trace_transaction on BNB Chain
Returns the parity/trace-module call traces for a single transaction. Used by tooling built around the trace_* namespace. Heavy; needs a free API key.
The Erigon/Parity-lineage trace_ equivalent of debug_traceTransaction, returning a flat list of trace actions. Choose it when your tooling expects trace_* output; otherwise debug_'s callTracer is more widely supported.

Tracing on BNB Chain
BNB Chain supports geth-style debug_ tracing. Because blocks are sub-second, debug_traceBlockByNumber returns quickly per block but you'll need many more blocks to cover a time window.

trace_transaction on BNB Chain — FAQ
How do I call trace_transaction on BNB Chain?
POST a JSON-RPC 2.0 request with "method": "trace_transaction" to NodeFlare's BNB Chain endpoint at https://rpc.nodeflare.app/bnb/v1/YOUR_KEY. This method requires a free API key — it is not available on the public endpoint.
What does trace_transaction cost on the free tier?
trace_transaction is weighted at 100 compute units per call. The free tier includes 2,000,000 CU/month, so that is roughly 20,000 trace_transaction calls per month — no credit card.
Is trace_transaction available on the public BNB Chain endpoint?
No. trace_transaction is a heavy method and requires a free API key. The public no-key endpoint serves standard read methods; create a free key to unlock trace_transaction, eth_getLogs, trace_* and debug_*.
Anything BNB Chain-specific to know when using trace_transaction?
BNB Chain supports geth-style debug_ tracing. Because blocks are sub-second, debug_traceBlockByNumber returns quickly per block but you'll need many more blocks to cover a time window.
