Polygon
Submit a BugProgram 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.
Rewards by Threat Level
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.
Learn more about report validity best practices here: Best Practice - Primacy of Impact vs Primacy of Rules.
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.

The list of all deployed contracts can be found at: https://static.polygon.technology/network/mainnet/v1/index.json
Impacts only apply to assets in active use by the project like contracts on mainnet or web/app assets used in production.
For GitHub repositories please ensure you are reviewing the latest published releases and not the default branch
Any impact that applies to assets not in active use, like test or mock files, are out-of-scope of the bug bounty program unless explicitly mentioned as in-scope. In the case of Smart Contracts, please always make sure the code has been deployed and present in the JSON file on the first row.
Blockchain/DLT
-
Blockchain/DLT - PoC, Blockchain/DLT bug reports are to include a runnable Proof of Concept (PoC) in order to prove impact.
-
For more information on PoCs please visit: Proof of Concept (PoC) Guidelines and Rules
-
Smart Contracts - PoC, Smart Contract bug reports are to include a runnable Proof of Concept (PoC) in order to prove impact.

Impacts in scope
Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table.

Only the following impacts are accepted within this bug bounty program. All other impacts are not considered as in-scope, even if they affect something in the assets in scope table. The final classification however takes into consideration the likelihood of the impact being achieved based on the table below. When submitting a bug report, select the original assigned impact level, but please be aware that its severity level may be reassigned based on the likelihood according to this table.
Impact \ Likelihood | Critical | High | Medium | Low | Informational |
---|---|---|---|---|---|
Critical | Critical | Critical | High | Medium | Informational |
High | High | High | High | Medium | Informational |
Medium | Medium | Medium | Medium | Low | Informational |
Low | Medium/Low | Medium | Low | Low | Informational |
None | Informational | Informational | Informational | Informational | Informational |
In addition to Immunefi’s Vulnerability Severity Classification System, Polygon classifies vulnerabilities using the Common Vulnerability Scoring System (CVSS). In case of discrepancy, final determination is done by Polygon.
Impacts to other assets
Hackers are encouraged to submit issues outside of those outlined Impacts and Assets in Scope.
If Whitehats can demonstrate a critical impact of code in production for an asset not in scope, Polygon Labs encourages you to submit your bug report using the “primacy of impact exception” asset as outlined below.

The following impacts and attack vectors are excluded from rewards by default for all Immunefi bug bounty programs:
- Attacks that the reporter has already exploited themselves, leading to damage
- Attacks requiring access to leaked keys/credentials
- 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
- Broken link hijacking is out of scope
- Loss of funds held by third parties
Smart Contracts and Blockchain/DLT
- Previously known vulnerabilities (resolved or not) on the Ethereum network (and any other fork of these).
- Previously known vulnerabilities in Tendermint and or/any other fork of these.
- Previously known vulnerabilities in cosmos-sdk and or/any other fork of these.
- Basic economic governance attacks (e.g. 51% attack)
- Lack of liquidity
- Best practice critiques
- Sybil attacks
- Centralization risks
- Attacks using vulnerable, old or deprecated libraries, that are not exploitable
