In this challenge, we need to fing the Ethereum address of the artist of an NFT called blanc avec des liserés blancs transversaux.
First I tried looking some websites that host NFTs. I found OpenSea. I search the NFT name but didn’t find anything interesting… At least that’s what I thought at the beginning when I saw those NFTs:
But if we take a closer look, and click on one of them, we notice that the collection name is indeed blanc avec de fins liserais blancs transversaux that is quite similar to blanc avec des liserés blancs transversaux:
As we can see in the above screenshot, we can find the owner Antrios by clicking on its name:
And that’s how we found its Ethereum address and so the flag is 404CTF{0xD7186D588Ed2AddF8b260d09B108100f264A64A9}.
