Foundation Smart Contract
Overview:
The Foundation Smart Contract is a Solidity-based contract that facilitates the management of a committee with various roles (Research, Technical, FoundationMember) and the rotation of those roles using session keys. It provides a structured way to handle changes in committee member roles and enables role rotation based on specific criteria.
Features:
Getting Started:
Prerequisites:
To interact with the Foundation Smart Contract, you'll need:
Usage:
Contract Initialization:
The contract should be deployed with the following parameters:
researchMembers
: An array of addresses representing Research committee members.technicalMembers
: An array of addresses representing Technical committee members.foundationMembers
: An array of addresses representing Foundation Member committee members.Transferring Roles:
initiateNewChain
function.changeMembersUsingSessionKeys
function, which checks whether a rotation is due based on the rotationThreshold
