Web3.py

It is possible to connect to the Nethermind node using web3.py (python web3.js implementation). You will need to have web3.py installed using following guides:

• ​https://github.com/ethereum/web3.py​

• ​https://web3py.readthedocs.io/en/stable/quickstart.html​

You may use below script in order to check your connection. Please make sure you have enabled JSON RPC module, this can be done by passing flag --JsonRpc.Enabled true to either Nethermind.Launcher or Nethermind.Runner

from web3.auto import w3
​
connected = w3.isConnected()
print(connected)
​
if connected and w3.clientVersion.startswith('Nethermind'):
    client = w3.clientVersion
    print(client)
​
else:
    client = None
    print(client)

You should see the following output (depends on the node version):

True
