Stader for ETH
Stader is a non-custodial smart contract based staking platform that helps you conveniently discover and access staking solutions.
PoC required
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 1 000 000. 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 100 000 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.
- SD Auction final bid price can be gamed by MEV optimization. (This is intended)
- Node Operator can avoid small portion of validator penalty by exiting at the right time. (This is limited to once per validator and cost of exiting and reactivation does not justify penalty saved)
- ER update via chainlink may return incorrect or state data as it is not implemented yet, Currently ER data is submitted by oracle members.
- Protocol will not benefit from slashing mechanism when remaining penalty bigger than minThreshold of SD
Previous Audits
Stader 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
- Smart Contract - High
- Smart Contract - Medium
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.
Reward Payment Terms
Payouts are handled by the Stader team directly and are denominated in USD. However, payments are done in USDC.
Program Overview
Stader is a non-custodial smart contract based staking platform that helps you conveniently discover and access staking solutions.

Responsible Publication
Stader 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
Stader adheres to the Primacy of Impact for the following severity levels:
- Smart Contract - Critical
- Smart Contract - High
If a category’s severity level 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 as long as it involves an impact under that respective severity level. 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.
Testnet and mock files are not covered under the Primacy of Impact.
All other severity levels not listed here are considered under the Primacy of Rules, which means that they are bound by the terms of the bug bounty program.
Known Issue Assurance
Stader commits to providing Known Issue Assurance to bug submissions through their program. This means that Stader 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
Stader has satisfied the requirements for the Immunefi Standard Badge, which is given to projects that adhere to our best practices.
KYC not required
No KYC information is required for payout processing.
Prohibited Activities
- 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
- Any other actions prohibited by the Immunefi Rules
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.
