JSON-RPC Providers

The Polkadot-API entry point is createClient(provider). It takes a JsonRpcProvider that connects to a JSON-RPC endpoint, enabling Polkadot-API to interact with the chain.

Providers

We have mainly two first-class providers:

• Smoldot Provider, connecting to a local instance of Smoldot, Polkadot's light client.
• WebSocket Provider, connecting to a JSON-RPC server through WebSocket.

Enhancers

The JsonRpcProvider interface is simple and unopinionated. This lets you create enhancers that add functionality, which might be useful for observability, debugging, etc.

PAPI has a Logs Provider and Recorder, allowing to capture JSON-RPC messaging logs, useful for debugging and/or analytics.
