Integrating with eth-account

Privy EVM wallets natively integrate with the Python eth-account library, allowing you to use the library's interfaces for signing messages, signing typed data, sending transactions, and more.

To integrate with eth-account, first install the library as a dependency:

pip install privy-eth-account

Then, use Privy's create_eth_account function to initialize an instance of an Account for an EVM server wallet. As parameters to this function, pass:

Parameter	Type	Description
client	PrivyHTTPClient	Instance of the Privy HTTP client for your app.
address	str	Ethereum address of the wallet.
wallet_id	str	ID of the wallet.

Here's an example showing how to integrate with eth-account:

from privy_eth_account import create_eth_account, PrivyHTTPClient
from eth_account.messages import encode_typed_data, encode_defunct

# Initialize your Privy client
client = PrivyHTTPClient(
    app_id="YOUR_APP_ID",
    app_secret="YOUR_APP_SECRET",
    authorization_key="YOUR_AUTHORIZATION_KEY"
)

# Create an account instance for a wallet
wallet_id = "insert-wallet-id"
wallet_address = "insert-wallet-address"
account = create_eth_account(client, wallet_address, wallet_id)

Once you created an account instance, you can use it to sign messages, sign transactions, and sign typed data:

Sign a message

# Signing a message (personal_sign)
message = encode_defunct(text="Hello, Privy!")
signed_message = account.sign_message(message)
print(f"Signed message: {signed_message}")

Sign a transaction

# Signing a transaction
transaction = {
    "to": "0x123...789",
    "value": 100,
    "chain_id": 8453
}
signed_tx = account.sign_transaction(transaction)
print(f"Signed transaction: {signed_tx}")

    },

# Sign the typed data using the full_message parameter
signed_typed_data = account.sign_typed_data(full_message=full_message)
print(f"Signed typed data: {signed_typed_data}")
