Documentation for eth_defi.erc_4626.vault_protocol.plutus.vault.PlutusHistoricalReader Python class.

class PlutusHistoricalReader

Bases: eth_defi.erc_4626.vault.ERC4626HistoricalReader

Read Plutus vault core data + deposit/redemption state via maxDeposit/maxRedeem.

  • Plutus vaults are manually opened/closed

  • Uses ERC-4626 maxDeposit(address(0)) and maxRedeem(address(0)) to determine if deposits/redemptions are open

  • Trading state is not tracked (always None)

Methods summary

__init__(vault, stateful)

construct_core_erc_4626_multicall()

Polling endpoints defined in ERC-4626 spec.

construct_multicalls()

Get the onchain calls that are needed to read the share price.

dictify_multicall_results(block_number, ...)

Convert batch of multicalls made for this vault to more digestible dict.

process_core_erc_4626_result(call_by_name)

Decode common ERC-4626 calls.

process_result(block_number, timestamp, ...)

Process the result of mult
construct_multicalls()

Get the onchain calls that are needed to read the share price.

Return type

Iterable[eth_defi.event_reader.multicall_batcher.EncodedCall]

process_result(block_number, timestamp, call_results)

Process the result of mult

  • Calls are created in construct_multicalls()

  • This method combines result of this calls to a easy to manage historical record VaultHistoricalRead

Return type

Iterable[eth_defi.event_reader.multicall_batcher.EncodedCall]

dictify_multicall_results(block_number, call_results, allow_failure=True)

Convert batch of multicalls made for this vault to more digestible dict.

  • Assert that all multicalls succeed

Returns

Dictionary where each multicall is keyed by its EncodedCall.extra_data["function"]

Parameters
