I passed through Ministro Pistarini International Airport in Buenos Aires, Argentina and I got to mint this pretty POAP! Ezeiza is where Argentina’s first international flight departed in 1949—it was inaugurated by President Juan Perón and Eva Perón. This POAP was minted in Q4, 2025 as part of a campaign to offer precious collectibles to travelers at 18 airports around the world.

This POAP was given to the privacy-aware attendees at the Ethereum World Fair 2025 that tested completely private, self-sovereign AI that anyone can run at home at the Dappnode booth

This POAP was given to visitors of the Burner booth held at the Ethereum Worlds Fair. A Burner card wallet is the easiest way to get started on Ethereum. Simply tap Burner to your phone and load funds, swap tokens and save NFTs. Burner uses the same kind of secure element found in expensive hardware wallets but without the hassle of tiny screens or a confusing set up.

This POAP was given to visitors of the Santiment booth held at the November 2025 Ethereum Worlds Fair in Argentina.

Proof of attending Devconnect 2025

We met at DEVCONNECT ARG or one of the side events. corpus.core builds blockchain core technology for Ethereum and other L1s and L2s. COLIBRI.STATELESS is LIVE (PRODUCTION) ON ETHEREUM! 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.
