UpshiftMultiAssetHistoricalReader

Documentation for eth_defi.erc_4626.vault_protocol.upshift.vault.UpshiftMultiAssetHistoricalReader Python class.

class UpshiftMultiAssetHistoricalReader

Bases: eth_defi.vault.base.VaultHistoricalReader

Read Upshift multi-asset vault accounting history.

Upshift multi-asset vaults are not plain ERC-4626 share-token contracts. The vault proxy exposes accounting methods like getSharePrice() and getTotalAssets(), while lpTokenAddress() points to the ERC-20 share token used for name, symbol, decimals and total supply.

Relevant verified implementation: Upshift multiAssetVault.

Create a historical reader for Upshift multi-asset vaults.

Parameters

vault – Upshift vault adapter.
stateful – Whether to attach adaptive reader state used by the shared historical multicaller.

Attributes summary

`address`
`first_block`

Methods summary

`__init__`(vault, stateful)	Create a historical reader for Upshift multi-asset vaults.
`construct_multicalls`()	Construct historical multicalls for Upshift multi-asset vaults.
`process_result`(block_number, timestamp, ...)	Convert Upshift multi-asset multicalls to a vault price row.

__init__(vault, stateful)

Create a historical reader for Upshift multi-asset vaults.

Parameters

vault (eth_defi.erc_4626.vault_protocol.upshift.vault.UpshiftVault) – Upshift vault adapter.
stateful (bool) – Whether to attach adaptive reader state used by the shared historical multicaller.

process_result(block_number, timestamp, call_results)

Parameters

block_number (int) – Historical block number.
timestamp (datetime.datetime) – Naive UTC block timestamp.
call_results (list[eth_defi.event_reader.multicall_batcher.EncodedCallResult]) – Multicall results created by construct_multicalls().

Returns

VaultHistoricalRead with Upshift share price, NAV and LP token supply.

Return type

eth_defi.vault.base.VaultHistoricalRead
