CryptoZoon is inspired by Pokemon Story, our mission is to build a comprehensive platform of digital monsters that will enable millions of individuals to participate in the NFT and blockchain-based gaming world in a simple, creative, and enjoyable way.
CryptoZoon will be the first ecosystem to combine the greatest aspects of gaming and digital collectibles, transforming it into the digital creatures universe. With CryptoZoon, Players can use their ZOANs to fight monsters, collect, grow, and join training (battle each other).
Yaki Gold is the second BEP-20 token produced from CryptoZoon ecosystem. YAG will play a variety of functions in CryptoZoon's working mechanism, including a requirement for farming NFT, prizes from Fight Monsters, a currency for buying products in future, and so on.

Pragma version^0.6.0 (#5) allows old versions
Pragma version>=0.6.2<0.8.0 (#83) is too complex
Pragma version^0.6.0 (#249) allows old versions
Pragma version^0.6.0 (#327) allows old versions
solc-0.6.6 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.
