Universal Page

Universal Page’s mission is to make digital ownership more accessible and user-friendly. Everyone should be able to own their identity and digital assets on the internet. We are building the tools to make this happen.

For more information about Universal Page, please visit https://universal.page/.

Universal Page provides rewards in USDT, denominated in USD. For more details about the payment process, please view the Rewards by Threat Level section further below.

KYC Requirement

Universal Page will be requesting KYC information in order to pay for successful bug submissions. The following information will be required:

• Full name
• Date of birth
• Proof of address (either a redacted bank statement with address or a recent utility bill)
• Copy of Passport or other Government issued ID
• Eligibility Criteria

Security researchers who wish to participate must adhere to the rules of engagement set forth in this program and cannot be:

• On OFACs SDN list
• Official contributor, both past or present
• Employees and/or individuals closely associated with the project
• Security auditors that directly or indirectly participated in the audit review

Responsible Publication

Universal Page adheres to category 3 - Approval Required. This Policy determines what information researchers are allowed to make public from their submitted bug reports. For more information about the category selected, please refer to our Responsible Publication page.

Primacy of Impact vs Primacy of Rules

Universal Page adheres to the Primacy of Impact for the following impacts:

• Smart Contract - Critical
• Smart Contract - High

Primacy of Impact means that the impact is prioritized rather than a specific asset. This encourages security researchers to report on all bugs with an in-scope impact, even if the affected assets are not in scope. For more information, please see Best Practices: Primacy of Impact

When submitting a report on Immunefi’s dashboard, the security researcher should select the Primacy of Impact asset placeholder. If the team behind this project has multiple programs, those other programs are not covered under Primacy of Impact for this program. Instead, check if those other projects have a bug bounty program on Immunefi.

If the project has any testnet and/or mock files, those will not be covered under Primacy of Impact.

All other impacts are considered under the Primacy of Rules, which means that they are bound by the terms and conditions set within this program.

Proof of Concept (PoC) Requirements

A PoC, demonstrating the bug's impact, is required for this program and has to comply with the Immunefi PoC Guidelines and Rules.

Known Issue Assurance

Universal Page commits to providing Known Issue Assurance to bug submissions through their program. This means that Universal Page will either disclose known issues publicly, or at the very least, privately via a self-reported bug submission.

In a potential scenario of a mediation, this allows for a more objective and streamlined process, in order to prove that an issue is known. Otherwise, assuming the bug report is valid, it would result in the report being considered as in-scope, and due a reward.

Public Disclosure of Known Issues

Bug reports covering previously-discovered bugs (listed below) are not eligible for a reward within this program. This includes known issues that the project is aware of but has consciously decided not to “fix”, necessary code changes, or any implemented operational mitigating procedures that can lessen potential risk.

• Slither automated report
• Self Audit

Previous Audits

Universal Pages completed audit reports can be found at https://github.com/Universal-Page/contracts/blob/main/audits/2023-1-9-UniversalPage.md and https://github.com/Universal-Page/contracts/blob/main/audits/2024-2-1-UniversalPage-Vault-security-review.pdf. Any unfixed vulnerabilities mentioned in these reports are not eligible for a reward.

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.

Immunefi Standard Badge

By adhering to Immunefi’s best practice recommendations, Universal Page has satisfied the requirements for the Immunefi Standard Badge.

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.3.

Repeatable Attack Limitations

If the smart contract where the vulnerability exists can be upgraded or paused, only the initial attack will be considered for a reward. This is because the project can mitigate the risk of further exploitation by upgrading or pausing the component where the vulnerability exists. The reward amount will depend on the severity of the impact and the funds at risk.

Reward Calculation for High Level Reports

High vulnerabilities concerning theft/permanent freezing of unclaimed yield/royalties are rewarded USD 2000, capped at the maximum high reward.

In the event of temporary freezing, the reward doubles from the full frozen value for every additional 24h that the funds are temporarily frozen, up until a max cap of the high reward. This is because as the duration of the freezing lengthens, the potential for greater damage and subsequent reputational harm intensifies. Thus, by increasing the reward proportionally with the frozen duration, the project ensures stronger incentives for bug disclosure of this nature.

Reward Payment Terms

Payouts are handled by the Universal Page team directly and are denominated in USD. However, payments are done in USDT

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.

These impacts are out of scope for this bug bounty program.

All Categories:

• Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
• Impacts caused by attacks requiring access to leaked keys/credentials
• Impacts caused by attacks requiring access to privileged addresses (governance, strategist) except in such cases where the contracts are intended to have no privileged access to functions that make the attack possible
• Impacts relying on attacks involving the depegging of an external stablecoin where the attacker does not directly cause the depegging due to a bug in code
• Mentions of secrets, access tokens, API keys, private keys, etc. in Github will be considered out of scope without proof that they are in-use in production
• Best practice recommendations
• Feature requests
• Impacts on test files and configuration files unless stated otherwise in the bug bounty program

Smart Contract Specific:

• Incorrect data supplied by third party oracles
  • Not to exclude oracle manipulation/flash loan attacks
• Impacts requiring basic economic and governance attacks (e.g. 51% attack)
• Lack of liquidity impacts
• Impacts from Sybil attacks
• Impacts involving centralization risks

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
