#### Fathom Protocol Smart Contract Architecture
The structure comprises distinct modules, each responsible for a set of defined operations.
**Core Components**
1. **Proxy Module**: Interfaces for the core contracts of the protocol.
* **ProxyWallet**: Calls functions within the FathomProxyActions contract for user interactions.
* **ProxyActionsStorage**: Stores the address of the FathomProxyActions contract.
* **ProxyWalletRegistry**: Oversees the creation of proxy wallets owned by users.
2. **Position Module**: Handles the creation and tracking of user positions.
* **PositionManager**: Initiates user positions and maintains a record of them.
3. **Stablecoin Core Module**: Central to the management of the FXD stablecoin's lifecycle.
* **BookKeeper**: Monitors and manages each position's locked collateral and debt share.
* **CollateralPoolConfig**: Manages configurations for collateral pools.
* **StablecoinAdapter**: Oversees the minting and burning functions of the FathomStablecoin contract.
4. **StableSwapModule**: Supports the provision of liquidity and the execution of FXD<->xUSDT 1:1 swaps.
* **StableSwapModuleWrapper**: Integrates and administers the protocol's liquidity pools.
5. **Price Module**: Delivers accurate price information for assets.
* **PriceFeed**: Gathers price data from price source and feeds it into the protocol.
* **PriceOracle**: Transforms raw price from PriceFeed to include a safety margin, using the LTV ratio.
6. **Liquidation Module**: Maintains the protocol's financial health by managing under-collateralized positions.
* **LiquidationEngine**: Carries out the liquidation process according to predefined rules.
* **FixedSpreadLiquidationStrategy**: Directs liquidation activities, ensuring consistency through a fixed spread.
7. **Emergency Module**: Pause or Terminate the protocol.
* **ShowStopper**: Stops and terminates the whole protocol and executes the emergency shutdown process to return collateral
* **AdminControls**: Pauses the protocol at once.
