Rewards by Threat Level

Smart Contract
USD $50,000 to USD $1,000,000
USD $30,000
USD $10,000
USD $1,500

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

Reward Calculation for Critical Level Reports

For critical Smart Contract bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD 1 000 000. 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 50 000 is to be rewarded in order to incentivize security researchers against withholding a bug report.
Repeatable Attack Limitations

In cases of repeatable attacks for smart contract bugs, only the first attack will be counted, regardless of whether the smart contract is upgradable, pausable, or killable.

Restrictions on Security Researcher Eligibility

Security researchers who fall under any of the following are ineligible for a reward

  • Residents or citizens of OFAC restricted countries as well as citizens or residents individually listed on the EU sanctions map
  • Members of a household, related to or next of kin of a compensated core team members of the SSV DAO.

Previous Audits 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:

  • Smart Contract - Critical
  • Smart Contract - High
  • Smart Contract - Medium
  • Smart Contract - Low

All PoCs submitted must comply with the Immunefi-wide 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

  • Disclosure of vulnerabilities will require the approval of the SSV DAO Grants committee
  • Payments for approved reports will be sent on the first half of the month following the report approval
  • Up to 150 000 SSV token are available as a total reward pool for this BBP

Reward Payment Terms

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

The calculation of the net amount rewarded is based on the average price between and 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.

Program Overview

The is a fully decentralized, open-source, and trustless DVT Network that provides a reusable infrastructure solution for decentralizing Ethereum validators.

The protocol supports Ethereum’s validation layer by distributing validator operations to the network’s multiple non-trusting nodes (a.k.a Operators). Clusters of operator nodes operate validators on behalf of the staker and simultaneously help solve the fundamental issues of centralization, redundancy, and security that exist within Ethereum’s PoS consensus.

KYC Requirement

The provision of KYC is required to receive a reward for this bug bounty program where the following information will be required to be provided:

  • Official government identification document (Passport, ID Card) of the bounty’s recipient
  • Up to date proof of address document (utility bill, Bank statement etc)

KYC information is only required on confirmation of the validity of a bug report.

Responsible Publication adheres to category 3: Approval Required. This Policy determines what information whitehats are allowed to make public from their submitted bug reports. For more information about the category selected, please refer to our Responsible Publication page.

Primacy of Impact vs Primacy of Rules adheres to the Primacy of Impact for the following severity levels:

  • Smart Contract - Critical
  • Smart Contract - High
  • Smart Contract - Medium
  • Smart Contract - Low

If a category’s severity level is covered within the Primacy of Impact, it means that even if the impacted asset is not in-scope but is owned by the project, then it would be considered as in-scope of the bug bounty program as long as it involves an impact under that respective severity level. When submitting a report, just select the Primacy of Impact asset placeholder. If the team behind this project has multiple projects, those other projects are not covered under the Primacy of Impact of this program. Instead, check if those other projects have a bug bounty program on Immunefi.

Testnet and mock files are not covered under the Primacy of Impact.

All other severity levels not listed here are considered under the Primacy of Rules, which means that they are bound by the terms of the bug bounty program.

Known Issue Assurance commits to providing Known Issue Assurance to bug submissions through their program. This means that will either disclose known issues publicly or at the very least privately via a self-reported bug submission in order to allow for a more objective and streamlined mediation process to prove that an issue is known. Otherwise, assuming the bug report itself is valid, it would result in the bug report being considered in-scope and due 100% of the reward with respect to the bug bounty program terms.

Immunefi Standard Badge has satisfied the requirements for the Immunefi Standard Badge, which is given to projects that adhere to our best practices.

KYC required

The submission of KYC information is a requirement for payout processing.

Prohibited Activities

Default 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.
