MetaFootya believes in the power of soccer, the world's universal language, to create positive change for individuals, families, communities, and the world. We envision a more inclusive world where everyone has the opportunity to reach their full potential. Moreover, it can be seen that football clubs and cryptocurrency so keen to play ball together. The reason is it provides much-needed revenue to one and all-important exposure and status to the other. Everyone can benefit from both the entertainment of football and the profit of crypto investments. As the MetaFooty team, our mission is for the blockchain ecosystem to take its own share of the huge football industry. The synthesis of football and blockchain provides huge growth potential for the project, considering anyone with an interest in these two fields. MetaFooty allows Binance Smart Chain (and later Solana Network) users to earn passive income while having fun, and keeps the community strong with collective events.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains
Contract ownership is not renounced (belongs to a wallet)
Pragma version0.8.16 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.16 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.
