Cosmos Labs, Peersyst Technology, and LNET announced a partnership to collaborate on the CBWeb3 Project, a regional initiative funded by IDB Lab to explore Central Bank Digital Currencies (CBDCs) interoperability and tokenized financial assets across Latin America and the Caribbean.
The project brings together more than 10 central banks and financial institutions to assess how digital central bank money can flow across networks while maintaining monetary sovereignty. Cosmos will provide its Inter-Blockchain Communication Protocol (IBC) for cross-network testing.
The CBWeb3 initiative
CBWeb3 aims to develop blueprints for interoperable digital financial infrastructure across the region. The goal is to get central banks on the same page, figuring out how different digital currencies can connect for easier international payments and digital assets.
Mariana Kotik, Chief Strategy Officer at LNET, said the project’s value lies in “bringing together institutions, financial actors and technology partners to test different approaches in a collaborative and technology-neutral environment.” For instance, Cosmos will provide one of the participating network environments used to test cross-network interoperability and cross-border settlement scenarios.
The context: Latin America’s digital asset push
The partnership comes as Latin American financial institutions accelerate digital asset adoption. Fireblocks’ 2026 survey found that 41 percent of Latin American financial institutions had already committed budget for digital asset infrastructure before 2026 began, with 50 percent investing $1 million or more over the next 12 months; more than three times the 15 percent reported in the United States.
The region’s blockchain-in-financial-services market was $680 million in 2025 and is projected to grow at a 28 percent compound annual growth rate (CAGR) through 2034. Peersyst, which built the XRPL Ethereum Virtual Machine (EVM) sidechain on the Cosmos stack, will serve as the official provider of Cosmos-based solutions for the region.
Why Cosmos and IBC are crucial for CBDC interoperability
Cosmos joining CBWeb3 is a pretty big deal for the whole Web3 world. IBC is basically one of the only production-ready interoperability protocols that can connect sovereign blockchains without sacrificing their independence. For central banks, this is ideal; they can build their own digital currency networks exactly as they want while still being able to handle cross-border payments easily.
The Cosmos tech stack is already running over 150 blockchains for finance and payments, so it’s the go-to neutral ground for this kind of teamwork. And, watching big institutions bring Cosmos into a regulated space is a huge signal that it’s ready for the big leagues, which could really kickstart wider enterprise adoption.
For Cosmos hodlers, CBWeb3 is a great example of real-world use in a part of the world that’s moving fast on digital assets. By working with central banks and international organizations, Cosmos is making sure it’s a key part of how regional digital finance is built.
The outcome of this initiative could serve as a blueprint for other regions looking to build interoperable digital financial infrastructure.
