white paper

Cyclone is a multi-chain, non-custodial, privacy-preserving protocol. Cyclone applies zkSNARKs to enable transactional privacy by breaking the on-chain link between depositor and recipient addresses. It uses a smart contract that accepts coins/tokens deposits, which can be withdrawn by a different address. Whenever an asset is withdrawn from Cyclone, there is no way to link the withdrawal to the deposit for absolute privacy.

Token seems to be (relatively) fine. It still become a scam, but probability is moderate.



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

CycloneToken._writeCheckpoint(address,uint32,uint256,uint256) (#756-767) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#759)
Don't use strict equality to determine if an account has enough Ether or tokens.

CycloneToken.updateOperator(address) (#544-547) should emit an event for:
- operator = _operator (#546)
Emit an event for critical parameter changes.

ShadowToken.constructor(address,address,string,string,uint8)._coToken (#468) lacks a zero-check on :
- coToken = _coToken (#470)
Check that the address is not zero.

CycloneToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (#655-664) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,delegateBySig: signature expired) (#662)
Avoid relying on block.timestamp.

CycloneToken.onlyMinters() (#512-515) compares to a boolean constant:
-require(bool,string)(minters[msg.sender] == true,not the minter) (#513)
Remove the equality to the boolean constant.

SafeMath.mul(uint256,uint256) (#75-82) is never used and should be removed
Remove unused functions.

Pragma version<0.6>=0.4.24 (#498) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Parameter CycloneToken.burn(uint256)._amount (#561) is not in mixedCase
Follow the Solidity naming convention.

CycloneToken.constructor(address,address) (#523-532) uses literals with too many digits:
- _moveDelegates(address(0),delegates[_lp],2021 * 100000000000000000) (#529)
Use: Ether suffix, Time suffix, or The scientific notation

getPriorVotes(address,uint256) should be declared external:
- CycloneToken.getPriorVotes(address,uint256) (#683-715)
Use the external attribute for functions never called from the contract.
