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.","timeline":[{"date":"2023-05-01","event":"CertiK begins smart contract audit of Swaprum at the team's request.","source":""},{"date":"2023-05-05","event":"CertiK publishes its audit of Swaprum, flagging 4 major findings related to centralization/privilege.
