Vodafone Digital Asset Broker (DAB) and Sumitomo have reached a significant milestone by integrating with Chainlink, becoming a node operator. This achievement follows a successful proof-of-concept aimed at enhancing the exchange of trade documents across platforms. Their collaboration is driven by the desire to streamline document transfer and the processing of financial transactions within the vast $32-trillion global trade ecosystem.
The proof-of-concept hinged on Chainlink’s Cross-Chain Interoperability Protocol (CCIP), which provided a secure and interoperable framework for Internet of Things (IoT) devices at the network’s edge. This experiment demonstrated the potential of leveraging Vodafone’s IoT devices and blockchain technology to provide data for smart contracts and AI applications. Notably, it opens the door to creating a unified interface for the seamless transfer of data and tokens, with practical applications like autonomous reporting of cargo fires on vessels, which could trigger marine cargo insurance processes.
Trade documents have long been a challenge due to their presence in both paper and digital formats, often lacking interoperability and necessitating multiple transfers.
Vodafone introduced DAB in February 2022, initially trialing it with Mastercard in the United Kingdom to facilitate electric vehicle drivers in locating and paying for optimal charging solutions.
The collaboration between Vodafone and Sumitomo, initiated in May, led to the formation of a new entity, with Vodafone holding an 80% stake. Vodafone transitioned DAB, along with intellectual property, contracts, technology, and software, into this new venture. Furthermore, the two companies jointly invested in Safaricom Ethiopia.
In August, Vodafone DAB joined forces with enterprise blockchain Aventus, with a focus on improving aviation supply chains.
Chainlink’s CCIP, which launched on Ethereum’s Arbitrum One layer 2 in September to enhance scalability, was also utilized in a collaborative effort with the Australia and New Zealand Banking Group to test an Australian dollar stablecoin during the same month. These developments signify a significant stride towards efficient and secure document exchange in the realm of international trade.
