get-erc20-balances

this Python package provides functionality to generate Ethereum addresses from a mnemonic phrase and check the ETH balance as well as ERC-20 token balances associated with a given Ethereum address.

Installation

To use this package, you need to install the required libraries using pip. Open a terminal and run the following command:

pip install web3 hdwallet

eth_gen Module

Functions

generate_ethereum_address_from_mnemonic(mnemonic, path)

Generates an Ethereum address from a given mnemonic and derivation path.

• mnemonic: The mnemonic phrase.
• path: The derivation path.

ethereum_addresses(mnemonic, depth=1)

Generates a list of Ethereum addresses for different derivation paths.

• mnemonic: The mnemonic phrase.
• depth: The depth of address generation (default is 1, max is 20).

eth_balance Module

Functions

get_eth(url, address)

Retrieves the ETH balance of a given Ethereum address.

• url: The Web3 provider URL.
• address: The Ethereum address.

get_erc20tokens(url, address)

Retrieves the balances of ERC-20 tokens associated with a given Ethereum address.

• url: The Web3 provider URL.
• address: The Ethereum address.

Example Usage (example.py)

Set your mnemonic phrase and Web3 provider URL, then call the functions to get ETH and ERC-20 token balances.

# Set your mnemonic phrase and Web3 provider URL
mnemonic = "abadon abadon abadon abadon abadon abadon abadon abadon abadon abadon abadon abadon"
url = "https://rpc.notadegen.com/eth"
ethAddress = "0x95222290DD7278Aa3Ddd389Cc1E1d165CC4BAfe5"

# Get ETH balance
ethBalance = get_eth(url, ethAddress)
print(ethBalance)

# Get ERC-20 token balances
erc20TokenBalances = get_erc20tokens(url, ethAddress)
print(erc20TokenBalances)

# Combined result (ETH balance + ERC-20 token balances)
combinedResult = ethBalance + erc20TokenBalances
print(combinedResult)

Note: Ensure you have a reliable Web3 provider. You can find free Ethereum nodes at Chainlist.
