Swaprum (SAPR)
An Arbitrum DEX (token SAPR) whose deployer rug-pulled ~$3M in May 2023 by using proxy upgradeability to swap the audited staking contract for a malicious one. Funds were laundered via Tornado Cash. CertiK had audited it weeks earlier and later flagged it an 'exit scam'.
Also known as: Swaprum, SAPR
Summary
Swaprum was an Arbitrum-based decentralized exchange with the token SAPR. On May 18, 2023, its deployer rug-pulled about $3 million by using proxy upgradeability to replace the audited staking ("MasterChef") contract with a malicious version that drained staked LP tokens and minted SAPR. [1][2]
Aftermath
The funds (~1,628 ETH) were bridged to Ethereum and laundered through the Tornado Cash mixer, and Swaprum deleted its social accounts. CertiK had audited the protocol on May 5, 2023, flagging major centralization and upgradeability risks; it later flagged Swaprum as an "exit scam." [2][3]
