All smart contracts of pStake can be found at [https://github.com/persistenceOne/stkBNB-contracts/tree/main/contracts](https://github.com/persistenceOne/stkBNB-contracts/tree/main/contracts). However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

pSTAKE is a liquid staking protocol that unlocks liquidity for your staked assets. With pSTAKE, users can securely stake their Proof-of-Stake (PoS) assets, participate in protocol improvements and security to earn staking rewards, and receive staked underlying representative tokens (stkASSETs) which can be used to explore additional yield opportunities across DeFi.


**Note**: This product is in its deprecation phase and will be sunsetted by the end of 2024. As a result, bounty amounts have been adjusted accordingly and are lower than usual.

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

Changing details of other users (including modifying browser local storage) without already-connected wallet interaction and with significant user interaction such as iframing leading to modifying the backend/browser state (demonstrate impact with PoC)

Any impact involving a publicly released CVE without a working PoC

Taking over broken or expired outgoing links such as social media handles, etc.

Temporarily disabling user to access target site, such as locking up the victim from login, cookie bombing, etc.

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.3](https://immunefi.com/immunefi-vulnerability-severity-classification-system-v2-3/). 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 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.

__Smart Contracts Rewards Breakdowns__

Smart Contracts (Critical):
  - Loss of user funds:
    - 10% of assets at risk, minimum __USD 50 000__, maximum __USD 300 000__
  - Loss of non-user funds (e.g. treasury):
    - 10% of assets at risk, minimum __USD 25 000__, maximum __USD 200 000__

Smart Contracts (High):
  - 10% of assets at risk
  - Minimum __USD 20 000__, maximum of __USD 100 000__

Previous issues highlighted in the following audit reports are considered out of scope: 
  - [PeckShield Audit Report](https://github.com/persistenceOne/pStake-auditReports/blob/main/stkBNB/pStake_stkBNB_Smart_Contract_Audit_Peckshield%20%5B04.07.2022%5D.pdf)
  - [Halborn Audit Report](https://github.com/persistenceOne/pStake-auditReports/blob/main/stkBNB/pSTAKE_stkBNB_Smart_Contract_Audit_Halborn%20%5B05.08.2022%5D.pdf)

In addition, the following issue are known and considered out of scope of the program: 

The gas consumed by claim __All()__ depends on the number of unstake requests made by the user calling the __claimAll()__ function. The higher the number of unstake requests made by the user, the higher the gas usage of the __claimAll()__ function will be. The more unstake requests they create, the more gas they will have to pay for __claimAll()__.

Payouts are handled by the __pStake__ team directly and are denominated in USD. However, payouts are done in __PSTAKE__, __BUSD__ or __USDC__, at the discretion of the team.
