s even more puzzling is what happened after.

Within hours of his death, activity started showing up on the blockchain from wallets linked to Jeffy. One of those wallets sold over $170,000 worth of $ZEREBRO tokens in a series of transactions.

Another address that created his final token, $LLJEFFY, started receiving USDC, buying back $LLJEFFY, and burning it. This continued for days after his passing.

The timeline is tight. At 5:25 am UTC on May 4, $LLJEFFY launched. Minutes later, at 5:48 am, rumors of Jeffy’s suicide began spreading on X (formerly Twitter). That same morning, multiple wallets tied to him began moving large amounts of tokens, selling ZEREBRO, converting it to USDC, and pushing funds into the wallet that launched LLJEFFY.

That wallet then bought back the token and burned it. Over 90% of the $LLJEFFY supply has now been burned.

Some on-chain observers noticed this pattern and flagged it. One tweet pointed out how the ZEREBRO-selling address sent USDC to HTX, withdrew it, and then funded the LLJEFFY creator wallet, which then bought and burned more of the token. It looked automated. Possibly a bot. But the activity hasn’t stopped.

At first, some doubted the news of Jeffy’s death. The only source confirming it was an obituary posted on Legacy.com, a website that allows paid submissions. The post was later deleted. This raised questions. Was this real? Was it a marketing stunt? Had someone faked a death to launch a token?

But it wasn’t fake. Unfortunately, several confirmations have now come out, and the livestream left no room for doubt.

Just two days before he died, Jeffy had written about a new idea he called “Legacoins.” He believed memecoins should be about legacy — not speculation. He argued that developers should never sell their own tokens, and that after they die, their wallets should remain untouched, making those tokens scarce forever. $LLJEFFY was his first Legacoin.

That’s why what’s happening now is so strange. Even after Jeffy’s death, his wallets are still moving. Tokens are being bought and burned. Either Jeffy coded this automation before he died, or someone close to him is carrying out his final vision. Either way, it’s deeply unsettling — and oddly poetic.

For some, this is a touching tribute. For others, it raises new questions about how crypto handles grief, legacy, and the thin line between honouring someone and turning tragedy into hype.

Jeffy’s final project wasn’t just a coin. It was a message. And for now, that message is still being written — one wallet transfer at a time.
