Program Overview

Value DeFi is a complete solution on the ETH and BSC networks that aims to bring fairness, true value, and innovation to decentralized finance through a suite of high-performing products and services. They achieve this with the following products:

vSwap - highly-competitive automated market-maker and decentralized exchange that allows anyone to create custom liquidity pools with flexible ratio pairs and swap fees.

vPegSwap - Solidity implementation of Curve’s StableSwap that is considered a fully automated market maker for tightly pegged assets or stablecoins.

vFarm - a pool that distributes predefined token(s) to its farmers at every block. There are two types of vFarms, those that were created by Value DeFi and those that were created by other projects using our Farms-as-a-Service (FaaS) technology. Farms-as-a-Service (FaaS) is a free decentralized self-serving platform that any project can use to create and customize time-saving and low-fee liquidity mining solutions.

vSafe - yield aggregators that use multiple strategies to maximize interest rate returns on users' assets.

vTokens - newly developed synthetic cross-chain algorithmic tokens. vTokens can be developed on Ethereum, Binance and Polkadot while being pegged to any other tokens using Chainlink’s services.

vGovernance - where people who stake $VALUE make major decisions regarding Value DeFi and earn a portion of the profits made by products of the platform

The bug bounty program covers its smart contracts and app and is focused around the prevention of loss of user funds and the leak of critical data.

Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

Critical payouts have a maximum total payout of 10% of the funds that are directly affected with a payout floor of USD 50 000.

Payouts are handled by the Value DeFi team directly and are denominated in USD. Payouts are done in BUSD, USDT, USDC, DAI, vBSWAP (Binance Smart Chain), or VALUE (Ethereum).

Assets in Scope

Web and App bug reports are accepted within the scope of this bug bounty program, but have no payout.

Prioritized Vulnerabilities

We are especially interested in receiving and rewarding vulnerabilities of the following types:

Smart Contracts/Blockchain:

  • Re-entrancy
  • Logic errors
    • including user authentication errors
  • Solidity/EVM details not considered
    • including integer over-/under-flow
    • including unhandled exceptions
  • Trusting trust/dependency vulnerabilities
    • including composability vulnerabilities
  • Oracle failure/manipulation
  • Novel governance attacks
  • Economic/financial attacks
    • including flash loan attacks
  • Congestion and scalability
    • including running out of gas
    • including block stuffing
    • including susceptibility to frontrunning
  • Consensus failures
  • Cryptography problems
    • Signature malleability
    • Susceptibility to replay attacks
    • Weak randomness
    • Weak encryption
  • Susceptibility to block timestamp manipulation
  • Missing access controls / unprotected internal or debugging interfaces

Accepted Web/App Vulnerabilities

We accept the following website/app vulnerabilities, though there is no reward for them:

  • Remote Code Execution
  • Trusting trust/dependency vulnerabilities
  • Vertical Privilege Escalation
  • XML External Entities Injection
  • SQL Injection
  • Horizontal Privilege Escalation
  • Stored XSS
  • Reflective XSS with impact
  • CSRF with impact
  • Direct object reference
  • Internal SSRF
  • Session fixation
  • Insecure Deserialization
  • SSL misconfigurations
  • SSL/TLS issues (weak crypto, improper setup)
  • URL redirect
  • Clickjacking (must be accompanied with PoC)
  • Misleading Unicode text (e.g. using right to left override characters)

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)
  • 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

The following vulnerabilities are not sought after for website bug reports:

  • Theoretical vulnerabilities without any proof or demonstration
  • Content spoofing / Text injection issues
  • Self-XSS
  • Captcha bypass using OCR
  • CSRF with no security impact (logout CSRF, change language, etc.)
  • Missing HTTP Security Headers (such as X-FRAME-OPTIONS) or cookie security flags (such as “httponly”)
  • Server-side information disclosure such as IPs, server names, and most stack traces
  • Vulnerabilities used to enumerate or confirm the existence of users or tenants
  • Vulnerabilities requiring unlikely user actions
  • URL Redirects (unless combined with another vulnerability to produce a more severe vulnerability)
  • Lack of SSL/TLS best practices
  • DDoS vulnerabilities
  • Attacks requiring privileged access from within the organization

The following activities are prohibited by 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
