Uniswap the DEX and the DeFi platform on the Ethereum platform is developing each year. Like v4 version is in development and there is an update where the bugs are yet to be fixed. And Unswap wishes to outsource this to the community. And they are arranging the contest through the Cantina security audit contest. This way they would be distributing the rewards for the users who are helping build platform bugs. 

This contest is about to happen in the first or the 2nd week of the September. So the week is going to be making some move in the security and bug fixing through the bounty method. So for that they make use of the cantina.xyz. And slowly this is a good direction that is being taken for Uniswap. 

If you are interested then don't forget to check the cantina.xyz website. And you would find the Uniswap security bug competition listed there in the upcoming times.
