SecuritizeVaultHistoricalReader

Documentation for eth_defi.tokenised_fund.securitize.historical.SecuritizeVaultHistoricalReader Python class.

class SecuritizeVaultHistoricalReader

Bases: eth_defi.vault.base.VaultHistoricalReader

Read Securitize token supply and reviewed NAV/share.

Securitize tokens expose ERC-20 supply but no common fund NAV interface. Fixed-price products use their reviewed adapter estimate; variable-NAV products read a RedStone push feed in the same historical multicall.

Create a historical reader.

Parameters

• vault – Securitize DSToken vault adapter.

• stateful – Whether to attach shared adaptive reader state.
