Reward Distribution

Please review how rewards are distributed based on the Immunefi Vulnerability Severity Classification System V2.2. This is a simplified 5-level scale system with separate scales for Smart Contracts and Websites/Apps.

Payouts over the lower bound reward are directly related to the direct funds at risk. If no funds are at risk, the Critical or High payouts are limited to the minimum, unless decided otherwise by Polygon Labs.

For the purposes of clarification, funds at risk refer to the proof of loss of funds.

Rewards for critical blockchain/DLT and smart contract bug reports will be further capped at 10% of direct funds at risk if the bug discovered is exploited. However, there is a minimum reward of USD 50 000.

Payouts and Payout Requirements

Payouts are handled by the Polygon Labs team directly and are denominated in USD. Payouts are done in USDC or MATIC at the Polygon Labs teams' discretion. Polygon Labs commits to honoring payouts according to the terms set out in this program at the time of report submission, and to treat this program as the agreement and source of truth concerning bug reports and responsible disclosures.

This bug bounty program is only open to individuals who reside outside of the countries that are restricted by OFAC and by UNSC resolutions. If the individual is a US person, tax information may be required in order to properly issue a 1099.

For the purposes of determining report validity, this is a Primacy of Impact program.

KYC Requirements

Polygon Labs does have a Know Your Customer (KYC) requirement for bug bounty payouts.

KYC Info Required
Wallet Address
Passport (for Critical payouts)
Place of residence (for Critical payouts)

KYC information is only required on confirmation of the validity of a bug report which Polygon Labs determines in its sole discretion.

Responsible Publication

Polygon zkEVM 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.

Program Overview

Polygon is a Layer 2 scaling solution that achieves scale by utilizing sidechains for off-chain computation and a decentralized network of Proof-of-Stake (PoS) validators.

Polygon strives to solve the scalability and usability issues while not compromising on decentralization and leveraging the existing developer community and ecosystem. It aims at improving existing platforms by providing scalability and superior user experience to dApps and user functionalities.

It is a scaling solution for public blockchains. Polygon PoS supports all the existing Ethereum tooling along with faster and cheaper transactions. For more information about Polygon Labs and Polygon protocols, please visit https://polygon.technology/.

For Whitehats: It is highly recommended that you review the details of this program in full. Although many Bug Bounty programs have standard terms and conditions, each also has their own unique details that are critical to your success.

Prior to submitting a report please review the Immunefi Bug Report Template and Best Practices.

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.
