Morpho is an immutable overcollateralized lending protocol with permissionless market creation. It implements independent lending markets, which are simple lending pools with only one collateral asset and one borrowable asset, priced through an oracle. The interest rate is given by an immutable interest rate model (IRM). Each pool is characterized by a predefined Liquidation Loan-to-Value (LLTV).

Permanent freezing of unclaimed yield

Temporary freezing of funds

Injecting/modifying the static content on the target application without JavaScript (persistent), such as:  HTML injection without JavaScript, Replacing existing text with arbitrary text, Arbitrary file uploads, etc

Changing sensitive details of other users (including modifying browser local storage) without already-connected wallet interaction and with up to one click of user interaction, such as:  Email, Password of the victim etc.

Improperly disclosing confidential user information, such as:  Email address, Phone number, Physical address, etc.

Subdomain takeover without already-connected wallet interaction

Manipulation of governance voting result deviating from voted outcome and resulting in a direct change from intended effect of original results

Morpho Documentation

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.3](https://immunefi.com/immunefi-vulnerability-severity-classification-system-v2-3/). 

__Reward Calculation for Critical Level Reports__

For critical smart contract bugs on Morpho smart contracts solely, the reward amount is 10% of the funds directly affected up to a maximum of USD 2 500 000. The calculation of the amount of funds at risk is based on the time and date the bug report is submitted. However, a minimum reward of USD 250 000 is to be rewarded in order to incentivize security researchers against withholding a critical bug report.

For critical smart contract bugs on Morpho Vaults and other Morpho periphery smart contracts, the reward amount is 10% of the funds directly affected up to a maximum of USD 1 500 000. The calculation of the amount of funds at risk is based on the time and date the bug report is submitted. However, a minimum reward of USD 150 000 is to be rewarded in order to incentivize security researchers against withholding a critical bug report.

For critical smart contract bugs on Morpho’s Optimizer contracts, the reward amount is 10% of the funds directly affected up to a maximum of USD 555 555. The calculation of the amount of funds at risk is based on the time and date the bug report is submitted. However, a minimum reward of USD 55 000 is to be rewarded in order to incentivize security researchers against withholding a critical bug report.

__Repeatable Attack Limitations__

- If the smart contract where the vulnerability exists can be upgraded or paused, only the initial attack will be considered for a reward. This is because the project can mitigate the risk of further exploitation by upgrading or pausing the component where the vulnerability exists. The reward amount will depend on the severity of the impact and the funds at risk.
- For critical repeatable attacks on smart contracts that cannot be upgraded or paused, the project will consider the cumulative impact of the repeatable attacks for a reward. 

This is because the project cannot prevent the attacker from repeatedly exploiting the vulnerability until all funds are drained and/or other irreversible damage is done. Therefore, this warrants a reward equivalent to 10% of funds at risk, capped at the maximum critical reward. 

__Reward Calculation for High Level Reports__

- High vulnerabilities concerning theft/permanent freezing of unclaimed yield/royalties are rewarded within a range of USD 10 000 to USD 50 000 depending on the funds at risk, capped at the maximum high reward.  
- In the event of temporary freezing, the reward doubles from the full frozen value for every additional [24h] that the funds are temporarily frozen, up until a max cap of the high reward. This is because as the duration of the freezing lengthens, the potential for greater damage and subsequent reputational harm intensifies. Thus, by increasing the reward proportionally with the frozen duration, the project ensures stronger incentives for bug disclosure of this nature.

For critical web/apps bug reports will be rewarded with USD 50 000, only if the impact leads to:

- A loss of funds involving an attack that does not require any user action
- Private key or private key generation leakage leading to unauthorized access to user funds 

All other impacts that would be classified as Critical would be rewarded a flat amount of USD 10 000. The rest of the severity levels are paid out according to the Impact in Scope table.  

__Reward Payment Terms__

Payouts are handled by the Morpho team directly and are denominated in USD. However, payments are done in USDC on Ethereum.

The calculation of the net amount rewarded is based on the average price between CoinMarketCap.com and CoinGecko.com at the time the bug report was submitted. No adjustments are made based on liquidity availability.
