### Thanks to everyone who participated in the CTF!

Over 300 searchers registered and 61 managed to capture one, or more flags. All addresses that captured a flag will receive a commemorative [chest of gold](https://opensea.io/collection/flashbots-ctf-winner?search%5BstringTraits%5D%5B0%5D%5Bname%5D=CTF%20Reward&search%5BstringTraits%5D%5B0%5D%5Bvalues%5D%5B0%5D=Chest%20of%20Gold). To celebrate a couple of searchers that surprised and impressed us we’ve also created a set of [special badges](https://opensea.io/collection/flashbots-ctf-winner?search%5BstringTraits%5D%5B0%5D%5Bname%5D=CTF%20Reward&search%5BstringTraits%5D%5B0%5D%5Bvalues%5D%5B0%5D=Pirate&search%5BstringTraits%5D%5B0%5D%5Bvalues%5D%5B1%5D=FOSS&search%5BstringTraits%5D%5B0%5D%5Bvalues%5D%5B2%5D=Scribe&search%5BstringTraits%5D%5B0%5D%5Bvalues%5D%5B3%5D=Spy&search%5BstringTraits%5D%5B0%5D%5Bvalues%5D%5B4%5D=Victory).

The NFTs are all non-transferrable, burnable, and awarded on Goerli + mainnet.

### What next?

You can use your CTF bots to keep searching on MEV-Share. Just swap the endpoints to[http://mev-share.flashbots.net](https://t.co/Pk1Yi7eCxk) /[http://relay.flashbots.net](https://t.co/FvsCsRtRcD) to start backrunning real transactions on mainnet.

If you’re new to MEV, take a look at [the example bots and guides](https://docs.flashbots.net/flashbots-mev-share/searchers/tutorials/limit-order/more-resources) for how to update your strategy.
