A BNB Chain rug pull scams users out of $2 million ($11 million at today's BNB prices). Users ask Binance for help. Binance says it has frozen the funds but then retracts the statement. The funds sat in the address for nearly two years when Binance suddenly took action to freeze the scammer's wallet, which had grown to $10.8 million. Previously, Binance had stated that it could not freeze wallets outside exchange addresses due to BNB Chain's decentralized nature. Users are unhappy and demand Binance to do more. This is the story of the PopcornSwap scam.
On January 28, 2021, decentralized exchange PopcornSwap on Build N Build (BNB) Chain executed an exit scam, stealing over $2 million of liquidity providers’ assets through a little known “preUpgrade” function contained in the exchange’s smart contract. Users held out hope that Binance, creator of BNB Chain, would be able to freeze the scammers’ address. The BNB held in the scammer’s account has grown to over $10 million in value since then as users speculated on whether or not the funds had been frozen.
