Coreum addresses the existing limitations of the current blockchains and empowers a solid foundation for future decentralized projects. Coreum’s unique approach is to provide built-in, on-chain solutions to process transactions in a deterministic way to ensure a fast, secure, cheap, and green network for various use cases.

Network not being able to confirm new transactions (Total network shutdown)

Direct loss of funds

Permanent freezing of funds (fix requires hard fork)

Temporary freezing of network transactions by delaying one block by 500% or more of the average block time of the preceding 24 hours beyond standard difficulty adjustments

Causing network processing nodes to process transactions from the mempool beyond set parameters

RPC API crash affecting projects with greater than or equal to 25% of the market capitalization on top of the respective layer

Increasing network processing node resource consumption by at least 30% without brute force actions, compared to the preceding 24 hours

Shutdown of greater than or equal to 30% of network processing nodes without brute force actions, but does not shut down the network

Shutdown of greater than 10% or equal to but less than 30% of network processing nodes without brute force actions, but does not shut down the network

Modification of transaction fees outside of design parameters

Rewards are distributed according to the impact the vulnerability could otherwise cause based on the Impacts in Scope table further below. 

For critical Blockchain/DLT bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD 25 000, but 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 USD 25 000. 

To incentivize security researchers and ensure bug reports are not withheld, a minimum reward USD 3 000  will be provided. 

For Total Network Shutdown, the maximum payment of 25 000 will be rewarded.

__Repeatable Attack Limitations__

If the blockchain/DLT component where the vulnerability exists can be upgraded/paused/killed, 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, pausing, or in some cases, killing the component where the vulnerability exists. The reward amount will depend on the severity of the impact and the funds at risk. 

All other impacts that would be classified as Critical would be rewarded a flat amount of USD 3 000. The rest of the severity levels are paid out according to the Impact in Scope table.  

__Public Disclosure of Known Issues__

Bug reports covering previously-discovered bugs acknowledged below are not eligible for any reward through the bug bounty program. 
- Previously known vulnerabilities in Tendermint(CometBFT) and or/any other fork of these. 
- Previously known vulnerabilities in Cosmos-SDK and or/any other fork of these. 
- Previously known vulnerabilities in CosmWasm and or/any other fork of these. 
- Previously known vulnerabilities in IBC and or/any other fork of these. 
- Any other vulnerabilities that come from Third-Party services and SDKs. 
- Public Zero-day vulnerabilities
- Any issue on the issue tracker: [https://github.com/CoreumFoundation/coreum/issues ](https://github.com/CoreumFoundation/coreum/issues)
- Any issue found on open pull requests: [https://github.com/CoreumFoundation/coreum/pulls ](https://github.com/CoreumFoundation/coreum/pulls)
   - The bridge is out of scope - Coreum to XRPL and XRPL to Coreum

__Previous Audits__

Coreum has provided these completed audit review reports for reference. Any unfixed vulnerability mentioned in these reports are not eligible for a reward.

__Proof of Concept (PoC) Requirements__

A PoC is required for the following severity levels:
- Blockchain/DLT - Critical
- Blockchain/DLT - High
- Blockchain/DLT - Medium
- Blockchain/DLT - Low

All PoCs submitted must comply with the Immunefi-wide [PoC Guidelines and Rules.](https://immunefisupport.zendesk.com/hc/en-us/articles/9946217628561-Proof-of-Concept-PoC-Guidelines-and-Rules) Bug report submissions without a PoC when a PoC is required will not be provided with a reward.

__Other Terms and Information__

Payouts are handled by the Coreum team directly and are denominated in USD. However, payouts are done in COREUM. This bug bounty program will have a hard cap of USD 500 000. In the event that multiple bug reports are submitted that exceed this amount, the rewards will be provided on a first come first served basis.

__Reward Payment Terms__

Payouts are handled by the Coreum team directly and are denominated in USD. However, payments are done in COREUM.

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. For avoidance of doubt, if the reward amount is USD 5 000 and the average price is USD 1.75 per token, then the reward will be 2857.142857 units of that token.
