Push Protocol is the communication protocol of web3. Push enables cross-chain notifications (on chain / off chain), messaging, video for dapps, wallets, and services tied to wallet addresses in an open, gasless, and platform-agnostic fashion. The open communication layer allows any crypto wallet / frontend to tap into the network and get the communication across.

Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield

Permanent freezing of funds

Drain of Funds from contract

Loss of funds due to bridging of tokens

Theft of unclaimed yield

Permanent freezing of unclaimed yield

Temporary freezing of funds

User/Stakers being able to harvest more tokens than they should be able to.

User/Stakers being able to harvest without staking for at least 1 complete epoch.

Smart contract unable to operate due to lack of token funds

Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol)

Unbounded gas consumption

Unfair reward distribution between users with equal staking details like token weight, stake duration etc.

Contract fails to deliver promised returns, but doesn't lose value

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 100,000. 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 80,000 is to be rewarded in order to incentivize security researchers against withholding a bug report. 

For High Smart Contract bugs, the reward amount is 100% of the funds directly affected up to a maximum of USD 50,000. 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.   

__Restrictions on Security Researcher Eligibility__

Security researchers who fall under any of the following are ineligible for a reward
- Any country or government or international authority, including the US Department of the Treasury’s Office of Foreign Assets Control (OFAC), the US Department of State, the United Nations Security Council, the European Union, Her Majesty's Treasury, the Hong Kong Monetary Authority or the Monetary Authority of Singapore.

__Previous Audits__

Push Protocol has provided these completed audit review reports for reference. Any unfixed vulnerability mentioned in these reports are not eligible for a reward.
- [Push Protocol V1 Audit Report](https://github.com/ChainSafe/audits/blob/main/EPNS/epns-protocol-10-2021.pdf)
- [Push Protocol V1.5 Audit Report](https://github.com/ChainSafe/audits/blob/main/EPNS/epns-protocol-11-2022.pdf)
- [Push Protocol V2 Audit Report](https://github.com/ChainSafe/audits/blob/main/EPNS/epns-protocol-05-2023.pdf)

__Proof of Concept (PoC) Requirements__

A PoC is required for the following severity levels:

- Smart Contract, Critical Severity Level
- Smart Contract, High Severity Level
- Smart Contract, Medium Severity Level
- Smart Contract, Low Severity Level

All PoCs submitted must comply with the Immunefi-wide [PoC Guidelines and Rules](https://immunefisupport.zendesk.com/hc/en-us/articles/9946217628561-Proof-of-Concept-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 Push Protocol team directly and are denominated in USD. However, payments are done in PUSH.

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.
