- Commodities
- Tokenized securities

All in a **single synchronized settlement cycle**.

## Core Characteristics

- Settlement < 100 milliseconds
- Multi-ledger synchronization
- Commodity-backed clearing
- Collateralized RTGS via MACE engine

## Queue Management

### Priority Tiers

- **Tier 1:** Sovereign & systemic transactions
- **Tier 2:** Interbank transactions
- **Tier 3:** Retail CBDC traffic during peak hours

### Queue Algorithm

```
priority = systemic_value + fx_cost_penalty + liquidity_weight + SRI_adjustment
```

**Service**: `mrtgs-queue-manager.service.ts`

**API Endpoints**:
- `POST /api/v1/m-rtgs/queue/add` - Add payment to queue
- `GET /api/v1/m-rtgs/queue/next` - Get next payment from queue

## Settlement Processing

**Service**: `mrtgs-settlement.service.ts`

**API Endpoint**: `POST /api/v1/m-rtgs/settle`

Settlement includes:
- Multi-ledger synchronization
- Performance monitoring (< 100ms target)
- Status tracking

## Real-Time Risk Controls

M-RTGS monitors:
- Transaction velocity
- Liquidity congestion
- FX slip
- Commodity price shocks
- CBDC abnormal routing patterns

**Service**: `mrtgs-risk-monitor.service.ts`

**API Endpoint**: `POST /api/v1/m-rtgs/risk/monitor`

## MACE Integration

Collateralized RTGS via MACE engine for risk management.

**Service**: `mrtgs-mace-integration.service.ts`

## Database Models

- `MrtgsQueue` - Queue entries with priority scores
- `MrtgsSettlement` - Settlement records with multi-asset support
- `MrtgsRiskAlert` - Risk monitoring alerts

## Integration Points
