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 presents Cruzada21, a coordinated initiative to bootstrap and connect Bitcoin circular economies across Latin America. At its core is VEINTIUNO.LAT, a network of communities designed to overcome two critical bottlenecks: sustained adoption and self-custody at scale.
The first deployment wave includes 10 pilot communities, from Buenos Aires to Berlín (El Salvador). Each receives a Bitcoin full node, 15 POS terminals, and 200 NFC cards. Alongside the hardware, every community is assigned a task force of five specialists led by a captain, responsible for infrastructure setup, merchant onboarding, digital presence (website, branding, social channels), and ongoing operational support.
The backbone of the project is the new LaWallet v2 stack — a modular, open-source architecture for Lightning wallets. It integrates Nostr Wallet Connect (NWC) and Alby Hub, enabling a seamless onboarding flow with progressive custody. New users begin in a custodial environment to simplify entry, while LaWallet provides a path to transparent, verifiable self-custody, including tamper-proof balances, proof-of-funds via Nostr relays, and auditable ledgers. Merchants gain access to instant Lightning settlement, POS terminals, and NFC tap-to-pay using the BoltCard-compatible system.
Cruzada21 is not only deployment but cross-pollination: squads learn from each community, exchange practices, and refine tools. The roadmap: expand from 10 to 2, 100, and 500 communities within 4 years, measuring success by merchants onboarded, sats transacted, and self-custodial users grown.
This is a technical, cultural, and economic crusade. The hyperbitcoinization of Latin America starts with infrastructure, sovereignty, and code.
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.
