ChainThink report, according to The Defiant, Japan’s Mitsui & Co. digital commodities subsidiary MDC has announced the deployment of its tokenized gold, silver, and platinum assets, Zipangcoin (ZPG), onto OP Mainnet.

This marks the first public blockchain launch of ZPG since its 2022 debut, previously operating on the private chain Miyabi. Japan’s exchange GMO Coin will list ZPG on April 20.

MDC states that the selection of OP Mainnet was driven by research into the growth of the OP Stack ecosystem, which processed over 6 billion transactions in 2025.

Zipangcoin is a commodity-backed crypto asset compliant with Japan’s regulatory framework. In 2025, the on-chain tokenized RWA asset market size grew to approximately $18.6 billion.
