Neo is a distributed network which utilizes blockchain technology and digital identity to digitize assets and automate the management of digital assets using smart contracts. Neo network has two tokens, NEO representing the right to manage Neo blockchain and GAS representing the right to use the Neo Blockchain.

Issues leading to severe asset loss

Issues leading to total network failure

Single node failure

Any other low (OWASP) issue

Bounties are paid out after a risk assessment ([OWASP risk rating methodology](https://www.owasp.org/index.php/OWASP_Risk_Rating_Methodology)) has been made by the Neo DAU team. There are four rates of severity, Critical, High, Medium, Low. All rewards will be paid in the equivalent amount of NEO. Roughly speaking, we calculate the severity of an issue with the following formula:

Severity = Impact * Likelihood
Base bounty amounts related to severity are as follows:

| Vulnerability Severity | Bounty | Example |
| :-- | :-: | --: |
| **Critical** | Up to $10,000 | Issues leading to severe asset loss | 
| **High** | Up to $5,000 | Issues leading to total networks failure |
| **Medium** | Up to $2,000 | Single node failure |
| **Low** | Up to $500 | Other valid issues |

To be eligible for a reward, bug bounty hunters must never attempt to access anyone else's data and do not engage in any activity that would be disruptive or damaging to the Neo production network and testing network, you can investigate with your own built private chain on a private network. The full rules of the bug bounty program can be found further below, which need to be followed. 

All bug reports must include the following in the report:
  - Asset - What software asset the vulnerability is related to (e.g. Neo core software/products)
  - Severity - Your opinion on the severity of the issue (e.g. high, moderate, low)
  - Summary - Add a summary of the vulnerability
  - Description - Any additional details about this vulnerability
  - Steps - Steps to reproduce, getting Neo staff or technical team clearly informed of every detailed step.
  - Supporting Material/References - Source code to replicate, list any additional material (e.g. screenshots, logs, etc.)
  - Impact - What security impact could an attacker achieve?
  - Your name and country.

Neo may require more KYC information to be submitted over the Immunefi bug reporting dashboard at its discretion.
