# Overview

Stable exposes core settlement behavior through **System Modules**, implemented as **precompiled contracts** for gas efficiency and predictable control.

**Key modules:**

* Bank Module
  * Handles USDT transfers, balance accounting, and escrow flows
* Distribution Module
  * Fee distribution and reward logic for network participants
* Staking Module
  * Controls validator participation and staking (coming with mainnet)

**DApps can leverage built-in modules instead of re-implementing token or settlement logic.**
