Documentation for eth_defi.vault.fee.FeeData Python class.

class FeeData

Bases: object

Track vault fee parameters

  • Offer methods to calculate gross/net fees based on the vault fee mode

  • None means fee unknown: protocol not recognized, or fee data not available

How fees are presented:

  • Gross fees are what vaults track internally. They are not exposed to an investor, and only useful for internal profit calculations of the vault. Gross fees have already been deducted when the vault share price is updated.

  • Net fees are deduced at a redemption. A vault investor receives less than the value of their shares back.

  • For comparing the profitability of vaults, you need to reduce the net fees of an investment period from the vault share price.

  • Common vault fee mechanisms implementations are: externalised (net fees, deducted from an investor at a redemption),

    skimming (redirected from profits at the time of trade) and minting (new shares minted to the vault owner at the time of trade).
