Strike Finance

Strike is an autonomous and decentralized money market that enables variable based rates for supplying digital asset collaterals to the protocol and from borrowing digital assets from the protocol with over-collateralized assets.

The tokenization of digital assets onto the Strike protocol will unlock liquidity from that asset without having to liquidate and/or sell that asset in the market. Money Markets allow users to tap into a peer-to-peer marketplace where all interactions are validated against open-source smart contracts running on the immutable Ethereum blockchain.

The entire Strike protocol is operated by its community with no centralized control or team tokens exercising power over the protocol’s governance. Strike is designed to protect the equilibrium between borrowers and suppliers by allowing liquidators to handle bad vaults and collecting a premium for stabilizing the protocol. Strike users are in control by interacting with the STRK utility token to govern and operate the platform with consensus.

Responsible Publication

Strike Finance adheres to category 3 - Approval Require. This Policy determines what information researchers are allowed to make public from their submitted bug reports. For more information about the category selected, please refer to our Responsible Publication page.

Primacy of Impact vs Primacy of Rules

Strike Finance adheres to the Primacy of Rules, which means that the whole bug bounty program is run strictly under the terms stated in this page.

Proof of Concept (PoC) Requirements

A PoC, demonstrating the bug's impact, is required for this program and has to comply with the Immunefi PoC Guidelines and Rules.

Known Issue Assurance

Strike Finance commits to providing Known Issue Assurance to bug submissions through their program. This means that Strike Finance will either disclose known issues publicly, or at the very least, privately via a self-reported bug submission.

In a potential scenario of a mediation, this allows for a more objective and streamlined process, in order to prove that an issue is known. Otherwise, assuming the bug report is valid, it would result in the report being considered as in-scope, and due a reward.

Previous Audits

Strike Finance completed audit reports can be accessed on https://skynet.certik.com/projects/strikefinance for reference. Any unfixed vulnerability mentioned in these reports are not eligible for a reward.

Feasibility Limitations

The project may be receiving reports that are valid (the bug and attack vector are real) and cite assets and impacts that are in scope, but there may be obstacles or barriers to executing the attack in the real world. In other words, there is a question about how feasible the attack really is. Conversely, there may also be mitigation measures that projects can take to prevent the impact of the bug, which are not feasible or would require unconventional action and hence, should not be used as reasons for downgrading a bug's severity.

Therefore, Immunefi has developed a set of feasibility limitation standards which by default states what security researchers, as well as projects, can or cannot cite when reviewing a bug report.

Immunefi Standard Badge

By adhering to Immunefi’s best practice recommendations, Strike Finance has satisfied the requirements for the Immunefi Standard Badge.

Rewards are distributed according to the impact of the vulnerability based on the 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 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 10 000 is to be rewarded in order to incentivize security researchers against withholding a 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 can not 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 of USD 10 000. 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 USD 15 000 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 USD 5 000. The rest of the severity levels are paid out according to the Impact in Scope table.

Reward Payment Terms

Payouts are handled by the Strike Finance team directly and are denominated in USD. However, payments are done in STRK.

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.

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.

These impacts are out of scope for this bug bounty program.

All Categories:

• Impacts requiring attacks that the reporter has already exploited themselves, leading to damage
• Impacts caused by attacks requiring access to leaked keys/credentials
• Impacts caused by attacks requiring access to privileged addresses (governance, strategist) except in such cases where the contracts are intended to have no privileged access to functions that make the attack possible
• Impacts relying on attacks involving the depegging of an external stablecoin where the attacker does not directly cause the depegging due to a bug in code
• Mentions of secrets, access tokens, API keys, private keys, etc. in Github will be considered out of scope without proof that they are in-use in production
• Best practice recommendations
• Feature requests
• Impacts on test files and configuration files unless stated otherwise in the bug bounty program

Smart Contract Specific:

• Incorrect data supplied by third party oracles
  • Not to exclude oracle manipulation/flash loan attacks
• Impacts requiring basic economic and governance attacks (e.g. 51% attack)
