    I have a finished Solidity smart contract that taxes every transaction 4%. 2% burn, 2% reward. I need to have the contract modified so that the tax and burn functions stop when the total supply of the coin reaches 100 million. This is not a big project, it only requires adding one single function to the already existing code. Should be a quick project for the Solidity professionals.
