AssetoVaultHistoricalReader

Documentation for eth_defi.tokenised_fund.asseto.historical.AssetoVaultHistoricalReader Python class.

class AssetoVaultHistoricalReader

Bases: eth_defi.vault.base.VaultHistoricalReader

Read Asseto historical supply and NAV/share.

Asseto’s Pricer contract stores NAV/share in 18 decimal USD units. The token proxy exposes ERC-20 supply but is not an ERC-4626 vault, so the product TVL is calculated as totalSupply() * getLatestPrice().

Create a historical reader.

Parameters

• vault – Asseto tokenised fund adapter.

• stateful – Whether to attach adaptive read state.
