Ledger Op3n Replay Buenos Aires: Self-Custody, Community, and the Future of Web3 at Devconnect

The conference made it clear that Argentina is more than just an adopting market: it is a leader in self-custody and in the evolution of decentralized finance

As part of Devconnect 2025, Buenos Aires once again became the meeting point for Web3 developers and advanced users. There, Ledger—a global leader in security and self-custody—organized its Ledger Op3n Replay Buenos Aires, an experience designed to listen to the local community and share the company's latest innovations.

The proposal was clear: to discuss self-custody with those who practice it every day in a country that experiences crypto in a real, everyday way.

Carl Anderson focused on security, which can be read

The event was hosted by Carl Anderson, VP of Engineering at Ledger, who gave a straightforward presentation on the technologies that seek to raise the security standard in Web3:

Clear Signing  Allows you to clearly read what you are signing before approving any transaction. No more "accept and trust."

Better technical experience  Greater connectivity between Ledger devices and decentralized applications.

Architecture ready for the future  Designed for new use cases, protocols, and interaction models.

A technical and collaborative space with the Argentine community

Ledger Replay allowed attendees to engage directly with the engineering team in an informal and participatory format that lasted throughout the afternoon and evening.

This facilitated:

• high-level technical discussions

• direct feedback on the real needs of the Argentine market

• a more accurate interpretation of the role of cryptocurrency as a tool for economic access and protection

The conference made it clear that Argentina is more than just an adopting market: it is a leader in self-custody and in the evolution of decentralized finance. Ledger reaffirmed that it will continue to support the community with education, technology, and proximity, because the future of Web3 is built where users are in control of their security.

A global fund within reach of Latin American entrepreneurs

In addition, Ledger has its own investment fund, Cathay Innovation — Ledger Cathay Capital — with €100 million earmarked to support early-stage Web3 projects (Seed and Series A) globally. Ledger+1This fund represents an open door for Latin American entrepreneurs building Web3 infrastructure, products, or services: not only with financial backing, but also with access to Ledger's global ecosystem of security, technical know-how, and distribution networks.

With this commitment, Ledger not only offers products: it offers opportunity. A strategic commitment to security, innovation, and the sustainable development of the ecosystem in the region.
