Payz payments solution (PAYZ) is a seamless integration that gives e-commerce businesses the power to accept digital currencies. The PAYZ Platform is a payment processor solution that enables merchants to accept multiple cryptocurrencies from buyers while receiving their funds in fiat currency. We aim to establish our solution as the best in the market.
You can use the PAYZ token in the platform by spending it on merchants that support PAYZ Tokens. You can also sell the token on open exchanges, or just hodl it for future use. PAYZ is a payment system that enables you to use the coin and spend it independently alongside a system that grows in synergy with the coin.

StandardToken.transfer(address,uint256) (#125-135) compares to a boolean constant:
-require(bool)(tokenBlacklist[msg.sender] == false) (#126)
StandardToken.transferFrom(address,address,uint256) (#142-153) compares to a boolean constant:
-require(bool)(tokenBlacklist[msg.sender] == false) (#143)
Remove the equality to the boolean constant.

Pragma version^0.4.24 (#1) allows old versions
solc-0.4.24 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
