Mitsui & Co. Digital Commodities announced on April 17, 2026, that it is bringing its Zipangcoin (ZPG) tokenized metals asset to the OP Mainnet, marking the product's first issuance on a public blockchain since its 2022 launch. The company also said Japanese exchange GMO Coin is set to list ZPG on April 20.
"Bringing Zipangcoin to a public blockchain like Optimism is a major step toward increasing its global accessibility and liquidity," a spokesperson for Mitsui & Co. Digital Commodities said. "The efficiency and scalability of the OP Mainnet allows us to offer the stability of a gold-linked asset with the benefits of decentralized finance."
Zipangcoin is a digital asset pegged to the price of gold and denominated in Japanese yen. Since its initial launch in 2022 on a private blockchain, the move to the Optimism network, a leading Ethereum layer-2 scaling solution, is expected to significantly lower transaction costs and increase speed for ZPG holders. The upcoming listing on GMO Coin, a major Japanese crypto exchange, will provide a direct fiat on-ramp for local investors.
This integration serves as a strong indicator of the growing Real World Asset (RWA) tokenization trend on public blockchains. By bringing an institutional-grade, gold-backed token to its ecosystem, Optimism gains a key asset that could attract more risk-averse capital. For Zipangcoin, the public launch and exchange listing could unlock significant liquidity and establish ZPG as a key player in the expanding RWA market on-chain.
