ZeroLiquid provides you self-repaying, 0% interest, non-liquidation loans for your liquid staking tokens.
For more information about ZeroLiquid, please visit https://zeroliquid.xyz/
ZeroLiquid provides rewards in ETH and ZERO, the native token of ZeroLiquid. For more details about the payment process, please view the Rewards by Threat Level section further below.
ZeroLiquid adheres to category 3. This Policy determines what information whitehats 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
ZeroLiquid adheres to the Primacy of Impact for the following impacts:
- Smart Contract - Critical
- Smart Contract - High
If an impact is covered within the Primacy of Impact, it means that even if the impacted asset is not in-scope but is owned by the project, then it would be considered as in-scope of the bug bounty program. When submitting a report, just select the Primacy of Impact asset placeholder. If the team behind this project has multiple projects, those other projects are not covered under the Primacy of Impact of this program. Instead, check if those other projects have a bug bounty program on Immunefi.
All other impacts are considered under the Primacy of Rules, which means that they are bound by the terms of the bug bounty program.
Known Issue Assurance
ZeroLiquid commits to providing Known Issue Assurance to bug submissions through their program. This means that ZeroLiquid will either disclose known issues publicly or at the very least privately via a self-reported bug submission in order to allow for a more objective and streamlined mediation process to prove that an issue is known. Otherwise, assuming the bug report itself is valid, it would result in the bug report being considered in-scope and due 100% of the reward with respect to the bug bounty program terms.
Immunefi Standard Badge
ZeroLiquid has satisfied the requirements for the Immunefi Standard Badge, which is given to projects that adhere to our best practices
Rewards by Threat Level
Rewards are distributed according to the impact the vulnerability could otherwise cause based on the Impacts in Scope table further below.
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 40 000. 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
In cases of repeatable attacks for smart contract bugs, only the first attack will be counted, regardless of whether the smart contract is upgradable, pausable, or killable.
Public Disclosure of Known Issues
Bug reports covering previously-discovered bugs acknowledged below are not eligible for any reward through the bug bounty program.
- All vulnerabilities listed here:
- All vulnerabilities listed in Runtime Verification audit
- All vulnerabilities listed in BlockApex audit
ZeroLiquid has provided these completed audit review reports for reference. Any unfixed vulnerability mentioned in these reports are not eligible for a reward.
Proof of Concept (PoC) Requirements
A PoC is required for the following severity levels:
- Smart Contract + Critical + PoC Required
- Smart Contract + High + PoC Required
- Smart Contract + Medium + PoC Required
All PoCs submitted must comply with the Immunefi-wide PoC Guidelines and Rules. Bug report submissions without a PoC when a PoC is required will not be provided with a reward.
Other Terms and Information
Though only the proxy contracts are listed as in-scope, current implementation and any further updates to the implementation contracts are considered in scope. When reporting a bug, please make sure to select the relevant proxy smart contract as the target.
Reward Payment Terms
Payouts are handled by the ZeroLiquid team directly and are denominated in USD. The payment scheme involves two forms of currency: Ether (ETH) and ZeroLiquid Token (ZERO). 50% of the total payout is made in Ether, while the remaining 50% is made in ZeroLiquid Token.
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. For avoidance of doubt, if the reward amount is USD 5 000 and the average price is USD 1.75 per token, then the reward will be 2857.142857 units of that token.
- USD $10,000 to USD $40,000

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.
- Direct theft of any user funds, whether at-rest or in-motion, other than unclaimed yieldCriticalImpact
- Permanent freezing of fundsCriticalImpact
- Protocol insolvencyCriticalImpact
- Theft of unclaimed yieldHighImpact
- Permanent freezing of unclaimed yieldHighImpact
- Smart contract unable to operate due to lack of token fundsMediumImpact
- Griefing (e.g. no profit motive for an attacker, but damage to the users or the protocol)MediumImpact
- Unbounded gas consumptionMediumImpact
- Miner-extractable value (MEV)MediumImpact
Out of Scope & Rules
These impacts are out of scope for this bug bounty program.
- 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 Contracts and Blockchain/DLT
- 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)
- Lack of liquidity impacts
- Impacts from Sybil attacks
- Impacts involving centralization risks
- Best practice recommendations
The following activities are prohibited by this bug bounty program:
- Any testing on mainnet or public testnet deployed code; all testing should be done on local-forks of either public testnet or mainnet
- 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 that are executed against project assets
- Automated testing of services that generates significant amounts of traffic
- Public disclosure of an unpatched vulnerability in an embargoed bounty
