Question

its working perfectly in 0.6.4 but getting error in 0.8.1 v

  function setMinbalance(uint256 minimumBalanceInfinney) public onlyOwner {
            
       minBalanceForAccounts = minimumBalanceInfinney * 1 finney ;
   }

Answer 1

The finney and szabo denominations are removed. They are rarely used and do not make the actual amount readily visible. Instead, explicit values like 1e20 or the very common gwei can be used.

Solution:

Replace 1 finney for 1e15 (because 1 finney == 1000000000000000 wei).

minBalanceForAccounts = minimumBalanceInfinney * 1e15 ;
