Working with Zymbit's Wallet Python SDK
Updated: 2023-05-11
What is Zymbit’s Wallet SDK?
Blockchain accounts, signatures, and transactions have an additional layer of complexity over traditional cryptographic keys and signatures. Our Wallet SDK aims to abstract away this complexity, enabling you to create and manage multiple blockchain wallets and seamlessly interact with smart contracts in your applicaitons without having to deal with their technical intricacies.
These examples are derived from the documentation.
Installation
pip install zymbitwalletsdk
ETH Keyring Examples
Creating an ETH Keyring
If you have an existing wallet on your module, you can initialize an ETH Keyring using either the wallet name or its corresponding master slot. Here’s how:
from zymbitwalletsdk import ZymbitEthKeyring
keyring = ZymbitEthKeyring(wallet_name = "MyExampleWallet")
print(keyring)
or
from zymbitwalletsdk import ZymbitEthKeyring
keyring = ZymbitEthKeyring(master_slot = 16)
print(keyring)
Output:
ZymbitEthKeyring(
type = ETH
base_path = m/44'/60'/0'/0
wallet_name = MyExampleWallet
master_slot = 16
base_slot = 20
accounts = [
(Path: m/44'/60'/0'/0/0, Address: 0x93D458d6B14A02943A07708a24D8A9F142Fc5A00, Slot: 26)
(Path: m/44'/60'/0'/0/1, Address: 0x9fB80f688e4a4f68cd94e0DD4263B03cA7CC52ff, Slot: 27)
(Path: m/44'/60'/0'/0/2, Address: 0x29e9f7D65886c6c1e164AFd4823A477eB0F1F75a, Slot: 28)
]
)
Adding Accounts
There are three methods you can use to add accounts. Here is how you use them:
from zymbitwalletsdk import ZymbitEthKeyring
keyring = ZymbitEthKeyring(master_slot=16)
print(keyring.add_account(index = 12))
print(keyring.add_accounts(n = 2))
print(keyring.add_accounts_list(index_list = [15, 26]))
print(keyring.get_accounts())
Output:
(Path: m/44'/60'/0'/0/12, Address: 0x092aa5e156F4FE5b3944B8A2421E45a23B8d1B00, Slot: 34)

Remove an Account
If you want to remove an account from a keyring, here is how to do it:
from zymbitwalletsdk import ZymbitEthKeyring, ZymbitKeyringManager, EthConnect
keyring = ZymbitEthKeyring(wallet_name = "MyExampleWallet")
accounts = keyring.get_accounts()
print(accounts)
account_to_remove = accounts[2]
keyring.remove_account(address = account_to_remove.address)
accounts = keyring.get_accounts()
print(accounts)
Output:

Contract Transactions (EIP-1559)
For the deploying and executing contract examples, we will be using the following solidity contract:
pragma solidity >=0.7.0 <0.9.0;
contract Counter {
uint public counter;
event IncrementedCounter (uint counter, address indexed sender);
constructor(uint initial) {
counter = initial;
}
function increment_counter() public {
counter += 1;
emit IncrementedCounter(counter, msg.sender);
}
}
Create an ETH Deploy Contract Transaction
To deploy a contract, you need to save the contract ABI as a JSON file and the hex encoded bytecode as a txt file on your Pi’s local file system. Once you have done that, you can deploy a contract like this:
from zymbitwalletsdk import ZymbitEthKeyring, ZymbitKeyringManager, EthConnect
from web3 import Web3
import binascii
web3 = Web3(Web3.HTTPProvider("YOUR ETH NODE'S HTTPS ENDPOINT"))
keyring = ZymbitEthKeyring(wallet_name = "MyExampleWallet1")
sending_account = keyring.get_accounts()[1]
chain_id = web3.eth.chain_id
nonce = web3.eth.get_transaction_count(sending_account.address)
value_in_wei = EthConnect.eth_to_wei(1)
recipient = keyring.get_accounts()[0].address
gas_price = web3.eth.gas_price
gas_limit = 2100000
transaction = EthConnect.create_deploy_contract_transaction(chain_id = chain_id, nonce = nonce, contract_abi_path = './ABI.json', contract_bytecode_path = "./bytecode.txt", constructor_args = [0], max_fee_per_gas = gas_price, gas = gas_limit)
signed_transaction = EthConnect.sign_transaction(transaction, keyring, address = sending_account.address)
serialized_transaction = EthConnect.rlp_serialize_transaction(signed_transaction)
transaction_result_hash = web3.eth.send_raw_transaction(serialized_transaction)
print("Transaction broadcast hash:\n%s" % binascii.hexlify(transaction_result_hash).decode("utf-8"))
Output:

Create an ETH Execute Contract Transaction
In this example, we are going to invoke the increment_counter function in our deployed contract. Here’s how to do it:
from zymbitwalletsdk import ZymbitEthKeyring, ZymbitKeyringManager, EthConnect
from web3 import Web3
import binascii
web3 = Web3(Web3.HTTPProvider("YOUR ETH NODE'S HTTPS ENDPOINT"))
keyring = ZymbitEthKeyring(wallet_name = "MyExampleWallet1")
sending_account = keyring.get_accounts()[1]
chain_id = web3.eth.chain_id
nonce = web3.eth.get_transaction_count(sending_account.address)
value_in_wei = EthConnect.eth_to_wei(1)
contract_address = "0xE575A1F131be23223ee59f00379FF13B913E9063" # The deployed contract's address on the Sepolia test network
gas_price = web3.eth.gas_price
gas_limit = 2100000
transaction = EthConnect.create_execute_contract_transaction(chain_id = chain_id, nonce = nonce, contract_abi_path = './ABI.json', contract_address = contract_address, function_name= "increment_counter", args = [], max_fee_per_gas = gas_price, gas = gas_limit)
signed_transaction = EthConnect.sign_transaction(transaction, keyring, address = sending_account.address)
serialized_transaction = EthConnect.rlp_serialize_transaction(signed_transaction)
transaction_result_hash = web3.eth.send_raw_transaction(serialized_transaction)
print("Transaction broadcast hash:\n%s" % binascii.hexlify(transaction_result_hash).decode("utf-8"))
Output:
Transaction broadcast hash:
