A hacker just lost nearly $5 million in crypto because of one costly mistake.

A wallet linked to the Binance hack attempted to swap 908,793 $PROM tokens, worth around $5 million, on Uniswap V2.

The problem? The hacker sent the tokens into an almost empty liquidity pool.

The result was shocking: the entire swap returned just 0.0316 $ETH , worth roughly $71.

That’s a potential $5 million in tokens exchanged for barely the price of a dinner.

A costly reminder of how liquidity works in DeFi. A token’s market value means very little when the pool cannot support a large trade.

One transaction. One empty pool. Nearly $5 million in value wiped out.
