TheoITokenHistoricalReader

Documentation for eth_defi.tokenised_fund.theo.historical.TheoITokenHistoricalReader Python class.

class TheoITokenHistoricalReader

Bases: eth_defi.vault.base.VaultHistoricalReader

Read thBILL supply without fabricating NAV or TVL.

Theo’s iToken conversion interface returns a basket of assets rather than one scalar price. A price would need reviewed basket valuations, so this reader retains only the verifiable ERC-20 supply observation.

Create a supply-only iToken reader.

Parameters

• vault – Theo iToken adapter.

• stateful – Whether to retain supply-only adaptive reader state.

Methods summary

__init__(vault, stateful)	Create a supply-only iToken reader.
construct_multicalls()	Construct the ERC-20 supply read.
process_result(block_number, timestamp, ...)	Convert a supply read to an explicitly unpriced history row.

__init__(vault, stateful)

Create a supply-only iToken reader.

Parameters

• vault (TheoITokenVault) – Theo iToken adapter.

• stateful (bool) – Whether to retain supply-only adaptive reader state.

construct_multicalls()

Construct the ERC-20 supply read.

Returns

A totalSupply() multicall.

Return type

collections.abc.Iterable[eth_defi.event_reader.multicall_batcher.EncodedCall]

process_result(block_number, timestamp, call_results)

Convert a supply read to an explicitly unpriced history row.

Parameters

• block_number (int) – Sampled block.

• timestamp (datetime.datetime) – Naive UTC timestamp for the sampled block.

• call_results (list[eth_defi.event_reader.multicall_batcher.EncodedCallResult]) – Responses to construct_multicalls().

Returns

Supply-only thBILL observation.

Return type
