In June 2021, a co-founder using the pseudonym 'Kairos' exploited a critical timelock bypass vulnerability in the protocol's vesting contracts — a bug that had been disclosed to the team two months prior — draining approximately $128,000 from liquidity providers and sending 100 ETH through Tornado Cash. The protocol subsequently relaunched as SharedDeposit v2 under remaining team members, though the SGT governance token never recovered.","timeline":[{"date":"2021-01-01","event":"SharedStake founded by pseudonymous co-founders Kairos, Chimera, and Ice Bear as an Ethereum 2.0 staking protocol.","source":""},{"date":"2021-04-26","event":"Whitehat researcher Lucash-dev reports critical timelock bypass vulnerability in SmartTimelock.sol to Immunefi.","source":""},{"date":"2021-04-29","event":"SharedStake team confirms the bug and pays Lucash-dev a $5,000 bug bounty.","source":""},{"date":"2021-05-20","event":"SharedStake requests a fix from Immunefi for the disclosed vulnerability.","source":""},{"date":"2021-06-16","event":"Fix delivered privately to SharedStake.
