Pools Backend Overview
Introduction
The Pools Backend includes a full set of APIs and SDK modules to interact with Defactor’s lending infrastructure. These tools enable developers to integrate borrowing, lending, collateral management, and liquidation flows into their applications with ease.
This backend layer supports both ERC-20 Collateral Pools and Counterparty Pools, offering flexibility for open and permissioned lending models.
API Access
The Pools APIs provide programmatic access to lending pool data, loan management functions, and real-time system states.
Use APIs to:
- Query pool and loan information
- Trigger actions like borrowing or repaying
- Monitor status updates and metrics
- Automate backend processes and alerts

These APIs are suitable for teams building custom interfaces, automations, or analytics solutions on top of Pools.
SDK Modules
Defactor’s SDKs are optimized for TypeScript/JavaScript environments and provide utility modules to simplify smart contract interaction, transaction formatting, and wallet integration.
Use SDKs to:
- Integrate on-chain lending logic into dApps
- Estimate gas and prepare transactions
- Wrap and abstract smart contracts into simple functions
Available modules:
- Collateral Pool SDK: Manage ERC-20 token collateralization, borrowing, and repayment.
- Counterparty Pool SDK: Handle permissioned lending flows, lender matching, and custom loan terms.
SDKs are ideal for developers looking to integrate directly into web apps and smart contract frontends.
