CHLOM Smart Contracts: Architecture and Core Modules

Introduction

The CHLOM ecosystem relies on a cohesive smart contract architecture to manage tokenized licenses, governance, and financial operations. This guide introduces the core components and design patterns used in CHLOM smart contracts, focusing on modularity, security, and upgradability.

Core Modules & Interfaces

  • License Modules: Contracts responsible for minting, transferring, renewing, and revoking tokenized licenses.
  • Registry Interfaces: Standardized interfaces that allow different modules (e.g., TLaaS, LEX, DAL) to query and update license status.
  • Governance Module: Handles proposals, voting, and execution for protocol upgrades and parameter changes.
  • Treasury & Fee Module: Manages funds distribution, royalty routing, and payment splitting between stakeholders.
  • Compliance Hooks: Modular hooks that enforce risk scoring, sanctions checks, and other regulatory requirements.

Token Standards

CHLOM uses a combination of ERC‑20, ERC‑721, and ERC‑1155 standards to represent different types of assets:

  • ERC‑20: Fungible tokens for utility and governance tokens.
  • ERC‑721: Non‑fungible licenses representing individual rights.
  • ERC‑1155: Semi‑fungible assets for bundled rights or multi-license sets.

Access Control Patterns

Security is maintained through role-based access control (RBAC) patterns:

  • Owner/Administrator: Has authority over contract upgrades and emergency functions.
  • Issuer: Can mint and modify licenses.
  • Validator: Participates in governance and dispute resolution.
  • Holder: Owns license tokens and can transfer or renew.

Deployment and Upgradability

CHLOM smart contracts follow an upgradeable proxy pattern so logic can evolve without losing state. Deployment involves:

  1. Deploying implementation contracts (e.g., LicenseLogicV1, TreasuryLogicV1).
  2. Deploying transparent proxy contracts pointing to implementations.
  3. Initialising proxies with constructor parameters via initializer functions.
  4. Upgrading by deploying new implementation versions and updating proxy pointers.
