-# DODO V2: Help 1 Trillion People Issue Token
+# Scope of Audit
 
-## Audit Report
+- contracts/DODOToken/DODOMineV3/
 
-[Audited by Peckshield](https://github.com/DODOEX/contractV2/blob/main/audit/PeckShield-Audit-DODOV2-v1.0.pdf)
+- contracts/Factory/Registries/DODOMineV3Registry.sol
 
-## Bug Bounty 💰
+- contracts/SmartRoute/proxies/DODOMineV3Proxy.sol
 
-### Rewards
+- contracts/external/CustomERC20.sol
 
-Severity of bugs will be assessed under the [CVSS Risk Rating](https://www.first.org/cvss/calculator/3.0) scale, as follows:
-
- - Critical (9.0-10.0): Up to $100,000
- - High (7.0-8.9): Up to $10,000
- - Medium (4.0-6.9): Up to $5,000
- - Low (0.1-3.9): Up to $1,000
-
-In addition to assessing severity, rewards will be considered based on the impact of the discovered vulnerability as well as the level of difficulty in discovering such vulnerability.
-
-### Disclosure
-
-Any vulnerability or bug discovered must be reported only to the following email: contact@dodoex.io; must not be disclosed publicly; must not be disclosed to any other person, entity or email address prior to disclosure to the contact@dodoex.io email; and must not be disclosed in any way other than to the contact@dodoex.io email. In addition, disclosure to contact@dodoex.io must be made promptly following discovery of the vulnerability. Please include as much information about the vulnerability as possible, including:
-
- - The conditions on which reproducing the bug is contingent.
- - The steps needed to reproduce the bug or, preferably, a proof of concept.
- - The potential implications of the vulnerability being abused.
- 
-A detailed report of a vulnerability increases the likelihood of a reward and may increase the reward amount.
-
-Anyone who reports a unique, previously-unreported vulnerability that results in a change to the code or a configuration change and who keeps such vulnerability confidential until it has been resolved by our engineers will be recognized publicly for their contribution, if agreed.
