web3client 0.3.4

Client to interact with multiple EVM blockchain

Easy to use Python client to interact with multiple EVM blockchain.

Features

• Easily create a client to interact with EVM-compatible chains.
• Preconfigured for the most popular chains: Ethereum, Binance, Avalanche, Cronos, etc.
• Support for ERC20 operations, using the token name (e.g. USDC) instead of address.
• Exposes the underlying web3.py client to allow for more flexibility

Examples

Get the latest block on both Ethereum, BNB Chain and Avalanche:

from web3factory.factory import make_client

eth_block = make_client('ethereum').getLatestBlock()
bnb_block = make_client('binance').getLatestBlock()
avax_block = make_client('avalanche').getLatestBlock()

Get the USDC balance of the Ethereum foundation, and the BUSD balance of Binance's hot wallet:

from web3factory.factory import make_erc20_client

ef_address = "0xde0b295669a9fd93d5f28d9ec85e40f4cb697bae"
ef_usdc = make_erc20_client("USDC", "ethereum").balanceOf(ef_address) / 10**6

bw_address = "0x8894e0a0c962cb723c1976a4421c95949be2d4e3"
bw_busd = make_erc20_client("BUSD", "binance").balanceOf(bw_address) / 10**18

Install

pip3 install -U web3client
