DFX Finance

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.

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:

• https://github.com/dfx-finance/protocol-v3/tree/main/audits

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

Though only the proxy contracts are listed as in-scope, current implementation and any further updates to the implementation contracts are considered in scope. When reporting a bug, please make sure to select the relevant proxy smart contract as the target.

If an impact can be caused to any other asset managed by DFX 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.
