Corona Crypto is a project that applies Blockchain technology to create an unchanged directional algorithm chain; make fund-raising data transparent through on-chain public archives; eliminate charitable organizations which are separate and unreliable to replace them with a divisional system – that is unchangeable and dispersible in preventing and stopping the Coronavirus from spreading globally.
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
Contract ownership is not renounced (belongs to a wallet)
Pragma version0.6.8 (#2) allows old versions
solc-0.6.8 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.
