Python查询钱包地址余额

需要用到三方库

1、查询 BSC 链 BNB 余额

from web3 import Web3
from web3.middleware import geth_poa_middleware
# r('https://bsc-dataseed3.binance.org/'))
bsc_url = 'https://bsc-dataseed.binance.org/'
web3 = Web3(Web3.HTTPProvider(bsc_url))
web3.middleware_onion.inject(geth_poa_middleware, layer=0)
wallet_address = '你的钱包地址'
# Web3.toChecksumAddress(wallet_address)
checksum_address = Web3.to_checksum_address(wallet_address)
balance = web3.eth.get_balance(checksum_address)

# Convert the balance from wei to BNB
balance_bnb = web3.from_wei(balance, 'ether')

# Print the balance
print(f"Wallet balance: {balance_bnb} BNB")

2、查询 BSC 链 USDT 余额

from web3 import Web3
from web3.middleware import geth_poa_middleware

bsc_url = 'https://bsc-dataseed.binance.org/'
web3 = Web3(Web3.HTTPProvider(bsc_url))
web3.middleware_onion.inject(geth_poa_middleware, layer=0)

wallet_address = '你的钱包地址'
checksum_address = Web3.to_checksum_address(wallet_address)

# USDT contract address on BSC
usdt_contract_address = '0x55d398326f99059ff775485246999027b3197955'

# ABI for the balanceOf function
usdt_abi = [{"constant":True,"inputs":[{"name":"_owner","type":"address"}],"name":"balanceOf","outputs":[{"name":"balance","type":"uint256"}],"payable":False,"stateMutability":"view","type":"function"}]
usdt_contract_address_checksum = Web3.to_checksum_address(usdt_contract_address)
usdt_contract = web3.eth.contract(address=usdt_contract_address_checksum, abi=usdt_abi)

# Get the balance of the wallet address
balance = usdt_contract.functions.balanceOf(checksum_address).call()

# Convert the balance from wei to USDT
balance_usdt = web3.from_wei(balance, 'ether')

# Print the balance
print(f"Wallet balance: {balance_usdt} USDT")
