**Key Capability**: Real-time AML/CTF screening with < 400ms processing time.

### 2.8 Liquidity Architecture

**Three-Tier Liquidity System**:

1. **GLP (Global Liquidity Pool)**: Multi-source aggregation with 3-tier withdrawal
2. **ID-SLG (Infinite-Dimensional Sovereign Liquidity Grid)**: Infinite liquidity continuum
3. **TRLM (Trans-Reality Liquidity Mesh)**: Cross-reality liquidity routing

**Key Capability**: Automatic, assisted, and crisis intervention liquidity management.
