Do I need a blockchain node to use Fiber Network?
No. You can connect to the API without needing a blockchain node.
To do so, you can follow our Getting started guide.
Can I connect using Websockets?
Yes, you can use the JSON-RPC API over Websocket. You can find more information in the JSON-RPC API section. If you don't have strict requirements to use Websockets, we recommend using gRPC instead, as it's a little bit faster and more efficient.
Which networks does Fiber support?
For now, only Ethereum. Support for other EVM chains (Polygon, BSC) is planned.
