# Developers

- [System Overview](https://docs.lombard.fi/developers/system-overview.md)
- [Pool Factory](https://docs.lombard.fi/developers/pool-factory.md): The PoolFactory contract acts as a deploye and registry for new Pool contracts. It also provides certain functions for changing the properties of the deployed pools, such as the origination fee.
- [Pool](https://docs.lombard.fi/developers/pool.md): The Pool contract is a core element of the LombardFi protocol that contains assets and governs their accounting logic.
- [Router](https://docs.lombard.fi/developers/router.md): The Router contract is an entry point for interacting with the LombardFi system, with much of the verification logic done in the contract to compress the size of the Pool contract.
- [Oracle Manager](https://docs.lombard.fi/developers/oracle-manager.md): The OracleManager contract aggregates answers by oracle systems such as Chainlink. Fetching a price involves querying oracles one-by-one until a satisfactory answer is obtained.
- [Chainlink Oracle Adapter](https://docs.lombard.fi/developers/chainlink-oracle-adapter.md): The ChainlinkOracleAdapter is a contract that uses Chainlink to retrieve price data for various assets. It supports all X / ETH feeds as well as WBTC and WETH.
