Volta Meta is a community based project, where the Liquidity Pools of VMETA token with other tokens are managed by the collective wisdom.
Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)
VoltaMeta.totalSupply (#70) shadows:
- ERC20Basic.totalSupply (#44)
Remove the state variable shadowing.

Pragma version^0.4.26 (#1) allows old versions
solc-0.4.26 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.

- balances[_to] = balances[_to].add(_amount) (#120)
- distributionFinished = true (#184)
- distr(msg.sender,airTokens) (#189)
