CHLOM Global DAO — Governance Smart Contract Specification (Phase 4)

Owner: CrownThrive, LLC Date: 2025-08-08 Classification: Internal — DAO Governance Contract Development Guide

1. Purpose & Scope

This document defines the complete technical and functional specification for the governance smart contracts that will power CHLOM’s Global DAO during Phase 4. It ensures developers, auditors, and governance facilitators have a clear, end-to-end reference for contract logic, security measures, interoperability requirements, and deployment standards.

The focus is on:

• Enabling secure, flexible proposal creation and voting.
• Integrating DAO rules with compliance and licensing enforcement.
• Supporting scalable, upgradeable governance models.
• Preparing for seamless Phase 5 transition.

2. Governance Contract Architecture

Modules:

1. Proposal Management Module (PMM)
2. Voting Mechanism Module (VMM)
3. Execution Module (EM)
4. Upgrade & Parameter Control Module (UPM)

3. Data Structures & Storage

• Proposal Struct:

struct Proposal {
  uint256 id;
  address proposer;
  string title;
  string descriptionHash;
  uint256 startBlock;
  uint256 endBlock;
  ProposalState state;
  mapping(address => Vote) votes;
}

• Vote Struct:

enum VoteOption { Yes, No, Abstain }
struct Vote {
  VoteOption choice;
  uint256 weight;
}

• Storage Optimizations:
• IPFS/Arweave for off-chain proposal content.
• On-chain references stored as hashes.

4. Security Considerations

• Reentrancy Guards: All external calls wrapped in nonReentrant modifiers.
• Access Control: Role-based access via OpenZeppelin AccessControl.
• Timelocks: Prevent instant execution of sensitive proposals.
• Failover: Emergency pause function controlled by multisig.
• Auditing: Required external security audits before mainnet deployment.

5. External Integrations

• Compliance API Middleware:
• Called before execution to ensure regulatory and licensing compliance.
• Rejects proposals failing compliance checks.
• Treasury Contracts:
• Trigger fund transfers based on approved proposals.
• Multi-sig required for high-value movements.

6. Developer Guidelines

• Language: Solidity for Ethereum-compatible chains, Rust for Substrate runtime equivalents.
• Testing:
• Unit tests for all public functions.
• Property-based testing for voting mechanics.
• Simulation tests for governance scenarios.
• CI/CD:
• Smart contract linting.
• Automated security scans with Slither & MythX.
• Testnet deployment before staging.

7. Phase 4 → Phase 5 Transition

• In Phase 4: Contracts deployed with partial control retained by core governance council.
• In Phase 5: All admin functions transferred to DAO-controlled multi-sig or on-chain votes.

Summary: This specification ensures the governance smart contracts are robust, secure, compliant, and flexible enough to evolve into a fully decentralized governance system in Phase 5.
