Instadapp

The Instadapp platform is a full feature platform for both users and developers to leverage the full potential of DeFi. The Instadapp protocol ('DSL') acts as the middleware that aggregates multiple DeFi protocols into one upgradable smart contract layer. This structure allows Instadapp to access the full potential of Decentralized Finance.

The main functionalities of the DSL are account extensions and upgradability. The unique upgradability means that the upcoming and new extensions will be upgraded, maintained and managed by INST governance. The DSL also includes a new operability layer that acts as a ‘Account Extension.’ These extensions allow the user to access new and unique functionality for their DSL account. These extensions and the evolution of the platform form a DeFi hub through which new use cases and extensions can be created, some examples of possible use cases include: Flash Loan Module, Authority extension, L2 extension, etc.

This bug bounty program is focused on their smart contracts and dapp and is focused on preventing the following impacts:

• Deletion of user data
• Theft of governance funds
• Thefts and freezing of principal of any amount
• Thefts and freezing of unclaimed yield of any amount

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.

A PoC and a suggestion for a fix is required for Critical and High vulnerabilities. Medium level bug reports must come with a suggestion for a fix.

Bugs resulting in temporary freezing of funds are not eligible for a reward.

Payouts are handled by the Instadapp team directly and are denominated in USD. However, payouts are done in ETH or INST, at the discretion of the team.

All code of Instadapp can be found at https://github.com/Instadapp. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

All folders and files labeled with the words “test”, “mock/mocks”, or “dummy” are out-of-scope of the bug bounty program.

Impacts in Scope

Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.

Smart Contracts

• Any kind where the user's funds are lost

Web/App

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
• Feature requests
• Best practices

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
