Arkham
Arkham is a crypto intelligence platform that enables users to see the organizations and people behind crypto wallet addresses & learn about their activities.
PoC required
Rewards by Threat Level
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 Web/App bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD 20 000. 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
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.
Public Disclosure of Known Issues
Bug reports covering previously-discovered bugs acknowledged below are not eligible for any reward through the bug bounty program.
- Old referral links exposing user emails
- User can share their private entities and dashboards by sharing the URL (this is a feature not a bug)
Previous Audits
Arkham 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:
- Web/App - Critical
- Web/App - High
- Web/App - Medium
- Web/App - 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.
Reward Payment Terms
Payouts are handled by the Arkham team directly and are denominated in USD. However, payments are done in ARKM.
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.

Responsible Publication
Arkham 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
Arkham adheres to the Primacy of Impact for the following severity levels:
- Web/App - Critical
- Web/App - High
- Web/App - Medium
Arkham adheres to the Primacy of Impact for the following impacts:
- Web/App - Low - Temporarily disabling user to access target site
If an impact 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. 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 impacts are considered under the Primacy of Rules, which means that they are bound by the terms of the bug bounty program.
Known Issue Assurance
Arkham commits to providing Known Issue Assurance to bug submissions through their program. This means that Arkham 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
Arkham has satisfied the requirements for the Immunefi Standard Badge, which is given to projects that adhere to our best practices.
KYC not required
No KYC information is required for payout processing.
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.
