META [METACOINCAP] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Token is flagged by TokenSniffer due to presence of exploit in contract code

Metacoincap.claimStuckTokens(address) (#187-191) ignores return value by erc20token.transfer(owner,balance) (#190)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract ownership is not renounced (belongs to a wallet)

Pragma version>=0.5.10 (#1) allows old versions
solc-0.5.10 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.
