Annex Finance is a lending/borrowing platform for cryptocurrencies, the project's goal is to bridge the traditional lending platform for BSC, ETH, and Poly network bringing the network closer to each other, we will release BSC first, then eth and poly to follow after

Annex Finance will also be providing DEX swap allowing users to create LP and liquidity itself to mint high apy returns and increase ANN price/volume while allowing users to borrow and supply assets through smart contracts, on top of lending/borrowing, we will also be offering NFT marketplace as well as IDO auction, basically a one stop shop defi platform for multichain network

ANN (#112-693) contract sets array length with a user-controlled value:
- epochConfigs.push(newEC) (#387)
ANN (#112-693) contract sets array length with a user-controlled value:
- epochConfigs.push(newEpochConfig) (#211)
Do not allow array lengths to be set directly set; instead, opt to add values as needed. Otherwise, thoroughly review the contract to ensure a user-controlled variable cannot reach an array length assignment.

ANN._writeCheckpoint(address,uint32,uint96,uint96) (#608-619) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#611)
ANN.getEpochs(uint256) (#444-466) uses a dangerous strict equality:
- blocks == 0 (#458)
ANN.getHoldingReward(address) (#473-552) uses a dangerous strict equality:
- lastEpoch == 0 (#482)
ANN.getHoldingReward(address) (#473-552) uses a dangerous strict equality:
- tp.epoch == lastEligibleEpoch (#506)
ANN.setEpochConfig(uint32,uint32) (#377-390) uses a dangerous strict equality:
- prevEC.epoch == newEC.epoch (#384)
Don't use strict equality to determine if an account has enough Ether or tokens.

Ownable.authorizeOwnershipTransfer(address).authorizedAddress (#82) lacks a zero-check on :
- _authorizedNewOwner = authorizedAddress (#83)
Check that the address is not zero.

ANN.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#310-319) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,ANN::delegateBySig: signature expired) (#317)
Avoid relying on block.timestamp.

ANN.getChainId() (#687-691) uses assembly
- INLINE ASM (#689)
Do not use evm assembly.

Additional information: link

ANN.add32(uint32,uint32,string) (#660-664) is never used and should be removed
Context._msgData() (#23-26) is never used and should be removed
Remove unused functions.

Additional information: link

Constant ANN.totalSupply (#123) is not in UPPER_CASE_WITH_UNDERSCORES
Constant ANN.eligibleEpochs (#126) is not in UPPER_CASE_WITH_UNDERSCORES
Follow the Solidity naming convention.

Redundant expression "this (#24)" inContext (#14-27)
Remove redundant statements if they congest code but offer no value.

Additional information: link

Variable ANN.getHoldingReward(address).nTransferPoint (#475) is too similar to ANN.transferPoints (#160)
Prevent variables from having similar names.

Additional information: link

ANN.slitherConstructorConstantVariables() (#112-693) uses literals with too many digits:
- totalSupply = 1000000000e18 (#123)
Use: Ether suffix, Time suffix, or The scientific notation
