Banco Inter and Chainlink Bridge Brazil’s Digital Real to Global Trade in Landmark Blockchain Pilot
Banco Inter and Chainlink link Brazil’s Drex CBDC with Hong Kong’s Ensemble, enabling faster, lower-cost blockchain trade settlements.
Brazil’s Banco Inter has completed a groundbreaking blockchain trade finance pilot in partnership with Chainlink, the Central Bank of Brazil, and the Hong Kong Monetary Authority. The initiative successfully connected Brazil’s Drex central bank digital currency (CBDC) network with Hong Kong’s Ensemble platform, marking a milestone in the use of distributed ledger technology for cross-border commerce.
The pilot, conducted as part of Phase 2 of Brazil’s Drex project, simulated real-world export settlements between the two jurisdictions. Using Chainlink’s oracle infrastructure, the system enabled tokenized payments and smart contracts that automated title transfers and payment execution between importers and exporters. This interoperability dramatically reduced settlement times—from several days to near-instantaneous—and cut transaction costs by as much as 50%.
Banco Inter described the pilot as a step toward making international trade more efficient, transparent, and inclusive. “By supporting tokenized payments and automating title transfers via smart contracts, the platform lowers costs, reduces risk, and opens international markets opportunities to small and medium-sized businesses,” the bank stated.
Standard Chartered Bank also took part in the test, validating the technology’s real-world viability and reinforcing the role of blockchain in trade finance. Historically, trade finance has been hampered by delays, paperwork, and intermediaries. By replacing manual processes with blockchain-based automation, the pilot demonstrated how digital currencies and smart contracts can streamline global transactions while mitigating fraud and operational risks.
Chainlink’s role was pivotal. As the interoperability layer, its oracle network connected Brazil’s Drex blockchain with Hong Kong’s Ensemble system, ensuring secure, tamper-proof data exchange for each transaction. This setup represents one of the first large-scale demonstrations of CBDC interoperability between major financial centers. Experts suggest such cross-chain integrations could become standard infrastructure for global settlements, addressing one of the main inefficiencies in international payments.
Brazil’s digital currency program, Drex, is advancing rapidly under the Central Bank’s oversight. While often referred to as a CBDC, Drex functions more as a programmable infrastructure designed to modernize Brazil’s financial system, expand credit availability, and enhance financial inclusion. According to Central Bank data, stablecoins account for roughly 90% of crypto transactions in the country, positioning Brazil among the top five nations globally for crypto adoption.
The pilot also underscores the growing convergence between digital assets and regulated finance. With successful interoperability between Drex and Ensemble, the framework could serve as a model for emerging markets seeking to integrate CBDCs with private blockchain networks. As Brazil continues to refine its digital real, future phases of the Drex project are expected to focus on scalability, retail integration, and broader international cooperation.
The collaboration between Banco Inter and Chainlink shows how blockchain can move beyond experimentation into real-world infrastructure—redefining cross-border finance for a more connected, efficient global economy.
