EGLD 转账(移动余额交易)

原文：https://docs.elrond.com/developers/gas-and-fees/egld-transfers

## 公式

对于 EGLD 转账，处理的实际气体成本易于精确确定，因为它仅包含值移动和数据处理组件。根据之前描述的公式，气体极限应设置为实际气体成本:

tx.gasLimit = 
    networkConfig.erd_min_gas_limit + 
    networkConfig.erd_gas_per_data_byte * lengthOf(tx.data) 

例子

鉴于:

networkConfig.erd_min_gas_limit is 50000
networkConfig.erd_gas_per_data_byte is 1500
networkConfig.erd_min_gas_price is 1000000000

tx1.data = ""
tx1.gasPrice = networkConfig.erd_min_gas_price

tx2.data = "Hello world!"
tx2.gasPrice = networkConfig.erd_min_gas_price 

然后:

tx1.gasLimit = 50000

tx2.gasLimit 
    = 50000 + 1500 * len("Hello world!") 
    = 68000 

此外，费用如下:

fee(tx1) 
    = tx1.gasLimit * tx1.gasPrice 
    = 50000 * 1000000000
    = 50000000000000 atoms of EGLD
    = 0.00005 EGLD

fee(tx2) 
    = tx2.gasLimit * tx2.gasPrice 
    = 68000 * 1000000000
    = 68000000000000 atoms of EGLD
    = 0.000068 EGLD
