Method reference

trace_block

Parity-style traces for every transaction in a block: internal calls, contract creations, self-destructs, and rewards. Where receipts tell you a transaction succeeded, traces show the internal value flow it caused.

Indexers reconstructing internal transfers — analytics pipelines, subgraph-style systems, accounting tools — depend on the trace namespace. Like debug_*, availability depends on upstream node software and operator policy.

Example request

curl -s https://rpc.swiftnodes.io/rpc/eth?key=YOUR_API_KEY \
  -X POST -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"trace_block","params":["latest"]}'

Replace YOUR_API_KEY with your SwiftNodes key (free tier available).
