Program Overview

OpenZeppelin is the premier crypto cybersecurity technology and services company, trusted by the most used DeFi and NFT projects. Founded in 2015 with the mission to protect the open economy, OpenZeppelin provides a complete suite of security products to build, manage, and inspect all aspects of software development and operations for Ethereum projects.

OpenZeppelin safeguards tens of billions of dollars in funds for leading crypto organizations including Coinbase, Ethereum Foundation, Compound, Aave, TheGraph, and many others.

This bug bounty program is focused on their smart contracts and is focused on preventing:

  • Loss of funds by freezing or theft
  • Denial of service (smart contract is made unable to operate)
  • Access control is bypassed, including privilege escalation
  • Smart contract does not behave as intended

This is an overlay bug bounty program for OpenZeppelin’s contracts library. A vulnerability in an OpenZeppelin library would likely affect many other projects and could trigger various other bounties. This program would be potentially additive to these cases.

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.

The rewards stated here are additive to any existing bug bounty programs hosted by projects that are currently using OpenZeppelin contracts.

Critical severity bug reports must come with a PoC in order to be considered for a reward.

Payouts are handled by the OpenZeppelin team directly and are denominated in USD. However, payouts are done in ETH or USDC.

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)
  • Susceptibility to block timestamp manipulation
  • Lack of liquidity
  • Best practice critiques
  • Sybil attacks

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
