Usage

This service is designed to automate the process of monitoring of borrowers positions and initiating liquidations in the Soroban ecosystem. Here's an overview of how it works:

• The service periodically retrieves borrower positions.
• Borrowers with negative or zero NPV are identified for potential liquidation.
• The service checks the liquidator's balances.
• If the liquidator has sufficient balances, it initiates the liquidation process for the borrower.
• The service handles liquidation errors and updates the database with borrowers accordingly.

POOL_ID - Slender pool address
POOL_ASSETS - comma separated list of pool asset addresses
XLM_NATIVE - address of XLM contract
SOROBAN_URL - Sorban RPC URL
HORIZON_URL - Horizon RPC URL
NETWORK_PASSPHRASE - Soroban passphrase
