Gold-Backed Token ZPG Makes Strategic Leap to Optimism, Signaling Major RWA Expansion

Mitsui Digital Commodities has migrated its gold‑backed real‑world asset token, Zipangcoin (ZPG), from the private Miyabi blockchain to the public Layer‑2 Optimism network. Launched under Japan’s FSA regulatory framework in 2022 and backed 1:1 by physical gold in audited vaults, the move to Optimism aims to lower transaction costs, speed settlement and enable integration with DeFi (lending, trading, collateral). Market impact: the migration increases accessibility and potential liquidity for tokenized gold, validates Layer‑2 networks for institutional RWA issuance, and may catalyze further commodity tokenization by TradFi firms — pressuring other L2s and shaping regulatory attention on tokenized physical assets.
