# Security

## Audits

* THENA V1 has been audited by [PeckShield](https://github.com/peckshield/publications/tree/master/audit_reports/PeckShield-Audit-Report-Thena-v1.0.pdf).
* THENA V2 has been audited by [OpenZeppelin](https://blog.openzeppelin.com/retro-thena-audit).
* THENA V3 (including veTHE automation) has been audited by [Hackken](https://hacken.io/audits/thena/).
* THENA is Real-Time protected by [Hypernative](https://www.hypernative.io/).
* [Algebra Integral Audits](https://docs.algebra.finance/algebra-integral-documentation/algebra-integral-technical-reference/audits).

THENA was originally adapted from Velodrome codebase, which is directly derived from the Solidly smart contracts that have been open sourced in March 2022.\
\
The AMM part of Solidly has been audited by PeckShield that revealed 5 low-severity and 1 informal findings. There have been no security-related incidents involving Solidly smart contracts since their deployment on Fantom in February 2022.

The Velodrome codebase went through a security audit and a peer review as part of a Code4rena bug bounty contest. All high or medium risk issues were either resolved pre-deployment, except for one known issue (users can claim eligible rewards from ExternalBribe contracts more than once) that has been addressed via a wrapped contract solution.
