Program Overview

Polkastarter is a protocol built for cross-chain token pools and auctions, enabling projects to raise capital in a decentralized, permissionless and interoperable environment based on Polkadot.

The platform allows cryptocurrency projects to raise funds by setting up a swap pool based on a fixed purchase rate for tokens. These so-called “Fixed Swap Pools” have many advantages for token sale investors over traditional fundraising models like ICOs, IEOs and IDOs (Initial DEX Offerings). Fixed Swap Pools will maintain the token price throughout the sale until the initial supply is bought.

With Polkastarter, decentralized projects will be able to raise and exchange capital cheap and fast. Users will be able to participate in a secure and compliant environment and to use assets that go way beyond the current ERC20 standard.

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

Any unintentional withdrawing/draining of funds from the staking contract on ETH and BSC (i.e. theft of the POLS staked)

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.

All critical bug reports must come with a PoC in order to be considered for a reward.

Critical vulnerabilities are further capped at 10% of economic damage, with the main consideration being the funds affected in addition to PR and brand considerations, at the discretion of the team. However, there is a minimum of USD 50 000 for Critical bug reports.

Payouts are handled by the Polkastarter team directly and are denominated in USD. Payouts are done in USDC or USDT, up to the discretion of the team.

Assets in Scope

All smart contracts of Polkastarter can be found at https://github.com/polkastarter. However, only those in the Assets in Scope table are considered as in-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/Blockchain

Loss of user funds staked (principal) by freezing or theft.

Web/App

Anything that can lead to loss of user funds.

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
  • 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
