# Audits

At Ethena, the integrity of our smart contracts is paramount. We maintain this by conducting comprehensive audits, which help identify potential vulnerabilities, logical errors, or inefficiencies. These rigorous audits, carried out by industry experts, fortify our security and seek to increase trust in the platform. 

### Approach to Audits

Ethena has undertaken a multi-phased audit program to ensure the highest level of security on the procotol.

**Phase 1:** conducted initial audit with Zellic on the v1 of the protocol where no critical or high level vulnerabilities were found.\
\
**Phase 2**: architecture design review and economic risk factor analysis with [Spearbit](https://spearbit.com/)'s [Kurt Barry](https://twitter.com/Kurt_M_Barry) former Lead Engineer at MakerDAO

**Phase 3:** phased audit with industry leading firms:\
\
-[Quantstamp](https://quantstamp.com/)\
-[Spearbit](https://spearbit.com/) & [Cantina](https://cantina.xyz/welcome)\
\
**Phase 4:** independent audit with [Pashov](https://twitter.com/pashovkrum) with individual experience of over 50 audits

**Phase 5:** public audit with [Code4rena](https://code4rena.com/) 

**Phase 6:** economic and financial risk audit by [Chaos Labs](https://chaoslabs.xyz/)
