This bug bounty program focuses on the Kinesis Bridge, a cross-chain bridge that leverages the Hyperlane protocol. The program primarily covers the bridge's smart contract implementation, cross-chain messaging and validation system, and verification mechanisms for secure asset transfers and bridging operations between supported networks. 

Block stuffing

Temporary freezing of funds

Theft of unclaimed yield

Smart contract unable to operate due to lack of token funds

Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol)

Theft of gas

Unbounded gas consumption

Contract fails to deliver promised returns, but doesn't lose value

Network not being able to confirm new transactions (total network shutdown)

Temporary freezing of NFTs

Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yield

Permanent freezing of unclaimed royalties

Unintended permanent chain split requiring hard fork (network partition requiring hard fork)

Permanent freezing of funds (fix requires hardfork)

Kinesis Bridge Codebase

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.3. 
Reward Calculation for Critical Level Reports

For critical smart contract bugs, the reward amount is 10% of the funds directly affected up to a maximum of USD $50,000. 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 $25,000 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 attack 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 rewarded within a range of $10,000 to $25,000 depending on the funds at risk, capped at the maximum high reward.  

In the event of temporary freezing, the reward doubles 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 lengthens, 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__

Kadena will be issuing the payment of the bounties on behalf of the Ideasoft team, who owns and operates the Kinesis bridge

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.

Kadena provides rewards in either the native tokens known as “Kadena” and that carry the trading symbol KDA (“KDA”), USDC, USDT or a combination thereof, as determined by Kadena in its discretion, for valid, approved and accepted Bug Reports for various projects within the Kadena public blockchain ecosystem (the “Ecosystem”). Payment of any Research Fee will be made, and any KDA, USDC or USDT delivered, within thirty (30) days of Kadena’s approval or acceptance of a Bug Report to a wallet that supports KDA, USDC or USDT and which corresponds to the public key that such Security Researcher provides to Kadena in writing. If the payment of an applicable Research Fee is satisfied in whole or in part by delivery of KDA, the USD equivalency of each KDA so delivered shall be equal to the closing price of KDA (denominated in KDA and as reported by CoinMarketCap) on the date on which the Security Researcher submits a Bug Report which is ultimately approved or accepted by Kadena. Each Security Researcher bears all market risk related to the volatility of KDA between the date of the Kadena’s receipt of such Security Researcher’s Bug Report and the actual date of delivery of KDA.  For more details about the payment process, please view the Rewards by Threat Level section further below.
