EGLD transfers (move balance transactions)

Formula​

For EGLD transfers, the actual gas cost of processing is easy to determine precisely, since it only contains the value movement and data handling component. The gas limit should be set to the actual gas cost, according to the previously depicted formula:

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

Examples​

Given:

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

Then:

tx1.gasLimit = 50000

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

Furthermore, the fee would be as follows:

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
