Transaction Broadcasting

Overview
POST Submit a Signed Transaction (V1)
POST Submit a Signed Transaction (V2)


Overview

The Ubiquity Universal API endpoint in this section allows you to broadcast transactions.

As with all Ubiquity Universal API endpoints, this provides a standard format to obtain consistent information across multiple protocols


POST Submit a Signed Transaction (V1)

https://ubiquity.api.blockdaemon.com/v1/{protocol}/{network}/tx/send

Broadcasts a signed transaction. A successful transaction may still be rejected on-chain or not processed due to a too low fee. You can monitor successful transactions through Ubiquity WebSockets.
