Keep3r Network
Summary
Keep3r Network (KP3R) is a decentralized keeper-job matching protocol launched in October 2020 by Andre Cronje, the creator of Yearn Finance. The protocol has experienced multiple security incidents including a $211k exploit in June 2023, a latent two-year-old vulnerability in its GaugeProxyV2 contract discovered in September 2022, and its oracle was implicated in the $15.6M Inverse Finance hack of April 2022. ZachXBT has flagged the protocol in the context of broader DeFi security concerns, and the project has been surrounded by scam forks, impersonator accounts, and fraudulent staking services operated by unaffiliated parties.
