Stader provides rewards in USDC. For more details about the payment process, please view the Rewards by Threat Level section further below.

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.

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.

All code of Stader can be found at https://github.com/stader-labs/ethx/tree/mainnet_V0/contracts. Documentation for the assets provided in the table can be found at https://staderlabs.gitbook.io/ethereum/.

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 Contracts and Blockchain/DLT

• Incorrect data supplied by third party oracles
  • Not to exclude oracle manipulation/flash loan attacks
• Impact of future improper configuration of contracts that are not deployed
• 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
