pub async fn fetch_account_fields_bulk<P: Provider<AnyNetwork>>(
provider: &P,
addresses: &[Address],
block: BlockId,
) -> StorageFetchResult<Vec<(Address, AccountFieldsSample)>>Expand description
Fetch balance + code hash for many accounts in one eth_call.
BALANCE/EXTCODEHASH read other accounts, so only one code override
(the extractor host, at MULTICALL3_ADDRESS) is injected and the
queried accounts are untouched. Costs ~5.3k gas per address (two cold
account accesses), so thousands of accounts fit in one call. Querying the
host address itself reports the extractor’s own code hash — give it a
dedicated eth_getProof instead.
