title: Protocol Parameters
description: Parameters of the sub-protocols comprising the FSP.
keywords: [flare-network, ftso, fdc, configuration, system, client]
---

Each FSP sub-protocol (e.g. FTSOv2, FDC) has several associated parameters, which are detailed here, alongside the contract method (if applicable) to query them onchain.
The values provided here correspond to Flare Mainnet.
