description	Sign a tx template locally and broadcast it to the chain.

Orbiter Sign Broadcast

Sign a transaction template with a local private key and broadcast it to the chain.

When to Use

• You already have a transaction template (from orbiter_sign_template or external sources)
• You want a one-step sign + broadcast

Inputs

• template (string, JSON)
• templateFile (string, file path)
• privateKey (string, optional, recommended via ORBITER_PRIVATE_KEY)
• chainId (string)
• rpcUrl (string, optional)
• chain (string, optional)

Behavior

• If nonce/gasLimit/fee fields are missing, the command auto-enriches them when rpcUrl (or chain) is provided.
• If from is missing, it is derived from the private key.

Outputs

• txHash

Security Notes

The private key is only used for local signing. It is never written to disk or sent over the network.
