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

## Hardhat Local

http://localhost:8545
31337

## Avalanche

https://api.avax.network/ext/bc/C/rpc
43114

## Polygon

https://polygon-rpc.com
137

Clone the repo, and just yarn. Then, yarn dev to run the web app locally. Enter the RPC url and the chain ID to the settings button on the top right.

The connected node must support the following:

• eth_blockNumber
• eth_call
• eth_getBalance
• eth_getCode
• eth_getBlockByHash
• eth_getBlockByNumber
• eth_getTransactionByHash
• eth_getTransactionByBlockHashAndIndex
• eth_getTransactionByBlockNumberAndIndex
• eth_getTransactionReceipt
• eth_getUncleByBlockHashAndIndex
• eth_getLogs
