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

DefilyToken._writeCheckpoint(address,uint32,uint256,uint256) (#1059-1077) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1069)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract ownership is not renounced (belongs to a wallet)

Redundant expression "this (#31)" inContext (#25-34)
Remove redundant statements if they congest code but offer no value.

DefilyToken.manualMintLimit (#688) should be constant
Add the constant attributes to state variables that never change.

DefilyToken.getChainId() (#1084-1088) uses assembly
- INLINE ASM (#1086)
Do not use evm assembly.

DefilyToken.capUpdate(uint256) (#710-712) should emit an event for:
- _cap = _newCap (#711)
DefilyToken.lockFromUpdate(uint256) (#715-717) should emit an event for:
- lockFromBlock = _newLockFrom (#716)
DefilyToken.lockToUpdate(uint256) (#720-722) should emit an event for:

Emit an event for critical parameter changes.

DefilyToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#925-966) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,DEFILY::delegateBySig: signature expired) (#964)
Avoid relying on block.timestamp.
