ThirdwebSDK.fromPrivateKey

Instantiate the ThirdwebSDK in read-write mode using a wallet’s private key.

All transactions made with this instance of the SDK will be signed using the private key.

Usage​

Provide the private key and the chain you want to use.

from thirdweb import ThirdwebSDK
from thirdweb.types import SDKOptions
from dotenv.main import load_dotenv
import os

load_dotenv()
secret_key = os.environ['SECRET_KEY']
private_key = os.environ['PRIVATE_KEY']

sdk = ThirdwebSDK.from_private_key(private_key, "mumbai", SDKOptions(secret_key=secret_key))

Configuration​

private_key​

The private key of the wallet you want to use to initiate transactions with.

Losing or leaking your private key will result in the loss of your funds.

    "private_key", # DANGER: This is a sensitive value that should be stored securely.
