Blockchain analytics firm Arkham Intelligence has detected on-chain activity from an address linked to Avi Eisenberg, the infamous exploiter of Mango Finance, sparking speculation about his potential return to the crypto market. According to Arkham, the address 'ponnzishorter.eth' signed an Ethereum transaction on April 24, 2026, recorded in block #24951223, with a fee of approximately 0.000049 ETH ($0.11).
Eisenberg gained notoriety in 2022 after draining approximately $110 million from Mango Finance by exploiting a security vulnerability. He subsequently threatened to attack the Aave protocol but faced a swift downfall when he was liquidated on Curve Finance during an attempted liquidation against another user. Eisenberg was later imprisoned for his illegal activities.
The recent on-chain activity has raised concerns that Eisenberg may be reentering the market, though it remains unconfirmed whether the address is still under his direct control. Market participants and security analysts are closely monitoring the situation for potential further moves.
