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

If an impact can be caused to any other asset managed by JustLend DAO that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project. This only applies to Critical impacts.

JustLend DAO is a TRON-powered money market protocol aimed at establishing fund pools whose interest rates are determined by an algorithm based on the supply and demand of TRON assets.

JustLend DAO Smart Contracts

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.2](https://immunefi.com/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.

All Critical Smart Contract bug reports require a PoC and a suggestion for a fix to be eligible for a reward. All High and Medium Smart Contract bug reports require a suggestion for a fix to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.

Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team.

All vulnerabilities marked in the [Certik security review](https://drive.google.com/file/d/1oQxMD3DY2VHodDVQKf2047hRg9PCMkG_/view?usp=sharing) are not eligible for a reward.
