Responsible Publication

Lybra Finance adheres to category 3. This Policy determines what information whitehats 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

Lybra Finance adheres to the Primacy of Impact for the following impacts:

• Smart Contract, Critical
• Smart Contract, High
• Smart Contract, Medium
• Smart Contract, Low

If a category’s severity level is covered within the Primacy of Impact, it means that even if the impacted asset is not in-scope but is owned by the project, then it would be considered as in-scope of the bug bounty program as long as it involves an impact under that respective severity level. When submitting a report, just select the Primacy of Impact asset placeholder. If the team behind this project has multiple projects, those other projects are not covered under the Primacy of Impact of this program. Instead, check if those other projects have a bug bounty program on Immunefi.

Testnet and mock files are not covered under the Primacy of Impact.

All other severity levels not listed here are considered under the Primacy of Rules, which means that they are bound by the terms of the bug bounty program.

Known Issue Assurance

Lybra Finance commits to providing Known Issue Assurance to bug submissions through their program. This means that Lybra Finance will either disclose known issues publicly or at the very least privately via a self-reported bug submission in order to allow for a more objective and streamlined mediation process to prove that an issue is known. Otherwise, assuming the bug report itself is valid, it would result in the bug report being considered in-scope and due 100% of the reward with respect to the bug bounty program terms.

Immunefi Standard Badge

Lybra Finance has satisfied the requirements for the Immunefi Standard Badge, which is given to projects that adhere to our best practices.

Rewards 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.

For the purposes of determining report validity, this is a Primacy of Impact program. Learn more about report validity best practices here: Best Practice - Primacy of Impact vs Primacy of Rules.

All smart contract 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. To determine the final reward amount, the likelihood to have a meaningful impact on availability, integrity, and/or loss of funds is considered. The final decision on the payout amount will be determined by the Lybra Finance team at its discretion.

Known issues highlighted in the following audit reports are considered out of scope:

Proof of Concept (PoC) Requirements

A PoC is required for the following severity levels:

• Smart Contract Critical severity impacts
• Smart Contract High severity impacts
• Smart Contract Medium severity impacts
• Smart Contract Low severity impacts
• Smart Contract Informational severity impacts

All PoCs submitted must comply with the Immunefi-wide PoC Guidelines and Rules. Bug report submissions without a PoC when a PoC is required will not be provided with a reward.
