SKILL.md

CMTAT (CMTA Token) is a security token framework for tokenizing real-world financial assets on EVM-compatible blockchains. It's developed by the Capital Markets and Technology Association (CMTA).

Key Modules

Category Modules Purpose
Core ERC20Base, Mint, Burn, Pause, Enforcement, Validation Basic token operations
Extensions Snapshot, Document, ExtraInformation Dividends, legal docs, metadata
Options Debt, ERC2771, ERC1363, CrossChain, Allowlist, ERC7551 Bonds, gasless tx, multi-chain, KYC
Security AccessControl RBAC with roles (MINTER, BURNER, PAUSER, ENFORCER)

Deployment Variants

  • Standalone - Immutable, no proxy
  • Upgradeable - Transparent/Beacon/UUPS proxy patterns
  • Light - Minimal for stablecoins
  • Allowlist - Whitelist-based transfers (KYC)
  • Debt - Bond-specific fields (maturity, coupon)
  • DebtEngine - Debt with external engine
  • ERC-7551 - German eWpG compliance
  • ERC-1363 - transferAndCall support

Architecture Highlights

  1. Modular composition - Mix-and-match features via inheritance
  2. Engine pattern - External contracts for complex logic (RuleEngine, SnapshotEngine, DocumentEngine, DebtEngine)
  3. ERC-7201 storage - Namespaced storage for safe upgrades
  4. Role-based access control - Granular permissions (not single owner)
  5. 10+ standard compliance - ERC-20, ERC-3643, ERC-7551, ERC-2771, ERC-7802, etc.

Contract Inheritance Hierarchy

CMTATBaseCore (0) - Basic ERC20 + Mint + Burn + Validation + Access Control
    ↓
CMTATBaseAccessControl (1) - RBAC roles management
    ↓
CMTATBaseRuleEngine/Allowlist (2) - Transfer validation rules
    ↓
CMTATBaseERC1404 (3) - ERC-1404 compliance (restrictedTransfer)
    ↓
CMTATBaseERC20CrossChain (4) - CCIP & ERC-7802 support
    ↓
CMTATBaseERC2771 (5) - Gasless meta-transactions
    ↓
CMTATBaseERC1363/ERC7551 (6) - Additional standards

Key Roles (Access Control)

  • DEFAULTADMINROLE - Admin access (can grant/revoke roles)
  • MINTER_ROLE - Can mint tokens
  • BURNER_ROLE - Can burn tokens
  • PAUSER_ROLE - Can pause/unpause contract
  • ENFORCER_ROLE - Can freeze/unfreeze addresses
