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

Admin Controls

93%

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.

Answer: 100%

This protocol has good timelock documentation which can be found at this location, section 4.

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.

25. Is the Timelock of an adequate length? (Y/N)

Answer: 100%

The timelock is of a 24 hour length, as specified in this location., Section 4. However this is a requirement due to their close association with Compound and AAVE. Their timelock must be less than the shortest of those two. For this reason a 100% score is given.

Percentage Score Guidance:

100%

Timelock is between 48 hours to 1 week OR justification as to why no Timelock is needed / is outside this length.

Oracles

100%

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.

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

Answer: 100

The protocol's oracle source is clearly indicated as identical to that of AAVE and Compound, as this uses the same code. This is explained in the Risk section the Liquidation and Price Oracles sections. As the Oracle sections for both Compound and AAVE are 100%, we will extend the same score to Morpho.

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.

No oracle is named / no oracle information is documented.

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

Answer: Yes

This protocol takes credit from the AAVE and Compound Oracles, both of which answer this question. Therefore a yes is extended.

Score Guidance:

Yes

The protocol cannot be front run and there is an explanation as to why OR documented front running countermeasures are implemented.

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

This protocol takes credit from the AAVE and Compound Oracles, both of which answer this question. Therefore a yes is extended.

Score Guidance:

Yes

The protocol's documentation includes information on how they mitigate the possibilities and extents of flash loan attacks.

The protocol's documentation does not include any information regarding the mitigation of flash loan attacks.
