is_yearn_registry_excluded_vault

Documentation for eth_defi.erc_4626.vault_protocol.yearn.endorsement.is_yearn_registry_excluded_vault function.

is_yearn_registry_excluded_vault(chain_id, vault_address, *, exclusions=None)

Check whether Yearn excludes a vault from its primary product list.

The check normalises EIP-55 casing. Supplying an index lets migrations use one reviewed registry snapshot for their complete run. Omitting it may trigger a cached HTTP lookup in scanner callers.

Parameters

• chain_id (Optional[int]) – EVM chain identifier for the vault deployment, if known.

• vault_address (eth_typing.evm.HexAddress) – ERC-4626 vault contract address.

• exclusions (Optional[frozenset[tuple[int, eth_typing.evm.HexAddress]]]) – Optional pre-fetched Yearn primary-list exclusion index. Omitting it may trigger a cached HTTP lookup.

Returns

True when the registry records a primary-list exclusion.

Return type

bool
