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. 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 a lot the challenge 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. ___________________________________________________________ Links: PancakeSwap: https://pancakeswap.finance/ Chef Rabbit Doge Twitter: https://twitter.com/chefrabbitdoge PancakeSquad Smart Contract: https://bscscan.com/address/0x0a8901b0E25DEb55A87524f0cC164E9644020EBA NFTSale Smart Contract: https://bscscan.com/address/0x29fE7148636b7Ae0b1E53777b28dfbaA9327af8E Open IPFS links as HTTPS: https://docs.ipfs.io/how-to/address-ipfs-on-web/ The Hidden Image: https://ipfs.io/ipfs/QmaYTLuEoP35NcBKLsyPMzwDpebbZWukdEkzeGV9fVcUCt/MissingNO.png The Wallet That Contained The Easter Egg: https://bscscan.com/address/0x774b4277a08d4e5c6089d918c5355700d2cee1b5 ___________________________________________________________ ___________________________________________________________ Related Videos: PancakeSwap Getting Started Guide: https://www.youtube.com/watch?v=PG3Ho9gYqMc What Is PancakeSwap: https://www.youtube.com/watch?v=kYLknjBMR ... https://www.youtube.com/watch?v=MaNUsBunU3U
