Chain Wars is a brand new Digital Collectible Card Game (DCCG). Its experience is amplified by ‘Play to Earn’ and supportive products. It implements the most exciting, innovative features blockchain technology has to offer right now. The game is driven by blockchain technology and runs on multiple chains. This allows for a fresh approach to create a game. The main opportunities within this fresh approach are decentralizing a game and powering it by its own currency, Chain Wars Essence (CWE). Each chain correlates to a playable race within the game. The current races involve Origon, Nimble and Human. The majority of items are player-owned and tradeable via our own Marketplace. So, are you ready to create your best possible deck and compete with other players? We hope to see you on board!

ERC20Votes._writeCheckpoint(ERC20Votes.Checkpoint[],function(uint256,uint256) returns(uint256),uint256) (contracts/abstracts/ERC20Votes.sol#236-250) uses a dangerous strict equality:
- pos > 0 && ckpts[pos - 1].fromBlock == block.number (contracts/abstracts/ERC20Votes.sol#245)
Don't use strict equality to determine if an account has enough Ether or tokens.

ERC20Votes._moveVotingPower(address,address,uint256).oldWeight_scope_0 (contracts/abstracts/ERC20Votes.sol#230) is a local variable never initialized
ERC20Votes._moveVotingPower(address,address,uint256).newWeight_scope_1 (contracts/abstracts/ERC20Votes.sol#230) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

ERC20Permit.constructor(string).name (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#35) shadows:
- ERC20.name() (@openzeppelin/contracts/token/ERC20/ERC20.sol#61-63) (function)
- IERC20Metadata.name() (@openzeppelin/contracts/token/ERC20/extensions/IERC20Metadata.sol#16) (function)
Rename the local variables that shadow another component.

Variable 'ERC20Votes._moveVotingPower(address,address,uint256).newWeight (contracts/abstracts/ERC20Votes.sol#225)' in ERC20Votes._moveVotingPower(address,address,uint256) (contracts/abstracts/ERC20Votes.sol#218-234) potentially used before declaration: (oldWeight,newWeight) = _writeCheckpoint(_checkpoints[dst],_add,amount) (contracts/abstracts/ERC20Votes.sol#230)
Variable 'ERC20Votes._moveVotingPower(address,address,uint256).oldWeight (contracts/abstracts/ERC20Votes.sol#225)' in ERC20Votes._moveVotingPower(address,address,uint256) (contracts/abstracts/ERC20Votes.sol#218-234) potentially used before declaration: (oldWeight,newWeight) = _writeCheckpoint(_checkpoints[dst],_add,amount) (contracts/abstracts/ERC20Votes.sol#230)
Move all variable declarations prior to any usage of the variable, and ensure that reaching a variable declaration does not depend on some conditional if it is used unconditionally.

ERC20Permit.permit(address,address,uint256,uint256,uint8,bytes32,bytes32) (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#40-59) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (@openzeppelin/contracts/token/ERC20/extensions/draft-ERC20Permit.sol#49)
ERC20Votes.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/abstracts/ERC20Votes.sol#143-160) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,ERC20Votes: signature expired) (contracts/abstracts/ERC20Votes.sol#151)
Avoid relying on block.timestamp.
