Security Incidents

Date:10 Jun 2022
Details: TraderJoe appears to have suffered a smart contract exploit that has diverted $1m from xJoe holders. The team refuses to address the concerns or write a post-mortem. This is not good process. This hack was foreeseable (it happened two years prior to Sushiswap https://twitter.com/YannickCrypto/status/1333027131090227202). The TVL loss is minor. There is no chance of repayment. This puts the penalty at 25%.

Very simply, the audit looks for the following declarations from the developer's site. With these declarations, it is reasonable to trust the smart contracts.

  • Here is my smart contract on the blockchain
  • You can see it matches a software repository used to develop the code
  • Here is the documentation that explains what my smart contract does
  • Here are the tests I ran to verify my smart contract
  • Here are the audit(s) performed to review my code by third party experts

An active program means that a third party (such as Immunefi) is actively driving hackers to the site. An inactive program would be static mentions on the docs.

Admin Controls

0%

This section covers the documentation of special access controls for a DeFi protocol. The admin access controls are the contracts that allow updating contracts or coefficients in the protocol. Since these contracts can allow the protocol admins to "change the rules", complete disclosure of capabilities is vital for user's transparency. It is explained in this document.

18. Is the protocol's admin control information easy to find?

Answer: 0%

There is no admin control information. Although there is a governance section describing future implementation in their docs, the module is currently inactive which makes the detailed information non-quantifiable.

100%
Admin Controls are clearly labelled and on website, docs or repo, quick to find
70%
Admin Controls are clearly labelled and on website, docs or repo but takes a bit of looking

Percentage Score Guidance:
100%
Both the contract documentation and the smart contract code state that the code is not upgradeable or immutable.
80%
All Contracts are clearly labelled as upgradeable (or not)
50%
Code is immutable but not mentioned anywhere in the documentation
0%
Admin control information could not be found

20. Is the type of smart contract ownership clearly indicated? (%)

Answer: 0%

Percentage Score Guidance:
100%
The type of ownership is clearly indicated in their documentation. (OnlyOwner / MultiSig / etc)
50%
The type of ownership is indicated, but only in the code. (OnlyOwner / MultiSig / etc)
0%
Admin Control information could not be found

21. Are the protocol's smart contract change capabilities described? (%)

Answer: 0%

There is no contract change information. Although there is a governance section describing future implementation in their docs, the module is currently inactive which makes the detailed information non-quantifiable.

Percentage Score Guidance:
100%
The documentation covers the capabilities for change for all smart contracts
50%
The documentation covers the capabilities for change in some, but not all contracts
0%
The documentation does not cover the capabilities for change in any contract

22. Is the protocol's admin control information easy to understand? (%)

Description relates to investments safety in clear non-software language
30%
Description all in software-specific language
0%
No admin control information could be found

23. Is there sufficient Pause Control documentation? (%)

Answer: 0%

No pause control information was found. Although there is a governance section describing future implementation in their docs, the module is currently inactive which makes the detailed information non-quantifiable.

Percentage Score Guidance:

If immutable and no changes possible
100%
If admin control is fully via governance
80%
Robust transaction signing process (7 or more elements)
70%
Adequate transaction signing process (5 or more elements)
60%
Weak transaction signing process (3 or more elements)
0%
No transaction signing process evident
Evidence of audits of signers following the process add 20%

24. Is there sufficient Timelock documentation? (%)

Answer: 0%

A timelock with a specific duration and what it applies to is identified, though this applies to just V2. The audit denotes that the current V3 contract does not have a timelock. This means that the timelock documentation is no longer applicable.

Percentage Score Guidance:
100%
Documentation identifies and explains why the protocol does not need a Timelock OR Timelock documentation identifies its duration, which contracts it applies to and justifies this time period.
60%
A Timelock is identified and its duration is specified

A Timelock is identified
0%
No Timelock information was documented

50%
Timelock is less than 48 hours or greater than 1 week.
0%
No Timelock information was documented OR no timelock length was identified.

Oracles

88%

This section goes over the documentation that a protocol may or may not supply about their Oracle usage. Oracles are a fundamental part of DeFi as they are responsible for relaying tons of price data information to thousands of protocols using blockchain technology. Not only are they important for price feeds, but they are also an essential component of transaction verification and security. This is explained in this document.

26. Is the protocol's Oracle sufficiently documented? (%)

Answer: 75

Joe uses Chainlink. It justifies this in this article, but there are no software functions documented.

Score Guidance:
100%
If it uses one, the Oracle is specified. The contracts dependent on the oracle are identified. Basic software functions are identified (if the protocol provides its own price feed data). Timeframe of price feeds are identified. OR The reason as to why the protocol does not use an Oracle is identified and explained.
75%
The Oracle documentation identifies both source and timeframe, but does not provide additional context regarding smart contracts.
50%
Only the Oracle source is identified.
0%
No oracle is named / no oracle information is documented.

27. Is front running mitigated by this protocol? (Y/N)

Answer: Yes

Although no front running countermeasures are identified, their Medium article about their Chainlink Oracle implementation clearly states the mitigation of known exploits.

Score Guidance:
Yes
The protocol cannot be front run and there is an explanation as to why OR documented front running countermeasures are implemented.
No
The Oracle documentation identifies both source and timeframe, but does not provide additional context regarding smart contracts.

28. Can flashloan attacks be applied to the protocol, and if so, are those flashloan attack risks mitigated? (Y/N)

Answer: Yes

Joe identifies it uses Chainlink to prevent flashloan attacks.

Score Guidance:
Yes
The protocol's documentation includes information on how they mitigate the possibilities and extents of flash loan attacks.
No
The protocol's documentation does not include any information regarding the mitigation of flash loan attacks.
