Mercurial Finance

Mercurial is building new liquidity systems to maximise the utility and yield of stable assets on Solana. As the DeFi ecosystem on Solana grows, there will be many different variants of collateralized, wrapped, and synthetic assets in the space. Their most immediate objective is to provide the best liquidity for all the major stable and pegged assets on Solana, which they started with their Mainnet beta.

Mercurial Finance’s focus will be on stable coins because they represent a major part of the DeFi demand across synthetic assets creation, swapping, and lending. Robust availability of stablecoin liquidity is crucial to any DeFi ecosystem.

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

• Direct theft of user funds
• Ability to execute system commands
• Extract Sensitive data/files from the server such as /etc/passwd
• Stealing User Cookies
• Taking Down the application/website

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2. 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 web/app 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. In addition, all bug reports must also come with a suggestion for a fix to be considered for a reward.

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