All smart contracts of Nomad can be found at [https://github.com/nomad-xyz/monorepo/](https://github.com/nomad-xyz/monorepo/).  However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

Nomad is a security-first cross-chain messaging protocol that enables seamless communication between blockchains. By leveraging an optimistic mechanism, Nomad only requires one honest actor to keep the entire system safe. This drastically reduces the trust required relative to other interoperability solutions.

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

Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield

Permanent freezing of funds

Protocol insolvency

Temporary freezing of funds

Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.

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/). 

For critical Blockchain/DLT bugs, the reward will be determined based on the funds at risk, and may also consider subsequent impacts on other projects built on the respective blockchain, as well as PR and brand reputation risk, capped at the maximum critical reward. 

To incentivize security researchers and ensure bug reports are not withheld, a minimum reward __USD 10 000__ will be provided. 

For critical smart contract bugs, the reward amount is __10%__ of the funds directly affected up to a maximum of __USD 100 000__. 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 10 000__ is to be rewarded in order to incentivize security researchers against withholding a bug report.

__Repeatable Attack Limitations__

  - If the smart contract where the vulnerability exists can be upgraded or paused, only the initial attacks within the first hour 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 can not 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__

  - In the event of temporary freezing, the reward increases at a multiplier of two 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 lenghents, 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.    

__Reward Payment Terms__

Payouts are handled by the __Nomad__ team directly and are denominated in __USD__. However, payouts are done in __USDC__.

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.
