Greetings, Huffoor! This document will guide you through the steps to solve this challenge and register your solution.
NOTE -- after you submit, if you want to change your Huff code (for example to try and optimize even more) Please remember to retain your original code that matches the hash! The winner's Huff code will be human reviewed and if it doesn't match the Hash you submitted then it will not count.
In a realm where mystical forces and advanced technology coexist, the Lost temple of Ethereum stands as a pinnacle of untold power. Guarded by three sacred gates, the temple's treasures remain a mystery, accessible only to those who prove their worth. The majestic horse Etherion, a guardian crafted from Ether itself, watches over these gates. Etherion will only step aside for adventurer who can solve the three divine challenges that bar the way to the temple's inner sanctum by deciphering the hidden logic and implementing them using Huff.
To aid you in your quest, Etherion directs your gaze to a Mystic Oracle. This Oracle serves as a guide, providing the output to various inputs—clues to decipher the riddles of the gates. Use this wisdom wisely to unlock the secrets of the three gates. Visit the oracle here to contemplate the patterns and, perhaps, unveil the logic hidden within.
Your mission is simple: solve these challenges with the least gas cost to win Etherion's approval, open the sacred gates, and claim the temple's long-hidden treasures.

-
Solve the Puzzle: Dive into the PLAYER_SOLUTION.huff file and work your magic to solve the challenge.
-
Testing: While solving, you can utilize the test suite Solution.t.sol to validate your solution. Feel free to make changes to this file; it won't affect the main challenge or your submission. It's just there to assist you.
Once you're confident in your solution, register it with the HuffCTFRegistry on Optimism mainnet:
- Set Up Your Discord Handle: Before running the registration script, set up an environment variable with your Discord handle (without the '@' symbol):
export PLAYER_HANDLE=devtooligan- Run the Registration Script: Use the following command to run the registration script:
forge script script/Solution.s.sol:Register --rpc-url <OPTIMISM RPC URL> --broadcast -vvvvNote:
- This command sends a live transaction on Optimism. Replace
<OPTIMISM RPC URL>with a valid URL. - You'll need to use an actual wallet for the transaction. You can specify your wallet using the
--walletflag. Alternatively, you can input your private key in other ways, such as by using the--interactiveflag. See Foundry documentation for more information.
Also note:
- You can also interact directly with the Optimism block explorer. This is not the recommended way due to the danger of human error. If you want to see the exact input parameters you can run the Register script above and DO NOT use a private key. The arguments will be console.logged for you.
!!!Very important -- after you submit, if you want to change your Huff code (for example to try and optimize even more) Please remember to retain your original code that matches the hash! The winner's Huff code will be human reviewed and if it doesn't match the Hash you submitted then it will not count.
That's all there is to it! Once the challenge concludes, feel free to make your repository public. If your solution ranks among the top contenders, it will undergo a human review. Stay updated by keeping an eye on our Discord channel and Twitter feed.
Best of luck, and may the best coder win!
