This extension adds a new panel to Chrome DevTools that inspects JSON-RPC messages sent with Polkadot-API. It is useful when debugging applications that speak to Substrate-based chains over JSON-RPC.

Features:

- Groups multiple JSON-RPC connections per tab, so you can inspect all traffic for a page in one place.

- Provides an improved, structured JSON view for requests and responses, making complex payloads easier to read.

- Understands chainHead JSON-RPC methods so you can inspect subscriptions, operations and their lifecycle.

- Lets you follow pinned blocks and track the operations executed on each tracked block.
