Broadcast Transaction (Commit)
broadcast_tx_commit request type
Use a freshly signed base64 transaction for each request. This legacy synchronous send is still documented, but send_tx is the preferred path for new integrations, and the sample payload is illustrative only.
Submit a freshly signed transaction and wait for its commit — the legacy synchronous send, superseded by `send_tx`. Default examples are illustrative only and are not reusable signed payloads.
