The bug bounty program covers its smart contracts and staking page and is focused on the prevention of loss of user funds.

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

All web and app bugs must come with a PoC in order to be accepted. All web and app bug reports without a PoC will be rejected with a request for a PoC.

The final decision of the reward, which is affected by the exploitability of the bug report, is done by the PERI Finance team.

Payouts are handled by the PERI Finance team directly and are denominated in USD. Payouts are done in USDT.

Smart Contract

Websites and Applications

Only web/app vulnerabilities that directly affect the web/app assets listed in this table are accepted within the bug bounty program. All others are out-of-scope.

Under the GitHub link, only the smart contract vulnerabilities that affect the following processes are accepted and are eligible for a reward.

• Staking PERI/USDC(Issue pUSD)
• Unstaking PERI/USDC(burn Pynths)
• Claiming(Inflationary Reward)

All testnet and mock smart contracts, even those that are around Staking, Unstaking, and Claiming, are considered as out-of-scope for this bug bounty program.

The following vulnerabilities are excluded from the rewards for this bug bounty program:

• Attacks that the reporter has already exploited themselves, leading to damage
• Attacks requiring access to leaked keys/credentials
• Attacks requiring access to privileged addresses (governance, strategist)

Smart Contracts and Blockchain

• Incorrect data supplied by third party oracles
  • Not to exclude oracle manipulation/flash loan attacks
• Basic economic governance attacks (e.g. 51% attack)
• Lack of liquidity
• Best practice critiques
• Sybil attacks

Websites and Apps

• Theoretical vulnerabilities without any proof or demonstration
• Content spoofing / Text injection issues
• Self-XSS
• Captcha bypass using OCR
• CSRF with no security impact (logout CSRF, change language, etc.)
• Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”)
• Server-side information disclosure such as IPs, server names, and most stack traces
• Vulnerabilities used to enumerate or confirm the existence of users or tenants
• Vulnerabilities requiring unlikely user actions
• URL Redirects (unless combined with another vulnerability to produce a more severe vulnerability)
• Lack of SSL/TLS best practices
• DDoS vulnerabilities
• Attacks requiring privileged access from within the organization
• Feature requests
• Best practices

The following activities are prohibited by bug bounty program:

• Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
• 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
• Automated testing of services that generates significant amounts of traffic
• Public disclosure of an unpatched vulnerability in an embargoed bounty
