defiQUG 2b52cc6e32 refactor(archive): move historical contracts and adapters to archive directory 
- Archived multiple non-EVM adapters (Algorand, Hedera, Tron, TON, Cosmos, Solana) and compliance contracts (IndyVerifier) to `archive/solidity/contracts/`.
- Updated documentation to reflect the historical status of archived components.
- Adjusted `foundry.toml` and `README.md` for clarity on historical dependencies and configurations.
- Enhanced Makefile and package.json scripts for improved contract testing and building processes.
- Removed obsolete contracts (AlltraCustomBridge, CommodityCCIPBridge, ISO4217WCCIPBridge, VaultBridgeAdapter) from the main directory.
- Updated implementation reports to indicate archived status for various components.

Tokenization Implementation Complete

Summary

The tokenization system for central bank/IFI settlements has been successfully implemented with full integration across:

  • ✅ Hyperledger Fabric: Chaincode for tokenized assets and reserve management
  • ✅ Hyperledger Besu: ERC-20 token contracts (TokenizedEUR, TokenRegistry)
  • ✅ Hyperledger FireFly: Workflow orchestration and settlement file generation
  • ✅ Hyperledger Cacti: Cross-network bridges (Fabric-Besu, Banking)
  • ✅ Hyperledger Indy: Institutional identity and credential management
  • ✅ SolaceNet: Capability platform integration with routes and policy enforcement
  • ✅ Sub-Volume A (GAS): Atomic settlement integration
  • ✅ Sub-Volume B (GRU): Monetary system integration with XAU triangulation
  • ✅ Sub-Volume C (Metaverse): Virtual asset representation
  • ✅ Microservices: ISO Currency, Liquidity Engine, Market Reporting, Bridge Reserve

API Routes Registered

Tokenization routes have been registered in the API gateway:

  • POST /api/v1/solacenet/tokenization/mint - Mint tokenized asset
  • POST /api/v1/solacenet/tokenization/transfer - Transfer tokenized asset
  • POST /api/v1/solacenet/tokenization/redeem - Redeem tokenized asset
  • GET /api/v1/solacenet/tokenization/status/:requestId - Get status
  • GET /api/v1/solacenet/tokenization/token/:tokenId - Get token details

Key Features Implemented

1. Tokenization Workflow

  • Reserve verification
  • Fabric minting with SolaceNet capability checks
  • Besu ERC-20 minting via Cacti bridge
  • Settlement file generation (blockchain + banking data)
  • Regulatory reporting

2. Reserve Management

  • 1:1 backing enforcement
  • Reserve verification
  • Reserve attestation
  • Multi-attestor quorum support

3. SolaceNet Integration

  • Capability-based access control
  • Policy enforcement
  • Entitlement checks
  • Runtime capability toggling

4. Sub-Volume Integration

  • GAS: Atomic settlement for tokenized assets
  • GRU: Tokenized asset valuation via XAU triangulation
  • Metaverse: Virtual asset representation and cross-reality transfers

5. Microservices Integration

  • ISO Currency: Tokenized asset currency mapping
  • Liquidity Engine: Tokenized asset liquidity management
  • Market Reporting: Tokenized asset reporting and reserve attestation
  • Bridge Reserve: Tokenized asset reserves for bridging

6. Identity & Compliance

  • Indy DID issuance for institutions
  • Verifiable Credentials (KYC, AML, Regulatory Approval)
  • Tier-based access control
  • Policy-based operation checks

7. Banking Integration
