编写 EVM 数据函数

def _(chain_id, block_id, token, holder):
    from leafage import EVM

    evm = EVM(chain_id, block_id)
    balance = evm.call(token, "balanceOf(address)(uint256)", [holder])
    return {
        "id": holder,
        "chain_id": chain_id,
        "block_id": block_id,
        "token": token,
        "balance": balance,
    }
