# Smart Contract Audits

### TL;DR

* A full smart contract audit was performed by [Sec3](https://www.sec3.dev/) on Zeebit's [three core smart contracts](/zeebit.io/technical-overview/smart-contract-structures.md).
* A number of issues were identified which have now been addressed or acknowledged as not posing a risk.
* A subsequent review has been performed by Sec3 to validate the changes implemented to address previously flagged issues.

### Overview

The three Zeebit core smart contracts have undergone an audit by leading web3 security firm, Sec3 (formerly Soteria).
