Summary

Swaprum was an Arbitrum-based decentralized exchange (DEX) that launched in early 2023 and operated briefly before its anonymous development team executed a deliberate exit scam on May 18, 2023. The team exploited a backdoor function embedded in an upgraded smart contract to drain approximately 1,628 ETH (roughly $3 million) from user liquidity pools, then laundered the proceeds through Tornado Cash and deleted all official communication channels. No funds have been recovered and no arrests have been publicly reported.
