Hello Solidity devs. Do anyone have any suggestions on what I can do to minimize the energy consumption when interacting with a smart contract on the Tron network?

Will it cost more energy to use for example uint256 than uint64?
Nov 3, 2020, 1:12 PM
Yes
Nov 3, 2020, 1:13 PM
If I declare a variable as just uint it will automatically be a uint256?
Nov 3, 2020, 1:14 PM
Yes
Nov 3, 2020, 1:15 PM
So integers that I know will just be short number I better set like uint8?
Nov 3, 2020, 1:15 PM
Yes
btw uint256 var1, uint8 var2, uint8 var3 take low memory than, uint8 var1, uint256 var2, uint8 var3
Nov 3, 2020, 1:17 PM
How do you mean, like the order they are declared?
Nov 3, 2020, 1:41 PM
Does it really depends on the order?
Nov 3, 2020, 1:49 PM
Yep

Any specific reason?

Google it. Don’t have time

I have been trying to find some info about this on Google, please share the info for this whenever you have time.

There is info about it in zombie tutorials
Crypto zombies. Probably lvl2

I'm not sure I understand. A contract creation is always a Create opcode (or create2), if that's what you mean.
But, yes, you can call a function with the contract bytecode and ask the function to deploy that bytecode
(I think, unsure how to do it in reality)

For your usecase, that's the best choice
