Innovation in Border Controls between IDB and Extrimian

Have you ever wondered how technology can transform customs? Well, here’s an answer! The CADENA Project: a IDB and Extrimian Solution.

The IDB, or Inter-American Development Bank (IDB), in collaboration with Extrimian, is doing exactly that. In this post, let’s dive into this fascinating world of innovation, security and cryptography.

What is the CADENA Project?

The CADENA Project seeks to revolutionize customs processes towards greater efficiency and transparency. And how does it do that? Through decentralized technology, facilitating trade and strengthening trust in global supply chains – it’s an innovative answer to the challenges of international trade!

The Extrimian’s Role in the CADENA project

Extrimian collaborates closely with the IDB and together they have recently made significant progress:

Creation and management of Decentralized Identifiers (DIDs) and Verifiable Credentials (VCs).
Development of an intuitive user interface to manage Authorized Economic Operators (AEOs) registries.
Implementation of different roles and permissions, ensuring proper access and configuration.
Automatic generation of cryptographic keys and secure synchronization between customs offices.
Efficient management of Mutual Recognition Agreements (MRAs).
Simplified processes for agile deployment, despite complex technological infrastructure.

Benefits and Potential Impact

The implementation of CADENA can be a game changer in international trade. It will facilitate the adherence of more customs to the network, promoting fairer, safer and more transparent trade.

Next Steps and Validation

The IDB and Extrimian are not stopping here. Next steps include:

Testing in real environments and gathering feedback.
Implementation for information exchange through Verifiable Credentials (VCs).
Ongoing pilot testing with selected customs and authorized economic operators.


The CADENA Project is a pioneering initiative that marks a before and after in the customs administrations of Latin America and the Caribbean. With the IDB and Extrimian we are witnessing a true revolution in international trade. Stay tuned for more news!


CADENA Project:

Initiative promoted by the Inter-American Development Bank (IDB) and Extrimian, designed to transform customs administrations in Latin America and the Caribbean through decentralized technologies.

Inter-American Development Bank (IDB):

International financial organization that supports projects in Latin America and the Caribbean, focusing on economic, social and institutional development.


Technology company that collaborates with the IDB in the CADENA Project, specialized in cryptography and digital identity solutions.

Decentralized Technology:

Technology that operates in a distributed network, rather than being centralized in a single location or server. This can include blockchain and other forms of distributed technology.

Decentralized Identifiers (DIDs):

Digital identification systems that enable secure, decentralized online identity verification.

Verifiable Credentials (VCs):

Digital documents that can be used to verify the authenticity of an identity or related information in a secure and reliable manner.

Authorized Economic Operators (AEOs):

Commercial entities that have been certified by national or international authorities as secure and reliable in the supply chain.

Cryptographic Keys:

Tools used in cryptography to secure communication and information, allowing data encryption and decryption.

Mutual Recognition Arrangements (MRAs): Agreements between countries or regions that facilitate trade by recognizing each other’s security and conformity assessments.

Pilot Testing:

Experimental tests conducted to evaluate the feasibility, performance and effectiveness of a new project or system prior to its full implementation.
