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

ERC20Votes._writeCheckpoint(ERC20Votes.Checkpoint[],function(uint256,uint256) returns(uint256),uint256) (#2234-2248) uses a dangerous strict equality:
- pos > 0 && ckpts[pos - 1].fromBlock == block.number (#2243)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract name (OSSDAO on BSC OSSDAO.ORG) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

ERC20Votes._moveVotingPower(address,address,uint256).oldWeight_scope_0 (#2228) is a local variable never initialized
ERC20Votes._moveVotingPower(address,address,uint256).newWeight_scope_1 (#2228) 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 (#1944) shadows:
- ERC20.name() (#1612-1614) (function)
- IERC20Metadata.name() (#1537) (function)
Rename the local variables that shadow another component.

OSSOnBSC.setSinger(address).signer (#2542) lacks a zero-check on :
- _cSigner = signer (#2543)
Check that the address is not zero.

Variable 'ECDSA.tryRecover(bytes32,bytes).r (#527)' in ECDSA.tryRecover(bytes32,bytes) (#522-551) potentially used before declaration: r = mload(uint256)(signature + 0x20) (#544)
Variable 'ERC20Votes._moveVotingPower(address,address,uint256).newWeight (#2223)' in ERC20Votes._moveVotingPower(address,address,uint256) (#2216-2232) potentially used before declaration: (oldWeight,newWeight) = _writeCheckpoint(_checkpoints[dst],_add,amount) (#2228)
Variable 'ERC20Votes._moveVotingPower(address,address,uint256).oldWeight (#2223)' in ERC20Votes._moveVotingPower(address,address,uint256) (#2216-2232) potentially used before declaration: (oldWeight,newWeight) = _writeCheckpoint(_checkpoints[dst],_add,amount) (#2228)
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) (#1949-1968) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= deadline,ERC20Permit: expired deadline) (#1958)
ERC20Votes.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#2141-2158) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,ERC20Votes: signature expired) (#2149)
Avoid relying on block.timestamp.
