SFLOKIV2 [ShinFlokiV2] Token

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

ShinFlokiV2.pendingRewards(address,uint256) (#1218-1231) uses a dangerous strict equality:
- info.lastHarvestBlock < contractCreationBlock || info.currentlyStaked == false (#1221)
Don't use strict equality to determine if an account has enough Ether or tokens.

Additional information: link

ShinFlokiV2.constructor(address,address)._collectionAddress (#1193) lacks a zero-check on :
- collectionAddress = _collectionAddress (#1199)
Check that the address is not zero.
