How to Connect

Users that want to quickly send transactions to the BDN or stream transactions/blocks to their application have two options:

1. Gateway-API

2. Cloud-API

Gateway-API

Gateway-API peers with the user's node to quickly propagate both blocks and transaction to the node.

Cloud-API

The Cloud-API supports sending Ethereum transactions fast and subscribing to Transaction Streaming and Blocks Streaming.

Gateway-API vs Cloud-API

As a rule of thumb, it is faster to use the Gateway-API to send transactions and stream data because it provides a private entry point to the BDN and better latency. If a user does not have a Gateway installed, they can decide to use the Cloud-API instead of installing a Gateway. Users that require the best performance may decide to use both the Gateway-API and Cloud-API.

An additional Cloud-API endpoint is offered to enterprise customers (wss://<REGION>.<NETWORK>.blxrbdn.com/ws) for improved speed over the professional cloud API endpoint (api.blxrbdn.com).
