Metamask Business Problems for Truffle and Ganache Kit
As a developer who uses a truffle and ganache kit for ethereum’s smart contracts, I am facing the problem with funds and the counter increases. In this article, We Will Go Into the Problem and Explore Possible Solutions.
Question
When creating a new contract for ganache or remix, you need to call the setbalance to set your account’s original balance to the specific amount. However, if you do not update the balance after the transaction, the meter not increase properly.
Here is an Example of how it might look:
`Solidity
Pragma Solidity ^0.8.3;
contract counter {
Uint public meter = 0;
Function set balance () Public {
Request (MSG.Sender == Address (This), "Only the owner of the contract can call this function");
Counter ++;
Balance = msg.value;
}
}
In The Example Above, We Increase the Variable «Counter» Every time the transaction is made «Setbalance». However, if you make another transaction, first without updating the balance, the meter not increase properly.
Solution
To Solve This Problem, You Need to Call The Setbalance Feature Before Making Another Transaction. One way to do this is to use one feature that updates both «and» balance «.
`Solidity
Pragma Solidity ^0.8.3;
contract counter {
Uint public meter = 0;
Function set balance () Public {
Request (MSG.Sender == Address (This), "Only the owner of the contract can call this function");
Counter ++;
Balance = msg.value;
}
}
To use the updated feature «set balance», you need to call it before the other deal:
`Solidity
Pragma Solidity ^0.8.3;
contract counter {
Uint public meter = 0;
Function set balance () Public {
Request (MSG.Sender == Address (This), "Only the owner of the contract can call this function");
Counter ++;
Balance = msg.value;
}
}
Additional Solution
If you need to update Both Against and ‘Balance’ in One Transaction, You Can Use the Following Approach:
`Solidity
Pragma Solidity ^0.8.3;
contract counter {
Uint public meter = 0;
Function set balance () Public {
Request (MSG.Sender == Address (This), "Only the owner of the contract can call this function");
Counter ++;
Balance = msg.value;
}
}
In this case, you need to update the Variable Variable Before setting up the new value.
Conclusion
In Conclusion, it is not Possible to update Both «Against» and «Balance» in One Transaction Through Solidity. One of the Ways to Resolve This Issue is the «Setbalance» Feature Before Making Another Deal. Another approach is to use individual functions for updating thesis variables.
