AUDIT: We need Audit for our smart contract. FIXES: 1. We have working smart contract on mainet and testnet 2. Couple of functions are not work for me: 1) Transferfrom 2) Burnfrom 3) Frozen account still able to transfer token - (need to check and fix if needed) Limited account still able to transfer tokens above the address limits - (need to check and fix if needed) 4. We need to add couple additional functions: 1) Limit our PRIMARY (list in advance) wallets to 300000 MDZA / day 2) Price: Our token act like stable coin on the pre sale stage. E.g we allow to spend our token by purchasing goods and services. We want to set 1MDZA=0.10$ price to be displayed by etherscan. (of course this is should be adjustable by us and related on ICO / Pre sale stages). 5. The fixed smart contract should be optimized for last compiler. 6. The fixed smart contract should be gas-cost optimized. UPGRADE: 1. Our smart contract deployed by using truffle. 2. If i understand, there are some function that can be used to update it without changing the smart contract address. 3. We prefer not to change the current smart contract address. (if i understand there are new DELEGATECALL opcode that allow that). 4. We need closed accompanying and supporting during the upgrade process.

Hi, I can do all of this for you except: 2) Price: Our token act like stable coin on the pre sale stage. E.g we allow to spend our token by purchasing goods and services. We want to set 1MDZA=0.10$ price to be displayed by etherscan. Stable Coins are fairly difficult to implement - if you want physical goods set to a fixed amount of your tokens I would do that through your websites pricing. and 3. We prefer not to change the current smart contract address. DELEGATE CALL is useful for keeping the smart contract address the same but that functionality needs to be done before you publish the contract. I can make sure your next contract is updatable though
