APIs

The differences between Monad and the standard Geth client are described here: https://docs.monad.xyz/reference/rpc-differences

JSON-RPC

Monad supports most of the JSON-RPC methods available in Geth. You can find the official documentation here

The linked documentation also includes cURL examples where you just need to replace the RPC URL, e.g:

curl --request POST \
     --url <TRITON_URL> \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "id": 0,
  "jsonrpc": "2.0",
  "method": "eth_blockNumber",
  "params": []
}
'

Expected result:

{
    "jsonrpc": "2.0",
    "result": "0x23feb61",
    "id": 0
}

Websocket

The websocket API is also available in Monad. You can find the official documentation here

See an example below how to test websocket using the wscat utility:

Install node-ws in Linux:

sudo apt update
sudo apt install node-ws

Subscribe to websockets:

wscat -c wss://<TRITON_URL>
Connected (press CTRL+C to quit)
> { "id": 1, "jsonrpc": "2.0", "method": "eth_subscribe", "params": ["newHeads"] }
