Ok i’ll tell you more detail
I’m writing Log in contract. Are there any best practice for this? As i know log only accept log for 1 bytes. So i have to put all parametters in a single bytes. Thats why i asked this question.
For example with the question i ask, i want to log the value 00000000000000040000000000000007 To express the 2 value 4 and 7. So the log-reader can understand it is 2 params, each 64 bit.
So i think the question here should be how to express 2 uint64 in a single bytes?
