Program Overview

Shadow Farm are strategies that allow users to earn boosted yields on dexes.

Shadow farms allow our users to stake their SpiritSwap, SpookySwap, and Beethoven-x LPs and earn their respective governance token. The strategies will harvest the rewards multiple times a day, and swap them for their respective yield-bearing version (xBOO, fBEETS, linSPIRIT) and stake them. A performance fee will be applied only on the compounded rewards. In some cases, like SpiritSwap, we hold their locked version (eg.: inSpirit) earning a boost yield on their farms.

For more information about Shadow Farm, please visit the document page or Liquid Driver website.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.1. 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 High and Critical Smart Contract bug reports require a PoC and a suggestion for a fix to be eligible for a reward. Explanations and statements are not accepted as PoC and code is required.

Payouts are handled by the Shadow Farm team directly and are denominated in USD. However, payouts are done in LQDR or USDC.

Assets in scope

All smart contracts of Shadow Farm can be found at LiquidDriver-finance · GitHub. 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 Shadow Farm 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.

Out of Scope & Rules

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
  • Centralization risks

Websites and Apps

  • Theoretical vulnerabilities without any proof or demonstration
  • Attacks requiring physical access to the victim device
  • Attacks requiring access to the local network of the victim
  • Reflected plain text injection ex: url parameters, path, etc.
    • This does not exclude reflected HTML injection with or without javascript
    • This does not exclude persistent plain text injection
  • Self-XSS
  • Captcha bypass using OCR without impact demonstration
  • CSRF with no state modifying security impact (ex: logout CSRF)
  • Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”) without demonstration of impact
  • Server-side non-confidential information disclosure such as IPs, server names, and most stack traces
  • Vulnerabilities used only to enumerate or confirm the existence of users or tenants
  • Vulnerabilities requiring un-prompted, in-app user actions that are not part of the normal app workflows
  • Lack of SSL/TLS best practices
  • DDoS vulnerabilities
  • Feature requests
  • Issues related to the frontend without concrete impact and PoC
  • Best practices issues without concrete impact and PoC
  • Vulnerabilities primarily caused by browser/plugin defects
  • Leakage of non sensitive api keys ex: etherscan, Infura, Alchemy, etc.
  • Any vulnerability exploit requiring browser bugs for exploitation. ex: CSP bypass

The following activities are prohibited by this 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
