Agustin Kassis
Agustín Kassis is a full-stack developer, early Bitcoiner, and entrepreneur committed to hyperbitcoinizing the world. He founded CoinMelon in 2013, one of the first Bitcoin exchanges in Latin America, and launched La Crypta in 2022, now Argentina’s largest and most active Bitcoin community. Rooted in libertarian values, La Crypta promotes Bitcoin adoption through open-source tools, workshops, events, and grassroots engagement, maintaining over 80 repositories focused on Lightning Network, Nostr, and decentralized infrastructure.
He is obsessed with teaching Bitcoin through real-world experience—just like we learned Internet—by providing simple, progressive tools that guide users toward self-custody. From LaWallet—a modular Lightning wallet with tamper-proof balances, POS, and NFC cards—to a Lightning NFC payment system using Android HCE and BoltCard standards, his work makes Bitcoin practical, scalable, and accessible.
He is the founder of Walias.io, a protocol that combines Lightning addresses with Nostr identities, enabling seamless, email-like Bitcoin payments and decentralized identity management. He also leads the Lightning Domains standard, which empowers domain operators to provide Lightning-based identities with features like aliases, badges, spam protection, and plug-and-play integration.
Today, Agustín is driving VEINTIUNO.LAT, a movement to connect and empower grassroots circular Bitcoin economies across Latin America. The initiative provides local communities with full Bitcoin nodes, POS, NFC cards, and onboarding strategies—starting with 10 communities and scaling toward 1000. His mission: accelerate global Bitcoin adoption from the ground up—open-source, permissionless, and unstoppable.
Sessions
La Crypta presents Cruzada21, a crusade to connect and strengthen Bitcoin circular economies across Latin America. We introduce VEINTIUNO.LAT, inspired in TWENTYONE.WORLD, Einundzwanzig initiative.
The first wave begins with 10 communities, from Buenos Aires to Berlín (El Salvador). Each receives a Bitcoin node, 15 POS terminals, and 200 NFC cards. A trained squad of five members led by a captain supports every community: installing infrastructure, creating a website, rebranding, building social presence, and assisting with merchant onboarding.
The deployment relies on the new LaWallet v2 stack, integrating Nostr Wallet Connect (NWC) and Alby Hub, enabling progressive custody onboarding. Users start with a simple custodial experience and transition to full self-custody as they grow.
Our roadmap: 2, 100, 500 communities in 4 years, with clear metrics — onboarded merchants, sats transacted, self-custodial users.
La Crypta presenta Cruzada21: una cruzada para conectar economías circulares de Bitcoin en toda Latinoamérica. Mostramos por qué hace falta VEINTIUNO.LAT —la red que une comunidades para resolver: adopción real y sostenida; y auto-custodia.
Lanzamos con una primera oleada de 10 comunidades, de Buenos Aires a Berlín (El Salvador).
Cada comunidad recibe un nodo, 15 POS y 200 tarjetas NFC.
Se asignó una tropa de 5 con un capitán que se encargan del seguimiento, instalar todo el equipamiento, crear una página web, rebranding, redes sociales y lo que se necesite para difundir la comunidad.
Asistimos en la capacitación a comerciantes, el rol de los artistas para amplificar el mensaje y la polinización cruzada entre territorios.
Roadmap: 2, 100, 500 comunidades en 4 años; métricas (comercios onboardeados, sats, usuarios en autocustodia) y un llamado a sumarse como comunidad, sponsor o voluntario. La Hiperbitcoinización empieza en Latinoamérica.
Presentamos a los 15 valientes soldados.
