Shardeum is an EVM-based, linearly scalable network offering low gas fees forever while maintaining true decentralization and (hopefully) solid security. Shardeum is a large project and as such, will be split over two concurrent boosts. This boost, called Core III, will cover the Web3 aspects of the project. This will cover four components: Shardus Core Protocol, Shardeum Validator Nodes, networking libs, and Crypto-utils. For more information about Shardeum, please visit https://shardeum.org/

Asset Accuracy Assurance
Bugs found on assets incorrectly listed in-scope will be considered valid and be rewarded.
Private Known Issues Reward Policy
Private known issues, meaning known issues that were not publicly disclosed, are valid for a reward equal to that of a bug one severity lower.
Known Issue Assurance
Shardeum commits to providing Known Issue Assurance to bug submissions through their program. This means that Shardeum will either disclose known issues publicly, or at the very least, privately via a self-reported bug submission.
In a potential scenario of a mediation, this allows for a more objective and streamlined process, in order to prove that an issue is known. Otherwise, assuming the bug report is valid, it would result in the report being considered as in-scope, and due a reward.
Primacy of Impact vs Primacy of Rules
Shardeum adheres to the Primacy of Rules for all impacts. Which means that the whole bug bounty program is run strictly under the terms and conditions stated within this page.
Eligibility Criteria
Security researchers who wish to participate must adhere to the rules of engagement set forth in this program and cannot be:
- On OFACs SDN list
- Official contributor, both past or present
- Employees and/or individuals closely associated with the project
- Security auditors that directly or indirectly participated in the audit review
Responsible Publication
Whitehats may publish their bug reports after they have been fixed & paid, or closed as invalid, with the following exceptions:
- Bug reports in mediation may not be published until mediation has concluded and the bug report is resolved.
Immunefi may publish bug reports submitted to this audit competition and a leaderboard of the participants and their earnings.
Feasibility Limitations
The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.
Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
Immunefi Standard Badge
By adhering to Immunefi’s best practice recommendations, Shardeum has satisfied the requirements for the Immunefi Standard Badge.
