# 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

- `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
- SWIFT message generation
- TARGET2 integration
