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.

CLI Example

ORBITER_PRIVATE_KEY=... orbiter bridge sign-broadcast \
  --template-file ./template.json \
  --chain-id 42161 \
