# 8. Transaction Types

### 8.1 Standard Swaps

Best-rate routing across CEX/DEX liquidity. Quotes are computed from integrated venues and executed through the optimal path.

***

### 8.2 Private Swaps

Enhanced privacy via a dual-exchange flow with a randomized Layer-1 relay. Intake and outtake occur at different venues; single-use deposit addresses are used.

    A["Exchange A (Intake)
• Single-use deposit
• AML screening
• Convert to relay asset"]
    R["Randomized L1 Relay
• Relay asset transfer
• Breaks deterministic link"]
    B["Exchange B (Outtake)
• AML screening
• Convert to output
• Payout to recipient"]

    A -- "Relay asset" --> R
    R -- "Relay asset" --> B
```

> **Figure 6.** Private swaps: intake → randomized L1 relay → outtake.

### 8.3 Why the Privacy Relay Works (Mechanics)

* **Record segregation:** intake and outtake maintain separate records (sender vs receiver), preventing a single party from reconstructing the full path.
* **Randomized L1 intermediary:** the relay asset breaks deterministic chain analysis between input and output.
* **Single-use addresses:** ephemeral deposit addresses reduce address reuse heuristics.

### 8.4 DeFi (DEX) Swaps

Direct, non-custodial routing on supported chains and AMMs with explicit slippage controls. Privacy-sensitive users can combine DeFi swaps with private flows before/after the on-chain leg.
