Astar Network

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.

All web/app bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. All High and Critical Blockchain bug reports require a PoC and a suggestion for a fix to be eligible for a reward. All Medium and Low Blockchain bug reports require a suggestion for a fix to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required. In specific cases, we keep the right to ask the whitehat to demonstrate PoC on the test environment provided by the Astar team to validate the impact of the report.

Critical vulnerabilities involving a direct loss of user funds, double spending, or the minting of tokens are capped at 10% of the economic damage, taking primarily into consideration the funds at risk or the amount of tokens that can be minted but also branding and PR considerations, at the discretion of the team. However, there is a minimum reward of USD 50 000. Consensus manipulation or governance compromise results in the full USD 250 000.

The final severity and reward amount are determined at the discretion of the Astar team by evaluating the funds at risk, possible impact, likelihood of attack, and other factors. If there are no funds at risk, the level of the bug may be downgraded or rejected.

A reward can only be provided if:

• The bug wasn't reported before.
• You do not disclose the bug to other parties or publicity until it's fixed by the Astar dev Team.
• You didn't exploit the vulnerability or allow anyone else to profit from it.
• You report a bug without any additional conditions or threats.
• The investigation was NOT conducted with Ineligible methods or Prohibited Activities, as defined in this document.
• You should reply to our additional questions regarding the reproduction of the reported bug (if they follow) within a reasonable time (up to 24h for Critical and up to 48hours for other levels of vulnerability)
• When duplicate bug reports occur, we reward only the first one if it's provided with enough information for reproduction.
• When multiple vulnerabilities are caused by one underlying issue, we will reward only the first reported.
• The vulnerability is found in the runtime pallet of Astar (no tests, or modules that aren’t in runtime, e.g. live, can be considered as vulnerability).

Astar requires KYC and an invoice to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed are Name, Address, Email. The collection of this information will be done by the Astar team. Astar may require additional KYC verification to be completed before payment can be released. Some countries are restricted when it comes to payments. This bug bounty program is only open to individuals who reside outside of the countries that are restricted by OFAC and by UNSC resolutions.

Payouts are handled by the Astar Network team directly and are denominated in USD. However, payouts are done in ASTR, SDN, USDC-ERC20, or USDT-ERC20, subjected to Astar Network discretion.
