Summary

Executive Summary This report presents the results of our engagement with StakeWise and Consensys to review v3 Vaults/EthFoxVault implementation for Consensys. The review was conducted over three weeks, from January 29, 2024, to March 1, 2024. A total of 30 person-days were spent. Stakewise V3 is a liquid staking protocol set to be utilized by Consensys as the underlying system for Metamask Staking. This modular system comprises a collection of customizable modules that define the behavior of a staking vault.
