# Fees and Commissions

Fees and commissions in Covenant system are transparent, public and deterministic as are publicly stated on-chain in smart contracts. Covenant commission rates are publicly DAO-managed. 

System fees and commissions can be divided onto two parts:

1. **Gas fees:** Bitcoin, Ethereum and other networks take fees for transaction processing and executing operations. These fees rate depend on the networks and are roughly calculated before tx execution.
2. **Covenant system commissions:** Covenant system charges commissions for its operations. These commissions are used to reward nodes (and users) that do the useful work - participate in state validation securing and cross-chain messages verification, to provide Yield program and to ensure the Covenant system development and growth.
