Gas related

[Magicianhax]

I am here to seek a bit of help. I am trying to create a memecoin and a game contract where you send the memecoin I’ve created, and it will either double or result in nothing. The contract is deployed, but it needs some gas to transact. However, I just realized I can’t load gas into the contract because MITO is non-transferable. I’m seeking help because I can’t find any documentation related to this.

Proposal for Gas Optimization

I would like to suggest the following optimizations to improve gas efficiency in the smart contracts:

1. Replace dynamic arrays with static arrays:

   • Dynamic arrays consume more gas compared to static arrays. Where possible, replace dynamic arrays with fixed-size arrays. Example:

     // Before:
     uint[] public dynamicArray;
     
     // After:
     uint[10] public staticArray; // Fixed size

2. Use calldata instead of memory for public functions:

   • Parameters passed to public functions can be marked as calldata to reduce memory allocation. Example:

     // Before:
     function processData(uint[] memory data) public {
         // logic
     }
     
     // After:
     function processData(uint[] calldata data) public {
         // logic
     }

3. Optimize loop logic:

   • Reduce the number of iterations in loops by precomputing values or simplifying logic. Example:

     // Before:
     for (uint i = 0; i < data.length; i++) {
         total += data[i];
     }
     
     // After:
     uint len = data.length;
     for (uint i = 0; i < len; i++) {
         total += data[i];
     }

4. Refactor unnecessary storage reads:

   • Cache storage variables in memory to avoid repeated reads. Example:

     // Before:
     total += balances[user];
     total += balances[user];
     
     // After:
     uint balance = balances[user];
     total += balance;
     total += balance;

Request for Feedback

Please let me know if these changes align with your optimization goals. I am happy to assist further in implementing or testing these suggestions.
