测试ETD盒子是否正常运行​

#首先电脑需要连接盒子同一个网络（WIFI）
from etherdata_sdk.json_rpc import JsonRpcMethods

client = JsonRpcMethods("http://192.168.51.100:8547")
print(client.block_number())

创建账户​

from etherdata_sdk.account import Account

account = Account()
# 通过助记词
# mnemonic="math bridge crew tumble sing leopard alter bargain knife siren morning daring"
# account.create_private_key_from_mnemonic(mnemonic)

# 创建随机的account
account.create_random_private_key()
account.save(output_file="./private.key")

交易​

from etherdata_sdk import Transaction
from etherdata_sdk.account import Account

account = Account()
# 读取key
account.read_private_key_from_file("private.key")


from_account = account
to_account = Account().create_random_private_key()

transaction = Transaction(to=to_account.address, value=30000, gas=1000, gas_price=300, nonce=1, chain_id=3101)

signed = from_account.sign_transaction(transaction)

查询余额​

from etherdata_sdk.account import Account
from etherdata_sdk.json_rpc import JsonRpcMethods

account = Account()
# 读取key
account.read_private_key_from_file("private1.key")

from_account = account

client = JsonRpcMethods("http://192.168.51.100:8547")
balance = client.get_balance(address=from_account.address, tag="latest")
print(balance)
