SBI Holdings has announced plans to launch a yen-pegged stablecoin, JPYSC, in the second quarter of 2026. The stablecoin will be issued by Shinsei Trust and aims to reclaim market share from dollar-denominated stablecoins. The launch is contingent on regulatory approval under Japan's Payment Services Act. Given SBI's ties with Ripple, there is speculation that JPYSC may be launched on the XRP Ledger. In other developments, Charles Edwards has suggested that Ethereum's focus on quantum-resistant security could lead to it surpassing Bitcoin in market capitalization within five years. Ethereum's roadmap for 2026 prioritizes quantum security, a concern that Bitcoin developers have not emphasized. Meanwhile, Cardano is set to receive its first major stablecoin, USDC, within the next two days. The launch is expected to enhance Cardano's interoperability and attract more applications to the blockchain, which has a market capitalization of $10.2 billion, with over half locked in staking.
