trace_callMany - Validation Cloud

Executes several message calls in sequence against the same state and returns the traces of each, without creating transactions on the block chain. This method will use 80 Compute Units.

This method is served by nanoreth, the HyperEVM archive client, and works for any block back to genesis. On blocks that carry a HyperCore deposit, block-level traces include the deposit as their first entry; see Overview.

Parameters

array - A list of [transaction, traceTypes] pairs, executed in order, each later call seeing the state changes of the earlier ones:
- transaction - Object - The call object with the same fields as eth_call (from, to, gas, gasPrice, value, data).
- traceTypes - Array - Any of trace, vmTrace, stateDiff.
QUANTITY | TAG - Integer block number, or the string "latest", "earliest" or "pending".

Returns

array - One result per call, each with output, trace, stateDiff and vmTrace as requested.
