BYE Token

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

BYE.dayZero() (#534-536) uses a weak PRNG: "block.timestamp - (block.timestamp % (24 * 3600)) (#535)"
Do not use block.timestamp, now or blockhash as a source of randomness

Additional information: link

BYE.updatePrice() (#488-500) uses a dangerous strict equality:
- nowTime == zero (#491)
Don't use strict equality to determine if an account has enough Ether or tokens.

Ownable.constructor(address)._addr (#182) lacks a zero-check on :
- _owner = _addr (#183)
Check that the address is not zero.

BYE.updatePrice() (#488-500) uses timestamp for comparisons
Dangerous comparisons:
- nowTime == zero (#491)
Avoid relying on block.timestamp.

Pragma version0.8.1 (#6) allows old versions
solc-0.8.1 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.
