You were there when Blossom Labs opened its first Hacker House. Two days in Cannes during EthCC [9], three events, one house full of builders. You wrote and simulated EVM transactions with AI through EVMcrispr, hunted scattered tokens with Octocash where it first learned to swim, or crafted your (E)therian mask among people who still build like Ethereum was supposed to be built, permissionless, with love. This POAP marks the first iteration: the proof that you showed up, picked up a tool, and found your pack.

The Ethereum Community Conference (EthCC) is the largest and longest-running annual European Ethereum event focused on technology and community. Four intense days of conferences, networking and learning. 𝙋𝙖𝙡𝙖𝙞𝙨 𝙙𝙚𝙨 𝙁𝙚𝙨𝙩𝙞𝙫𝙖𝙡𝙨 𝘾𝙖𝙣𝙣𝙚𝙨, 𝙁𝙍
