Notes

Combines trace_block functionality with the ability to request vmTrace and stateDiff.
Very resource-intensive, especially with vmTrace. Use with caution on blocks with many transactions.
All trace requests are routed to a an archive node with full trace support.
An empty block returns an empty array.

trace_call

Executes a call and returns the requested traces. This is similar to eth_call but with tracing support.

trace_filter

Returns traces matching a filter. Allows searching for specific trace activity across a range of blocks.
