Swaprum founders exploited a backdoor add() function in their smart contract to steal approximately $3 million in deposited liquidity pool tokens from users. The stolen funds were laundered through Tornado Cash.

The Arbitrum ecological Swaprum project has a Rug Pull, the price of SAPR has dropped by 100%, Swaprum has deleted the social account, and the scammer bridged 1628 ETH (about 2.94 million US dollars) to Ethereum and transferred it to Tornado Cash.
