Sumitomo Trade Document Network Partnership Adds Chainlink Involvement
A successful proof-of-concept (PoC) venture between Vodafone and Japanese trading and investment giant Sumitomo has resulted in Vodafone’s Digital Asset Broker (DAB) platform now being integrated into the Chainlink network as a node operator.
Vodafone provided details on the Chainlink Labs tie-up via a blog post published to its website on Tuesday. The primary objective of this partnership is to enhance the seamless transfer and processing of financial documents within the $32 trillion global trade ecosystem.

Leveraging Chainlink’s cross-chain interoperability
The proof of concept leveraged Chainlink’s Cross-Chain Interoperability Protocol (CCIP), offering a solution that bridges the gaps in document management and financial transaction processing. DAB’s core function is to provide enhanced security and interoperability among Internet of Things (IoT) devices on the edge of a network.
The results of this initiative have demonstrated the potential for Vodafone’s IoT devices and blockchain technology to furnish data for use in contracts and artificial intelligence (AI) applications. Furthermore, the prospect of creating a unified interface for data and token transfers is now within reach.
For instance, envision a scenario where a cargo vessel detects a fire outbreak. Thanks to the collaborative efforts of DAB’s platform and CCIP, this crucial information could be autonomously relayed to smart contracts, potentially triggering an efficient marine cargo insurance process.
Convoluted legacy process
Trade documents have long posed a significant challenge due to their existence in both physical and digital formats, often lacking interoperability. This predicament necessitates repeated handovers and makes the exchange of such documents a convoluted process.
Vodafone introduced the Digital Asset Broker in February 2022. Their initial application of DAB in the United Kingdom involved a partnership with Mastercard, where they trialed an app designed to assist electric vehicle drivers in locating and paying for the most suitable charging options.
In a subsequent move, Vodafone and Sumitomo joined forces in May, culminating in the creation of a new entity in which Vodafone maintained an 80% stake. In addition to transferring DAB, Vodafone also contributed intellectual property, contracts, technology, and software to the new venture. This partnership extended further with joint investments in Safaricom Ethiopia.
In August, Vodafone DAB solidified its presence in the enterprise blockchain arena by collaborating with Aventus. Their shared mission is to enhance the efficiency of supply chains within the aviation industry.
Chainlink’s CCIP made a significant leap in September when it launched on Ethereum’s Arbitrum One layer 2, promising to enhance scalability. In the same month, it collaborated with the Australia and New Zealand Banking Group to test an Australian dollar stablecoin, underscoring Chainlink’s commitment to transformative developments within the blockchain space.
Early blockchain interest
Sumitomo had expressed a desire to utilize blockchain technology going back a number of years. In 2018, the corporation’s US entity joined the Blockchain in Transport Alliance (BiTA) with a view towards using blockchain technology within its logistics business.
Earlier this year, the conglomerate invested in Japanese logistics blockchain project TradeWaltz. In June, its US subsidiary was involved in the first-ever transaction of tokenized carbon credits.
As Vodafone and Sumitomo continue to push the boundaries of innovation in trade document management, their partnership with Chainlink brings us one step closer to a more efficient and interconnected global trade ecosystem.
