Program Overview

The Lendr Network is a borrowing protocol offering interest-free loans on Real World Asset (RWA) Stablecoins. Lendr is decentralized and governance-free.

For more information about Lendr Network, please visit https://lendr.network/

Lendr Network provides rewards in USDT (BEP20). For more details about the payment process, please view the Rewards by Threat Level section further below.

KYC Requirement

The provision of KYC is required to receive a reward for this bug bounty program where the following information will be required to be provided:

  • Government ID/Passport
  • Proof of Residency

KYC information is only required on confirmation of the validity of a bug report.

Responsible Publication

Lendr Network 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

Lendr Network adheres to the Primacy of Impact for the following severity levels:

  • Smart Contract - Critical
  • Smart Contract - High
  • Web/App - Critical
  • Web/App - High
  • Web/App - Medium

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

Lendr Network commits to providing Known Issue Assurance to bug submissions through their program. This means that Lendr Network 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

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

Rewards by Threat Level

Rewards are distributed according to the impact the vulnerability could otherwise cause based on the Impacts in Scope table further below.

Repeatable Attack Limitations

In cases of repeatable attacks for smart contract bugs, only the first attack will be counted, regardless of whether the smart contract is upgradable, pausable, or killable.

Restrictions on Security Researcher Eligibility

Security researchers who fall under any of the following are ineligible for a reward

  • OFAC residents

Previous Audits

Lendr Network has provided these completed audit review reports for reference. Any unfixed vulnerability mentioned in these reports are not eligible for a reward.

Proof of Concept (PoC) Requirements

A PoC is required for the following severity levels:

  • Smart Contract - Critical
  • Smart Contract - High
  • Smart Contract - Medium
  • Smart Contract - Low
  • Web/App - Critical
  • Web/App - High
  • Web/App - Medium
  • Web/App - Low

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.

Reward Payment Terms

Payouts are handled by the Lendr Network team directly and are denominated in USD. However, payments are done in USDT (BEP20).

Assets in scope

All code of Lendr Network can be found at https://github.com/orgs/Lendr-Network/repositories. Documentation for the assets provided in the table can be found at https://whitepaper.lendr.network/.

Unless explicitly listed, only pages of the web/app assets in addition to the direct link are considered in-scope of the bug bounty program. Other subdomains are not considered as in-scope. However, for subdomain takeovers that lead to an impact on the in-scope asset, please refer to our page about Reported Subdomain Takeovers.

Out of Scope & Rules

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 Contracts and Blockchain/DLT

  • Incorrect data supplied by third party oracles
    • Not to exclude oracle manipulation/flash loan attacks\
