# Broadcast signed transactions

> <Note>This operation is only applicable to the staking scenarios.</Note>
This operation broadcasts a list of signed transactions. 

If you set `auto_broadcast` to `false` when [creating a staking activity](https://www.cobo.com/developers/v2/api-references/staking/create-stake-activity), the transaction will not be submitted to the blockchain automatically after being signed. In such cases, you can call this operation to broadcast the transaction to the blockchain.

A transaction can only be broadcast if its status is `Broadcasting`.
