At Cantina, we help protocols keep their code secure by working with the best security researchers in the industry - that’s why Uniswap Labs and Uniswap Foundation have chosen to work with us to secure [v4](https://blog.uniswap.org/uniswap-v4).

This competition is a big one - the biggest in DeFi history in fact - with a prize pool of $2.35M, and covers v4 core contracts, periphery contracts, and the Universal Router. It kicks off on September 4th, 2024, and will run until September 30th, 2024.

## How Cantina Competitions Work

If you’re not familiar with how Cantina Competitions work, researchers can submit issues which are then rewarded based on the severity of the issue disclosed and the quality of the documentation in the submission itself. You can read more on what constitutes a ‘good’ submission [here](https://docs.cantina.xyz/cantina-docs/cantina-competitions/for-security-researchers).

## The Competition Scope

The competition will focus on reviewing contracts and identifying vulnerabilities in the following GitHub repositories:

- [v4 Core Repository](https://github.com/Uniswap/v4-core)
- [v4 Periphery Repository](https://github.com/Uniswap/v4-periphery)
- [Universal Router](https://github.com/Uniswap/universal-router)

If during your investigations you find an issue in other smart contracts that you think poses a risk to user funds, you can make a submission to [Uniswap’s bug bounty program](/bounties/f9df94db-c7b1-434b-bb06-d1360abdd1be) (also on Cantina!).

## Ready to contribute to the security of v4?

You’ll need to sign up as a researcher on Cantina if you haven’t already. The scope, final commit, and all other details of the competition will be found on the v4 Competition Page once it goes live in the coming days. Until then, keep an eye on our [Competitions page](/competitions)!

It’s time to lock in.
