Critical Reward Calculation

Mainnet assets:

Reward amount is 15% of the funds directly affected up to a maximum of:

$50,000

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. 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.

Reward Calculation for Critical Level Reports

For critical smart contract bugs, the reward amount is 15% of the extractable value up to a maximum of USD 50 000. The calculation of the amount of extractable value is based on the time and date the bug report is submitted. However, a minimum reward of USD 10 000 is to be rewarded in order to incentivize security researchers against withholding a bug report.

Reward Calculation for High Level Report

For high severity smart contract bugs, the reward amount is 15% of the extractable value up to a maximum of USD 10 000. The calculation of the amount of extractable value is based on the time and date the bug report is submitted. However, a minimum reward of USD 2 000 is to be rewarded in order to incentivize security researchers against withholding a bug report.

All Critical and High Smart Contract 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.

Known issues highlighted in the following audit reports are considered out of scope:

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

Program Overview

DFX Finance is a decentralized foreign exchange (FX) protocol optimized for trading fiat-backed foreign stablecoins, (CADC, EUROC, XSGD, etc.). You can safely earn yield or use the DFX platform and its contracts to provide true financial localization for the customers of your global business. The next generation of global finance cannot rely solely on USD-pegged stablecoins. A decentralized protocol where users can swap non-USD stablecoins pegged to various foreign currencies is not only important, but necessary.

KYC not required

No KYC information is required for payout processing.

Proof of Concept

Proof of concept is always required for all severities.

Prohibited Activities

Default prohibited activities
  • Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
  • 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 that are executed against project assets
  • Automated testing of services that generates significant amounts of traffic
  • Public disclosure of an unpatched vulnerability in an embargoed bounty
  • Any other actions prohibited by the Immunefi Rules

Feasibility Limitations

The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.

Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.
