We met at EthCC [9] or one of the side events. corpus.core builds blockchain core technology for Ethereum and other L1s and L2s. With the colibri.stateless, we develop a Trustless Stateless Client for Ethereum and other EVM Chains (and more). Any on-chain information can be verified and validated by trustless proofs. No sync is needed, no state is stored. Never again simply trust data from any RPC provider. Colibri.stateless is so tiny that it runs on any IoT hardware, mobile, and web apps, etc. DON'T TRUST. VERIFY! We love to connect with you to support integration in your dApp or extend colibri.stateless to your ecosystem. This is how blockchain access is meant to be.

Holding this digital collectible is proof that we shared some time together during EthCC[9], Cannes 2026. I hope we meet again in the not so distant future but until then, feel free to connect with me on the following platforms: https://t.me/CardnoNFT https://www.linkedin.com/in/matthew-l-cardno/

I passed through Frankfurt Airport in Frankfurt, Germany and I got to mint this pretty POAP! Frankfurt Airport handles flights to over 280 destinations in about 90 countries during peak seasons. It is also Europe’s busiest airport by cargo volume, making it a major freight hub. This POAP was minted in Q4, 2025 as part of a campaign to offer precious collectibles to travellers at 18 airports around the world.

This POAP was given to attendees at the Spark A1 Booth in the Collectibles District, Devconnect ARG. Holding this digital collectible is onchain proof of you meeting the team, learning about AI-powered Web3 development, and creating something onchain with us during Devconnect in Buenos Aires.

You attended the Nouns Fair! See you at the next edition; in the meantime, keep building! Stay Nounish ⌐◨-◨
