Nodle / Nodle bounty

Introduction

The Nodle Network is a decentralized wireless network, composed of Nodle Edge Nodes, powered by the Nodle Chain, and the NODL token. Nodle connects the physical world to Web3 by using smartphones as edge nodes. The edge nodes read devices and sensors in the physical world using Bluetooth Low Energy (BLE) and connect that information to the blockchain. Creating a geolocation-based layer one that can be used by many unique applications built for the hyper-connected, mobile-oriented world we live in. Nodle creates an economic model that is secure, private, and scalable.

Nodle also develops the Click Camera, a unique solution to authenticate pictures using C2PA, a standard from Adobe, and NFTs.

Impacts only apply to assets in active use by the project like contracts on mainnet or web/app assets used in production. Any impact that applies to assets not in active use, like test or mock files, are out-of-scope of the bounty program unless explicitly mentioned as in-scope.

Out-of-Scope Targets:

Prohibited Actions

No Unauthorized Testing on Production Environments:
Do not test vulnerabilities on mainnet or public testnet deployments without prior authorization. Use local test environments or private test setups.
No Public Disclosure Without Consent:
Do not publicly disclose details of any vulnerability before it has been addressed and you have received written permission to disclose.
No Exploitation or Data Exfiltration:
Do not exploit the vulnerability beyond the minimum steps necessary to demonstrate the issue. Do not access private data, engage in social engineering, or disrupt service.
No Conflict of Interest:
Individuals currently or formerly employed by Nodle Network, or those who contributed to the development of the affected code, are ineligible to participate.

Disclosure Requirements

Reports must incude:

A clear description of the vulnerability and its impact.
Steps to reproduce the issue, ideally with a proof of concept.
Details on the conditions under which the issue occurs.
Potential implications if the vulnerability were exploited.

Reports should be made as soon as possible—ideally within 24 hours of discovery.

Eligibility

To be eligible for a reward, you must:
- Be the first to report a previously unknown, non-public vulnerability within scope.
- Provide sufficient information to reproduce and fix the issue.
- Not have exploited the vulnerability in a malicious manner.
- Not have disclosed the vulnerability to third parties prior to receiving permission.
- Comply with all Program rules and applicable laws.

You must also be of legal age in your jurisdiction and not reside in a country under sanctions or restrictions, as required by applicable laws.

Severity and Rewards

Vulnerabilities are classified using two factors: Impact and Likelihood. The combination of these factors determines the severity and guides the reward amount.

Risk Classification Matrix

Severity Level	Impact: Critical	Impact: High	Impact: Medium	Impact: Low
Likelihood: High	Critical	High	Medium	Low
Likelihood: Medium	High	High	Medium	Low
Likelihood: Low	Medium	Medium	Low	Informational

Impact Definitions:

Critical: Vulnerabilities that can lead to severe loss of user funds, permanent system disruption, or widespread compromise.
High: Vulnerabilities that cause notable financial loss or significantly harm user trust, but on a lesser scale than Critical.
Medium: Vulnerabilities that lead to limited financial damage or moderate system impact.
Low/Informational: Findings that pose minimal direct risk but reflect areas for improvement or best practices.

Likelihood Definitions:

High: Very easy to exploit or highly incentivized.
Medium: Exploitation is possible under certain conditions.
Low: Difficult to exploit or requires highly specific conditions.

Payout Guidelines

Blockchain

Risk Score	Payout Range
Critical	$10,000 - $20,000 USD, $NODL
High	$2,000 - $10,000 USD, $NODL

Rewards for critical Blockchain vulnerabilities are further capped at 10% of the funds at risk. In cases of repeatable attacks, only the first attack is considered unless the smart contract cannot be upgraded or paused. However, there is a minimum reward of $10,000 for Critical Blockchain/DLT bug reports.

Rewards for high Blockchain vulnerabilities are further capped at 100% of the funds at risk. In cases of repeatable attacks, only the first attack is considered unless the smart contract cannot be upgraded or paused. However, there is a minimum reward of $2,000 for High Blockchain/DLT bug reports.

Web Interface / Frontend

Risk Score	Payout Range
Critical	$4,000 - $10,000 USD, $NODL
High	$1,000 - $4,000 USD, $NODL

Rewards for critical web/app vulnerabilities will be further capped at 10% of direct funds at risk if the bug discovered is exploited. However, there is a minimum reward of $4,000.

High web/app vulnerabilities will be further capped at up to 100% of the funds affected. However, there is a minimum reward of $1,000.

Note: Actual reward amounts are determined at Nodle Network’s sole discretion. Factors influencing payout include quality of report, completeness, and the severity and exploitability of the vulnerability.

Out of Scope

Category	Specific Vulnerabilities and/or Attacks to be Excluded
Website & Application	Attacks with the potential to disrupt other customers of a shared web hosting environment, such as but not limited to Vercel.
Website & Application	Attacks that purposefully access account-related data that belongs to another user, and was not created for explicit purposes of security investigation.
Website & Application	Attacks relying on the user installing other applications on their smartphone.

Blockchain/DLT	Attacks with the potential to disrupt other customers of a shared hosting environment such as OnFinality, SubQuery, or Alchemy.
Blockchain/DLT	Attacks that purposefully access account-related data that belongs to another user, and was not created for explicit purposes of security investigation.
Blockchain/DLT	Vulnerabilities affecting third-party services used by Nodle such as OnFinality.

Other Terms

By submitting a report, you grant Nodle Network the rights necessary to investigate, mitigate, and disclose the vulnerability. Reward decisions and eligibility are at the sole discretion of Nodle Network. The terms, conditions, and scope of this Program may be revised at any time. All participants are responsible for reviewing the latest version before submitting a report.
