Curation Fee Management

Curators can earn a fee on the restaking rewards generated by the assets deposited in Byzantine Vaults. This section details how curation fees are managed within ERC20 and native ETH vaults created using the ByzVaultParams or NativeByzVaultParams structures.

Key Characteristics of the Curation Fee

• The curator fee is defined at vault creation in the ByzVaultParams.curatorFee field.

• It is expressed as a percentage out of 10,000. For example:

  • curatorFee = 1000 means 10%

  • curatorFee = 2500 means 25%
