我正在尝试将 EGLD 值（例如 1.5 EGLD）发送到帐户/智能合约，但在某些情况下似乎只允许 BigUInt 类型。这个值是如何工作的以及我应该如何正确地格式化它？

我尝试使用以下Python代码进行ESDT代币发行交易

from erdpy.accounts import Account, Address
from erdpy.proxy import ElrondProxy
from erdpy.transactions import BunchOfTransactions
from erdpy.transactions import Transaction
from erdpy.wallet import signing


TOKEN_NAME = b"Cowdings"
TOKEN_SYMBOL = b"MOO"

DECIMALS = 18
SUPPLY = 1000 * 10**DECIMALS


def hex_string(s: str) -> str:
    assert type(s) == bytes, "Make sure everything is bytes data or utf-8 encoded"
    return hexlify(s).decode("ascii")


def hex_int(i: int) -> str:
    assert type(i) == int, "Make sure everything is bytes data or utf-8 encoded"
    return hex(i)[2:]


proxy = ElrondProxy("https://devnet-gateway.elrond.com")
sender …

当我尝试使用以下命令从这里构建乒乓球智能合约时：

erdpy build contract

我没有得到以下预期输出：

INFO:projects.core:WASM file generated: output/ping-pong.wasm

因为文件中出现以下错误sc_results.rs：
