Rewards by Threat Level
Rewards are distributed according to the impact of the vulnerability based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale, with separate scales for websites/apps, smart contracts, and blockchains/DLTs, focusing on the impact of the vulnerability reported.
All bug reports must come with a PoC with an end-effect impacting an asset-in-scope in order to be considered for a reward. Explanations and statements are not accepted as PoC and code is required.
Rewards for critical smart contract vulnerabilities are further capped at 10% of economic damage, with the main consideration being the funds affected in addition to PR and brand considerations, at the discretion of the team. However, there is a minimum reward of USD 50 000 for Critical smart contract bug reports.
Previous issues highlighted in the following audit reports are considered out of scope of this program:
Payouts are handled by the Stader team directly and are denominated in USD. However, payouts are done in USDC or ETH, at the discretion of the team.
- USD $50,000 to $250,000
- USD $15,000 to USD $50,000
- Up to USD $15,000
Assets in scope
- Smart Contract - StakeManager ContractType
- Smart Contract - BNBx token BEP20Type
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.
All smart contracts of Stader for BNB can be found at https://github.com/stader-labs/bnbX. However, only those in the Assets in Scope table are considered as in-scope of the bug bounty program.
If any Critical/High severity impact can be caused to any other asset managed by Stader for BNB that isn’t on this table but for which the impact is in the Impacts in Scope section below, you are encouraged to submit it for the consideration by the project.
