Binance hacker token swap turns $5M in PROM into just $71 in Ether

A token swap by a wallet linked to the Binance hacker exchanged PROM valued at about $5 million for just $71 in Ether, according to details reported by Lookonchain and shared publicly on November 1, 2026. The wallet sold into a nearly empty Uniswap V2 pool, losing close to the entire reported value of its position.

Key takeaways

• The wallet exchanged 908,793 PROM on Uniswap V2.
• Its payout was only 0.0316 Ether.
• Almost nonexistent pool liquidity produced extreme slippage.

The Binance hacker-linked token swap in numbers

The wallet exchanged 908,793 PROM tokens and received 0.0316 Ether, Lookonchain reported. The blockchain analytics account attributed the wallet to the Binance hacker.

The two dollar figures measure different sides of the transaction. About $5 million was the stated value of the PROM offered for sale; approximately $71 was the value of the Ether actually received. That left a loss of nearly 99.999% against the position’s reported value.

Nearly empty liquidity drove the loss

The Uniswap V2 liquidity pool held almost nothing to exchange against the large PROM sale. That shortage caused extreme slippage and sharply reduced the payout.

Uniswap pools determine token prices from the assets they hold. When liquidity is very thin, a large sale pushes the execution price down sharply—an effect known as slippage. Here, the pool returned only a small amount of Ether despite the much larger stated value of the tokens entering it.

The Binance hacker-linked token swap therefore illustrates a distinction visible in the transaction itself: the reported value of a token position is not the same as the amount a particular pool can pay for it.

Lookonchain linked the sale to wider altcoin dumping

The PROM transaction formed part of a broader effort by the hacker to sell altcoins, the report said. Lookonchain supplied the wallet attribution and trade figures, which a verified Binance account also shared publicly.

The shared figures put the PROM amount at 908,793 tokens and the loss at almost the position’s full reported value.
