Blockchain/DLT - Teleporter: Excluding everything under https://github.com/ava-labs/teleporter/tree/main/contracts/src/CrossChainApplications/examples

Ava Labs makes it simple to deploy high-performance solutions for Web3, led by innovations on Avalanche. The company was founded by Cornell computer scientists, who partnered with Wall Street veterans and early Web3 leaders to execute a promising vision for redefining the way people build and use open, permissionless networks.

Shutdown of greater than 10% or equal to but less than 30% of network processing nodes without brute force actions, but does not shut down the network

Modification of transaction fees outside of design parameters

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 Blockchain/DLT bugs, the reward amount is 10% of the funds directly affected, capped at the maximum critical reward USD $100,000.
For critical Blockchain/DLT bugs with a non-funds-at risk impact, the reward will be paid out as follows: 

  - Network not being able to confirm new transactions (total network shutdown)
USD $100,000
  - Unintended permanent chain split requiring hard fork (network partition requiring hard fork)
USD $100,000
  - Permanent freezing of funds (fix requires hardfork)
USD $100,000

For high Blockchain/DLT non-funds-at risk impacts, the reward will be paid out as follows: 

  - Causing network processing nodes to process transactions from the mempool beyond set parameters
USD $5,000

For critical smart contract bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD 100 000. 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 10 000 is to be rewarded in order to incentivize security researchers against withholding a critical bug report.

NOTE: Smart contracts deployed by third-parties on Avalanche are EXPLICITLY OUT OF SCOPE. This bug bounty ONLY includes the smart contracts listed as in scope below.

__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.    

__Reward Payment Terms__

Payouts are handled by the __Ava Labs__ team directly and are denominated in __USD__.

Please note: In cases where the size of the reward exceeds an equivalent of 10 000 USD, Ava Labs is entitled to make the payment in one-year locked AVAX at the rate calculated based on the VWAP of AVAX during 90 calendar days preceding the date of the respective validated report.
