Rewards
Rewards by Threat Level
Mainnet assets:
Reward amount is 10% of the funds directly affected up to a maximum of:
$500,000Rewards 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. 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/ 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.
Program Overview
Ankr is a decentralized blockchain infrastructure provider that operates an array of nodes globally distributed across over 50 Proof-of-Stake networks.
Ankr Staking makes cross-chain staking, liquid staking, and other yield-earning opportunities simple and accessible to all crypto investors. Ankr has created a scalable, flexible and decentralized staking mechanism that resolves the capital inefficiency of Proof-of-Stake networks and similar blockchain consensus mechanisms. Stake your crypto and get liquid staking tokens or use liquid staking to boost your yield.

KYC not required
No KYC information is required for payout processing.
Proof of Concept
Proof of concept is always required for all severities.
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.
