Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.1. 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.

The bug must directly affect the protocol's deployed bondfactory and bonds created by that factory's createBond to be considered in scope of the program.

  • The following issues are considered as out of scope of this program:
  • Any issues related to malicious or exploitable tokens being added to the allow-list. It is assumed that all tokens will strictly adhere to the openzeppelin erc20 implementation
  • Intended protocol behavior (borrowers have the ability to default)
  • Best practice critiques
  • Using flash loan to pay and retrieve collateral
  • Different payment/collateral amounts given past maturity
  • Rounding errors with unrealistic ratios
  • Dust leftover in contracts
  • Vulnerabilities requiring compromised owner's wallet

In addition, issues previously highlighted in the following audit reports are considered out of scope:

Payouts are handled by the Porter Finance team directly and are denominated in USD. However, payouts are done in USDC.

Assets in scope

All smart contracts of Porter Finance can be found at https://github.com/porter-finance/v1-core. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

If an impact can be caused to any other asset managed by Porter Finance that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project.

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 Contract

  • Thefts and permanent freezing of any collateral
  • Thefts and permanent freezing of payment tokens
  • Thefts and permanent freezing of bond tokens
  • Temporarily preventing bond tokens from being converted for at least 24 hours

  • Centralization risks

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
