Project Overview

Fund Governance Smart Contract is a multi-signature governance system built on the Cardano blockchain that enables controlled fund management with time-based conditions and committee oversight. This project implements a complete governance system that allows an owner to deposit funds, officials to approve releases, and provides mechanisms for both successful fund releases and safety refunds.

Key Concepts:

• Multi-signature governance: Requires multiple officials to approve transactions
• Time-based conditions: Enforces deadlines for decision-making
• Committee oversight: Designated officials with voting power
• On-chain validation: All rules enforced at the blockchain level
• Secure fund management: Prevents unauthorized access and ensures proper fund distribution

Project Requirements

The project successfully implements all four required endpoints:

✅ 1. Deposit Endpoint

• Function: Initialize the governance contract with funds
• Rules: Only the designated owner can deposit funds
• Validation: Owner signature verification
• Output: Creates initial datum with governance parameters

✅ 2. Approve Endpoint

• Function: Officials approve fund release
• Rules:
  • Only designated officials can approve
  • Each official can approve only once (unique signatures)
  • Must approve before deadline
• Validation: Official signature verification and duplicate check

✅ 3. Release Funds

• Function: Release funds to owner when conditions met
• Rules:
  • Only owner can initiate release
  • Current time must be ≤ deadline
  • Approvals count must be ≥ required approvals
  • Full amount must be sent to owner
• Validation: Time, approval count, and amount verification

✅ 4. Refund Funds

• Function: Refund to owner when conditions not met
• Rules:
  • Only owner can initiate refund
  • Current time must be > deadline
  • Approvals count must be < required approvals
  • Full amount must be sent to owner
• Validation: Time, insufficient approvals, and amount verification
