Most central software has good documentation. Some of the smaller code is not documented, but most has descriptions of the functions and variables described in a clear and consistent manner. Overall and 80% score.
8. Is it possible to trace the documented software to its implementation in the protocol's source code? (%)
60% Clear association between code and documents via non explicit traceability
9. Is the documentation organized to ensure information availability and clarity? (%)
Document organization is excellent.
This section covers the testing process of the protocol’s smart contract code previous to its deployment on the mainnet. The document explaining these questions is here.
10. Has the protocol tested their deployed code? (%)
Test to Code = 27379 / 16422 = 166% which gives a 100% score ─────────────────────────────────────────────────────────────────────────────── Language Files Lines Blanks Comments Code Complexity ─────────────────────────────────────────────────────────────────────────────── JavaScript 60 16422 2467 3926 10029 1148 ─────────────────────────────────────────────────────────────────────────────── Total 60 16422 2467 3926 10029 1148 ─────────────────────────────────────────────────────────────────────────────── Estimated Cost to Develop $304,029 Estimated Schedule Effort 8.748268 months Estimated People Required 3.087519 ─────────────────────────────────────────────────────────────────────────────── Processed 592925 bytes, 0.593 megabytes (SI) ─────────────────────────────────────────────────────────────────────────────── C:\Users\User\Sync\DeFiSafety\DeFiSafety Common\Products\Processs Quality Reviews\Reviews\0.9\PancakeSwap\Flattened>cd C:\Users\User\Sync\DeFiSafety\DeFiSafety Common\Products\Processs Quality Reviews\Reviews\0.9\PancakeSwap\TestingEnv C:\Users\User\Sync\DeFiSafety\DeFiSafety Common\Products\Processs Quality Reviews\Reviews\0.9\PancakeSwap\TestingEnv>scc.exe ─────────────────────────────────────────────────────────────────────────────── Language Files Lines Blanks Comments Code Complexity ─────────────────────────────────────────────────────────────────────────────── TypeScript 30 18648 3440 1106 14102 80 JSON 16 6596 0 0 6596 0 JavaScript 14 2094 314 426 1354 145 YAML 1 41 9 0 32 0 ─────────────────────────────────────────────────────────────────────────────── Total 61 27379 3763 1532 22084 225 ─────────────────────────────────────────────────────────────────────────────── Estimated Cost to Develop $696,429 Estimated Schedule Effort 11.986911 months Estimated People Required 5.161615 ─────────────────────────────────────────────────────────────────────────────── Processed 899435 bytes, 0.899 megabytes (SI) ───────────────────────────────────────────────────────────────────────────────
11. How covered is the protocol's code? (%)
No code coverage found, but a good set of tests so 50%.
12. Is there a detailed report of the protocol's test results?(%)
No test report found.
13. Has the protocol undergone Formal Verification? (Y/N)
No evidence of formal verification is found.
This section looks at the 3rd party software audits done. It is explained in this document.
14. Is the protocol sufficiently audited? (%)
The protocol has undergone multiple audits before being deployed. These audits were conducted by reputable third-party security firms such as Peckshield, Slowmist, OtterSec, and Halborn. The audit reports are public and cover various aspects of the protocol including Lottery V2, PancakeSwap Factory and Router, Aptos PancakeSwap MasterChef, Aptos PancakeSwap Syrup Pool, and Aptos PancakeSwap DEX. There is no mention of any required changes that were not implemented, indicating high-quality, secure code.
15. Is there a matrix of audit applicability on deployed code (%)? Please refer to the example doc for reference.
The list of audits clearly indicates the context end date for each audit. As the software is immutable it implies that all of the audits are relevant. For this reason will give a score of 70%.
16. Is the bug bounty value acceptably high (%)
The bug bounty program is run by Pancakeswap itself. It has a respectable $1 million maximum. As per our guidance, this gives a score of 80%.
17. Is there documented protocol monitoring (%)?
No protocol monitoring documentation was found.
18. Is there documented protocol front-end monitoring (%)?
The document mentions the use of Cloudflare for email protection on the website. This can be considered as a measure for DDOS protection, thus fulfilling one of the four elements mentioned in the research instructions. However, there is no clear mention about DNS steps to protect the domain, Intrusion detection protection on the front end, or Unwanted front-end modification detection in the provided documents.

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.
19. Is the protocol code immutable or upgradeable? (%)
The code appears immutable.
20. Is the protocol's code upgradeability clearly explained in non technical terms? (%)
The protocol's documentation does not provide information on the upgradeability of its code in nontechnical terms. There is no mention of either immutable or upgradeable smart contracts, or any clear explanation that details the safety of user investments. Therefore 50% as per guidance.
21. Are the admin addresses, roles and capabilities clearly explained? (%)
The provided documentation does not contain any detailed references or explanations regarding admin addresses, roles, or permissions present in the smart contracts. As such, it is not possible to gauge the level of control and potential influence these entities have over the protocol.
22. Are the signers of the admin addresses clearly listed and provably distinct humans? (%)
The documentation of the protocol does mention the admin addresses and the signer of the resources account. However, it does not provide any evidence or arguments to verify that these signers are distinct individuals.
23. Is there a robust documented transaction signing policy? Please refer to the Example doc for reference.(%)
There is no evident transaction signing policy in the provided documentation. The documents do not mention any specific transaction signing policy or any of the elements listed in the research instructions.
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. These questions are explained in this document.
24. Are Oracles relevant? (Y/N)
Oracles are used in the prediction market.
25. Is the protocol's Oracle sufficiently documented? (%)
75% The Oracle documentation identifies both source and timeframe but does not provide additional context regarding smart contracts.
26. Can flashloan attacks be applied to the protocol, and if so, are those flashloan attack risks mitigated? (Y/N)
There is an answer in the FAQ that covers flash loan attacks.
