A client-only EVM-based block-explorer via RPC calls.

Simple Blockexplorer

This blockexplorer is a client-only (i.e. serverless) block explorer, where the client makes RPC calls directly to the blockchain node.

• Search bar to directly query an address / transaction / block.
• Changeable RPC URL with chain ID verification.
• Custom known addresses for better UX.
• Light & dark theme support.

Here are some example RPC urls and chain IDs
