The Elixir network is a new primitive, purpose-built to power the next generation of institutional liquidity. Elixir powers deUSD – a fully collateralized, yield-bearing synthetic dollar. 

Elixir is the most widely adopted network by RWAs: bringing funds from BlackRock, Hamilton Lane, and others to DeFi for the first time through deUSD. The Elixir network is secured by 10,000+ global validators.

Through Elixir's natively integrating with funds, deUSD serves as the primary rails for RWA assets to natively enter the crypto economy. Used exclusively by Securitize and others, deUSD is the default currency enabling holders to use DeFi without changing their original asset exposure. 

Hamilton Lane and other leading institutions have directly allocated to deUSD within their RWAs, integrating the Elixir network for instant onchain liquidity for their funds.

Elixir Protocol Documentation

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.3. ](https://immunefi.com/immunefi-vulnerability-severity-classification-system-v2-3/)

For critical smart contract bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD $250,000. The calculation of the amount of funds at risk is based on the time and date the bug report is submitted. However, a minimum reward of USD $75,000 is to be rewarded in order to incentivize security researchers against withholding a critical bug report.

__Repeatable Attack Limitations__

- If the smart contract where the vulnerability exists can be upgraded or paused, only the initial attacks within the first hour will be considered for a reward. This is because the project can mitigate the risk of further exploitation by upgrading or pausing the component where the vulnerability exists. The reward amount will depend on the severity of the impact and the funds at risk. 
- For critical repeatable attacks on smart contracts that cannot be upgraded or paused, the project will consider the cumulative impact of the repeatable attacks for a reward. This is because the project cannot prevent the attacker from repeatedly exploiting the vulnerability until all funds are drained and/or other irreversible damage is done. Therefore, this warrants a reward equivalent to 10% of funds at risk, capped at the maximum critical reward. 

__Reward Calculation for High Level Reports__

- High vulnerabilities concerning theft/permanent freezing of unclaimed yield/royalties are considered at the full amount of funds at risk, capped at the maximum high reward. This is to incentivize security researchers to uncover and responsibly disclose vulnerabilities that may have not have significant monetary value today, but could still be damaging to the project if it goes unaddressed.   
- In the event of temporary freezing, the reward increases at a multiplier of two from the full frozen value for every additional 24h that the funds are temporarily frozen, up until a max cap of the high reward. This is because as the duration of the freezing lenghents, the potential for greater damage and subsequent reputational harm intensifies. Thus, by increasing the reward proportionally with the frozen duration, the project ensures stronger incentives for bug disclosure of this nature.    

For critical web/apps bug reports will be rewarded with $50,000, only if the impact leads to:
- A loss of funds involving an attack that does not require any user action
- Unauthorized minting of tokens on-chain
- Private key or private key generation leakage leading to unauthorized access to user funds 

All other impacts that would be classified as Critical would be rewarded a flat amount of $10,000. The rest of the severity levels are paid out according to the Impact in Scope table.  

__Reward Payment Terms__

Payouts are handled by the Elixir Protocol team directly and are denominated in USD. However, payments are done in $USDC.

The calculation of the net amount rewarded is based on the average price between CoinMarketCap.com and CoinGecko.com at the time the bug report was submitted. No adjustments are made based on liquidity availability.
