Themis Protocol

Themis is a decentralized borrowing & lending protocol built on Ethereum. It is compatible with ERC-721/ERC-1155 assets and enables users to create anonymous lending between stablecoins and bluechip assets. Starting with Uniswap-V3 LP positions.

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

• Loss of user funds staked (principal) by freezing or theft
• Theft of unclaimed yield
• Smart contract gas drainage
• Smart contract fails to deliver promised returns, but doesn’t lose value
• Taking Down the application/website
• Signing transactions for other users
• Redirection of user deposits and withdrawals

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2. 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 bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required. In addition, all bug reports must also come with a suggestion for a fix in order to be considered for a reward.

All issues previously highlighted in the following audit report are considered out of scope:

• https://github.com/peckshield/publications/blob/master/audit_reports/PeckShield-Audit-Report-ThemisV3-v1.0.pdf

Payouts are handled by the Themis Protocol team directly and are denominated in USD. However, payouts are done in USDC or USDT, at the discretion of the team.

Smart Contract

Websites and Applications

All smart contracts of Themis Protocol can be found at https://github.com/Themis-protocol/Solidity-Open-Source. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

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
• 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
• Feature requests
• Best practices
• Vulnerabilities primarily caused by browser/plugin defects
• Any vulnerability exploit requiring CSP bypass resulting from a browser bug

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
