Only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

Though only the proxy contracts are listed as in-scope, current implementation and any further updates to the implementation contracts are considered in scope. When reporting a bug, please make sure to select the relevant proxy smart contract as the target. 

If an impact can be caused to any other asset managed by Ankr that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project. This only applies to Critical impacts.

Ankr is a decentralized blockchain infrastructure provider that operates an array of nodes globally distributed across over 50 Proof-of-Stake networks.

Rewards are distributed according to the impact of the vulnerability based on the  [Immunefi Vulnerability Severity Classification System V2.2](https://immunefi.com/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. Explanations and statements are not accepted as PoC and code is required.

Critical smart contract vulnerabilities are capped at 5% of economic damage, primarily taking into consideration funds at risk. However, there is a minimum reward of __USD 10 000__. 

All other rewards for the Ankr bug bounty program are scaled based on an internally established team criteria, taking into account the exploitability of the bug, the impact it causes, and the likelihood of the vulnerability presenting itself, which is especially factored in with bug reports requiring multiple conditions to be met that are currently not in-place. However, there is a minimum reward of __USD 1 000__ for each severity level, rewards will be provided at the determined fair value by the team depending on these conditions, assuming that the bug report is in-scope of the bug bounty program.

The following vulnerabilities marked in [https://www.ankr.com/docs/staking/extra/audit-reports/](https://www.ankr.com/docs/staking/extra/audit-reports/) are not eligible for a reward.

Payouts are handled by the Ankr team directly and are denominated in USD. However, payouts are done in __ANKR, USDT and USDC__, with the choice of the ratio at the discretion of the team.
