Broadcast a signed transaction

Broadcast a pre-signed transaction directly to the blockchain network. This endpoint bypasses the standard workflow orchestration and policy evaluation, executing the transaction as-is.

Request Body

Field	Type	Required	Description
`signedTransactionHex`	string	Yes	RLP-encoded signed transaction (0x prefix)
`chainId`	number	Yes	Blockchain network ID (must match transaction)

Transaction Flow

Decode — Parse and validate the signed transaction hex
Verify — Confirm chain ID matches the transaction
Balance Check — Verify sender has sufficient funds/gas
Broadcast — Submit transaction to blockchain network
Return — Provide transaction hash and metadata

Important: This endpoint does NOT perform policy evaluation or trigger approval workflows. The transaction is broadcast exactly as signed.
