report
Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

Bison._writeCheckpoint(address,uint32,uint96,uint96) (contracts/governance/Bison.sol#390-412) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/governance/Bison.sol#402-403)
Don't use strict equality to determine if an account has enough Ether or tokens.

Bison.constructor(address,address,uint256).minter_ (contracts/governance/Bison.sol#85) lacks a zero-check on :
- minter = minter_ (contracts/governance/Bison.sol#92)
Bison.setMinter(address).minter_ (contracts/governance/Bison.sol#101) lacks a zero-check on :
- minter = minter_ (contracts/governance/Bison.sol#104)
Check that the address is not zero.

Bison.constructor(address,address,uint256) (contracts/governance/Bison.sol#85-95) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(mintingAllowedAfter_ >= block.timestamp,bison::constructor: minting can only begin after deployment) (contracts/governance/Bison.sol#86-89)
Bison.mint(address,uint256) (contracts/governance/Bison.sol#112-131) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp >= mintingAllowedAfter,Bison::mint: minting not allowed yet) (contracts/governance/Bison.sol#114)
Bison.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (contracts/governance/Bison.sol#155-200) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= deadline,Bison::permit: signature expired) (contracts/governance/Bison.sol#195)
Bison.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/governance/Bison.sol#244-271) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,Bison::delegateBySig: signature expired) (contracts/governance/Bison.sol#269)
Avoid relying on block.timestamp.

- ^0.6.0 (contracts/governance/Bison.sol#2)
- ABIEncoderV2 (contracts/governance/Bison.sol#3)
Use one Solidity version.

Pragma version>=0.6.0<0.8.0 (@openzeppelin/contracts/math/SafeMath.sol#3) is too complex
Pragma version^0.6.0 (contracts/governance/Bison.sol#2) allows old versions
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.
