World First 0.9 BTC Settles 380 Tons of Copper: KAI Exchange and Web4 Technology Signal the End of the Bank L/C Era

In a groundbreaking development for global finance, a significant physical trade valued at approximately $4.43 million USD was successfully settled on March 10, 2026, using 0.9 Bitcoin as the primary settlement engine. This transaction, facilitated by KAI USAD Global Exchange, marks the first instance of digital assets replacing traditional Bank Letters of Credit (L/C) in large-scale industrial trade.

Redefining Global Purchasing Power with Bitcoin

The deal involved the Dubai-based Dubai Ocean Nuclear Energy Mineral Group, which utilized the 0.9 BTC to price and settle the trade of 380 tons of raw copper plates. At the time of the transaction, Bitcoin was valued at approximately $4.928 million USD per unit. The value realized from 0.9 BTC, roughly $4.43 million USD, precisely covered the cost of the copper, which was priced at $11,725 per ton on the London Metal Exchange (LME) after adjusting for premiums. This event signifies the first successful “Pricing Transaction” where Bitcoin served as the core pricing benchmark for a cross-border physical commodity.

Disruption of Traditional Trade Intermediaries

This revolutionary trade bypassed the complex and time-consuming traditional process involving Bank Letters of Credit, which typically entails multi-national audits and significant fees. Instead, the transaction leveraged a streamlined workflow:

• •
  The trade was anchored in the KBBB Exchange cluster located at One Central, Dubai Financial District.
• •
  Enterprise KYB accounts across multiple countries were used within the KAI Exchange system, with the digital currency USAD employed for trade guarantees and warrant settlement.
• •
  While sea freight takes approximately 22 days, the financial settlement was completed in seconds.

KAI Exchange: A Pioneer in Web4 Technology

As the clearing hub for this historic trade, KAI Exchange is highlighted as the world's first trading platform integrating the TOK and Banaba Web4 public chains. The KBBB ecosystem is noted as the only entity currently supporting these Web4 standards, ensuring settlement security, trade privacy, and regulatory compliance.

Thomas Zhuo, a veteran digital asset trader, commented on the significance of the event, stating, “Exchanging 0.9 BTC for 380 tons of copper is more than just a swap of numbers; it is the ultimate leap for crypto assets—moving from ‘virtual speculation’ to the very ‘bedrock of physical trade.’ KAI Exchange is no longer just a platform for matching assets; it has become the ‘digital heart’ of future global trade clearing.”

Industry Implications and the Future of Trade

Industry analysts view this transaction by the Dubai Ocean Nuclear Energy Mineral Group as a pivotal moment, suggesting that decentralized assets like Bitcoin are poised to challenge legacy systems such as SWIFT. The key advantages highlighted include significantly faster settlement speeds (seconds versus days/weeks), the use of digital currency and smart contracts for guarantees instead of L/Cs, and the underlying Web4 technology (TOK & Banaba Dual Public Chains) offering enhanced privacy and blockchain traceability.

KAI Exchange has also outlined an ambitious roadmap to clear 3 million tons of raw copper annually, representing over 10% of the global copper trade, and aims to build a digital financial ecosystem with a total clearing scale of 15 million tons, valued at $175.5 billion USD, over the next five years. This initiative signifies a major shift from traditional fiat settlement to digital credit asset settlement in global commodity pricing.
