StarkNet

StarkNet is a validity rollup based on zk-STARK proofs. It operates as an L2 network over Ethereum, enabling any dApp to achieve scale for its computation – without compromising Ethereum's composability and security.

Rewards by Threat Level

Blockchain/DLT
Critical
USD $40,000 to USD $500,000
High
USD $30,000
Smart Contract
Critical
USD $50,000 to USD $1,000,000
High
USD $30,000

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 smart contract 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 Blockchain/DLT 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 40 000 and a maximum reward of USD 500 000.

StarkNet requires KYC to be done for all bug bounty hunters submitting a report and wanting a reward. The information needed is a full legal name, residential address, date of birth and copy of national ID\ passport. Bounty hunters must pass OFAC Screening. Rewards cannot be paid out if hunters are on the OFAC SDN list and/or do not complete the KYC.

The following person(s) are ineligible to receive bug bounty payout rewards: StarkWare Staff, Auditors and Contractors engaged by StarkWare, persons in possession of privileged information, and any other associated parties.

Payouts are handled by the StarkNet team directly and are denominated in USD. However, payouts are done in USDC.

Program Overview

StarkNet is a validity rollup based on zk-STARK proofs. It operates as an L2 network over Ethereum, enabling any dApp to achieve scale for its computation – without compromising Ethereum's composability and security.

StarkNet is currently still in “alpha” stage. For more information about StarkNet, please visit https://starknet.io/ and https://docs.starknet.io/.

KYC required

The submission of KYC information is a requirement for payout processing.

Prohibited Activities

Default 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.
