Program Overview

The 1inch Network unites decentralized protocols whose synergy enables the most lucrative, fastest and protected operations in DeFi. The initial protocol of the 1inch Network is a DEX aggregator solution that searches deals across multiple liquidity sources, offering users better rates than any individual exchange.

The bug bounty program is focused around its smart contracts and website, and is mostly aimed at addressing serious security issues directly affecting fund safety and wrong price estimations. The program is further covered by the Armor Alliance Bug Bounty Challenge.

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 listed rewards represent the maximum that will be paid out for a security bug reporting.

All web and app bugs are required to have a proof of concept (PoC) in order to be considered for a reward.

The maximum payout for a “Critical” bounty for both smart contract and web and app bugs is 10% of the potential economic damage, or USD 200 000 for smart contract bugs and USD 100 000 for web/app bugs, whichever is lower.

Payouts are handled by 1inch directly and are denominated in USD. Payouts up to USD 100 000 are made in 1INCH. For payments above USD 100 000, the remainder is paid in $ARMOR by the ArmorFi team under the Armor Alliance Bug Bounty Challenge with a vesting period of up to 24 months.

Assets in Scope

Web/App vulnerabilities that don’t directly affect the assets in scope are not accepted within this bug bounty program.

Prioritized Vulnerabilities

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

Smart Contracts and Blockchain

  • Re-entrancy
  • Logic errors
    • including user authentication errors
  • Solidity/EVM details not considered
    • including integer over-/under-flow

    • 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

Websites and Apps

  • Remote Code Execution
  • Trusting trust/dependency vulnerabilities
  • Vertical Privilege Escalation
  • XML External Entities Injection
  • SQL Injection
  • LFI/RFI
  • Horizontal Privilege Escalation
  • Stored XSS
  • Reflective XSS with impact
  • CSRF
  • CSRF with impact
  • Direct object reference
  • Internal SSRF
  • Session fixation
  • Insecure Deserialization
  • Path Traversal
  • DOM XSS
  • SSL misconfigurations
  • SSL/TLS issues (weak crypto, improper setup)
  • URL redirect
  • Clickjacking
  • Misleading Unicode text (e.g. using right to left override characters)
  • Coercing the application to display/return specific text to other users

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

Websites and Apps

  • 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
