tokenised_fund.asseto.historical

Documentation for eth_defi.tokenised_fund.asseto.historical Python module.

Historical reader for Asseto tokenised fund products.

Classes

AssetoVaultHistoricalReader

Read Asseto historical supply and NAV/share.

class AssetoVaultHistoricalReader

Bases: eth_defi.vault.base.VaultHistoricalReader

Read Asseto historical supply and NAV/share.

Asseto’s hardcoded Pricer products store NAV/share in base-18 units; other registry products use public daily NAV observations. The token proxy exposes ERC-20 supply but is not an ERC-4626 vault, so TVL is calculated as totalSupply() * NAV/share after any required fiat-to-USD conversion.

Create a historical reader.

Parameters

vault – Asseto tokenised fund adapter.
stateful – Whether to attach adaptive read state.

__init__(vault, stateful)

Create a historical reader.

Parameters

vault (AssetoVault) – Asseto tokenised fund adapter.
stateful (bool) – Whether to attach adaptive read state.

construct_multicalls()

Construct the supply and NAV/share multicalls.

Returns: Calls for ERC-20 supply and Asseto NAV/share.
Return type: collections.abc.Iterable[eth_defi.event_reader.multicall_batcher.EncodedCall]

process_result(block_number, timestamp, call_results)

Convert supply and price call results to a price row.

Parameters

block_number (int) – Block that was read.
timestamp (datetime.datetime) – Naive UTC block timestamp.
call_results (list[eth_defi.event_reader.multicall_batcher.EncodedCallResult]) – Results of calls constructed by construct_multicalls().

Returns

Asseto share price, supply and total assets at the block.

Return type

eth_defi.vault.base.VaultHistoricalRead
