There is no zero-check on the input parameters when creating the contract Beebots. If any of them (_alpha, _beta, or _beneficiary) is provided as 0x0 accidentally, the contract has to be redeployed. Besides, losing funds is possible when minting tokens if _beneficiary is set to 0 (see line 387).

Impact
There is no zero-check on the input parameters when creating the contract
Beebots. If any of them (_alpha,_beta, or_beneficiary) is provided as 0x0 accidentally, the contract has to be redeployed. Besides, losing funds is possible when minting tokens if_beneficiaryis set to 0 (see line 387).Proof of Concept

Recommended Mitigation Steps
Add three zero-checks in the
constructor(e.g.,require(beta != address(0))) with proper error messages.
