# Bug Bounty

Itheum is a fully open source, omni-chain protocol that's powered by multiple open source smart contracts and dapps.

A bug bounty program is being put into place to enable social developers and engineers to responsibly disclose security issues in exchange for a reward.

## Rewards by Threat Level

Rewards are distributed according to the impact of the vulnerability based on the [Immunefi Vulnerability Severity Classification System V2.3.](https://immunefi.com/immunefi-vulnerability-severity-classification-system-v2-3/) 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 bug reports must include a Proof of Concept (PoC) demonstrating how the vulnerability can be exploited to impact an asset-in-scope to be eligible for a reward. Critical and High severity bug reports should also include a suggestion for a fix. Explanations and statements are not accepted as PoC and code is required.

Payouts are handled by the **Itheum** team directly and are denominated in USD. However, payouts are done in **ITHEUM**.

## Rewards

The reward amounts are being finalized, but reach out to us **<bugbounty@itheum.io>** in the meantime for reward amount specifics.&#x20;

## Out of Scope & Rules

**The following vulnerabilities are excluded from the rewards for this bug bounty program:**

* Attacks that the reporter has already exploited themselves, leading to damage
* Attacks requiring access to leaked keys/credentials
* Attacks requiring access to privileged addresses

**Smart Contracts and Blockchain**

* Basic economic governance attacks (e.g. 51% attack)
* Lack of liquidity
* Best practice critiques
* Sybil attacks
* Centralization risks

**The following activities are prohibited by this bug bounty program:**

* Any testing with mainnet or public devnet contracts; all testing should be done on private testnets
* 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
* Automated testing of services that generates significant amounts of traffic
* Public disclosure of an unpatched vulnerability in an embargoed bounty

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.itheum.io/product-docs/pre-aithra/pre-aithra-developers/security/bug-bounty.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
