Rewards by Threat Level
Please review how rewards are distributed based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale system with separate scales for Smart Contracts and Websites/Apps.
Payouts and Payout Requirements:
Payouts are handled by the Horizen Labs team directly and are denominated in USD. However, payouts can be done in ZEN. Horizen Labs commits to honoring payouts according to the terms set out in this program at the time of report submission, and to treat this program as the agreement and source of truth concerning bug reports and responsible disclosures.
For the purposes of determining report validity, this is a Primacy of Impact program.
Learn more about report validity best practices here: Best Practice - Primacy of Impact vs Primacy of Rules.
Unlike other bug bounty programs on Immunefi, all bug report submissions, including associated vulnerabilities, become the exclusive property of Horizen. By making a submission to this program and in consideration for a bounty, the bug submitter conveys all ownership rights, titles, and interests in the bug report to Horizen. Thus, the final decision on whether a postmortem will be written is at the sole discretion of Horizen
KYC Requirements:
Horizen Labs does have a Know Your Customer (KYC) requirement for bug bounty payouts.
KYC Info Required:
Name, address, ID/passport, and a proof of residency
KYC information is only required on confirmation of the validity of a bug report.

Prohibited Activities
- Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
- Any testing with pricing oracles or third-party smart contracts
- Attempting phishing or other social engineering attacks against our employees and/or customers
- Any testing with third-party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
- Any denial of service attacks that are executed against project assets
- Automated testing of services that generates significant amounts of traffic
- Public disclosure of an unpatched vulnerability in an embargoed bounty
- Any other actions prohibited by the Immunefi Rules
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.
