This bug bounty program is focused on their smart contract and is focused on preventing:

• Thefts and freezing of principal of any amount
• Thefts and freezing of unclaimed yield of any amount
• Theft of governance funds

Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System. This is a simplified 5-level scale, with separate scales for websites/apps and smart contracts/blockchains, encompassing everything from consequence of exploitation to privilege required to likelihood of a successful exploit.

All High and Critical Smart Contract bug reports require a suggestion for a fix to be eligible for a reward.

Critical smart contract vulnerabilities are capped at 10% of economic damage, primarily taking into consideration funds at risk, but also PR and branding aspects, at the discretion of the team. However, there is a minimum reward of USD 50 000.

The following vulnerabilities are not eligible for a reward:

• Attacks requiring access to leaked keys/credentials
• Attacks requiring access to privileged addresses (governance, strategist)
• All the issues that are listed here, inclusive of marked as “Confirmed” or “Fixed” in the Audit Reports

Payouts are handled by the HurrianceSwap team directly and are denominated in USD. However, payouts are done in HCT, USDT or USDC.

All smart contracts of HurricaneSwap can be found at https://github.com/HurricaneSwap/v2-contract/tree/main/avax. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.

Impacts in Scope

Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.

Smart Contracts/Blockchain

• Loss of user funds staked (principal) by freezing or theft
• Theft of unclaimed yield
• Freezing of unclaimed yield
• Temporary freezing of funds for at least 48 hours
• Unable to call smart contract
• Smart contract fails to deliver promised returns

We are especially interested in receiving and rewarding vulnerabilities of the following types:

Smart Contracts and Blockchain

• Re-entrancy
• Logic errors
  • including user authentication errors
• Solidity/EVM details not considered
  • including integer over-/under-flow
  • including rounding errors
  • including unhandled exceptions
• Trusting trust/dependency vulnerabilities
  • including composability vulnerabilities
• Oracle failure/manipulation
• Novel governance attacks
• Economic/financial attacks
  • including flash loan attacks
• Congestion and scalability
  • including running out of gas
  • including block stuffing

The following vulnerabilities are excluded from the rewards for this bug bounty program:

• Attacks that the reporter has already exploited themselves, leading to damage
• Attacks requiring access to leaked keys/credentials
• Attacks requiring access to privileged addresses (governance, strategist)

Smart Contracts and Blockchain

• Incorrect data supplied by third party oracles
  • Not to exclude oracle manipulation/flash loan attacks
• Basic economic governance attacks (e.g. 51% attack)
• Lack of liquidity
• Best practice critiques
• Sybil attacks

The following activities are prohibited by this bug bounty program:

• Any testing with mainnet or public testnet contracts; all testing should be done on private testnets
• Any testing with pricing oracles or third party smart contracts
• Attempting phishing or other social engineering attacks against our employees and/or customers
• Any testing with third party systems and applications (e.g. browser extensions) as well as websites (e.g. SSO providers, advertising networks)
• Any denial of service attacks
• Automated testing of services that generates significant amounts of traffic
• Public disclosure of an unpatched vulnerability in an embargoed bounty
