Thank you for being part of DSS in Buenos Aires! Three days, dozens of talks, countless insights, and an incredible community pushing DeFi security forward. We’re grateful you were part of it.

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

Minting this POAP is proof of your attendance at the trustless:// conference during Devconnect, ARG. trustless:// is where we gathered to affirm that Ethereum’s future is open, censorship-resistant, and above all - trustless. We explored how the Ethereum Interop Layer (EIL), OIF, ERC-4337, and other interop protocols extend these guarantees and more: open mempools, multiple routes to inclusion, and wallets that can evolve permissionlessly.

This POAP was given to attendees who made a Mercado Pago transaction using Peanut during the Devconnect ARG event.

Thank you for stopping by our booth at the Ethereum World’s Fair, Devconnect ARG.

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.

Minting this POAP is proof of your attendance at the Account Abstraction Community Hub during Devconnect, ARG. Thank you for taking part in our shared effort to promote usability and security for users in the Ethereum ecosystem. The AA Community Hub was organised by the ERC-4337 core team and brought to life by numerous companies, groups and individual contributors in the space.

Connect with other builders, talk to teams looking for talent, meet your users, or showcase your app at the Ethereum World’s Fair. Explore what Ethereum is for and what it enables, test applications, and win in some fun challenges.
