How I almost won an NFT that worth $3000 on an Easter Egg Challenge

5 days ago the Chef Rabbit Doge and the PancakeSwap team created a first public sale of 10,000 unique PancakwSquad NFTs.

The sale was successful and after 10 seconds all the NFTs have been bought for 300$ each buy different wallets and users.

The next day, the Chef Rabbit Doge (from the PancakeSwap team), announced in his Twitter account that there is a secret easter egg inside the PancakeSquad NFTs, and the one who finds it will get a gift.

I was excited about it because I love those kinds of CTF's (Capture The Flag) challenges, and I start looking at the PacnakwSwap NFTs in order to find the easter egg.

I've made a complete walkthrough of how I approached the challenge and solved it, and how I ALMOST won an NFT that was worth $3,000.

First I looked on the website itself, and I couldn't find anything. The next step was to look at the blockchain itself through bscscan.

I analyzed 2 smart contracts (PancakeSquad contract and NFTSale contract), I looked at the code and the first transactions that were sent by the deployer, but again, I couldn't find anything.

Then, I thought that the answer might be on the resources themselves (NFT Data and pictures), so using python I scraped all the NFTs JSON files and I downloaded all the pictures, but it was a lot of work to manually check them one by one.

I was able to directory list the folder inside the IPFS and then I found a different picture named "MissingNO.png".

When I opened the image in a text editor I was able to find encoded reversed message inside a huge PancakeSwap ASCI art ;) After fixing the test you can find a story that contains a seed phrase that gives you access to a wallet that contains the last missing NFT (The gift was a PancakeSquad unique NFT).

I enjoyed the challenge very much and learned a lot of new things, I decided to make this guide and share my experience with you guys so you can learn as well.

Did you participate in the challenge?

What do you think about the video?
