Sony Bank, the banking arm of the Japanese gaming and entertainment giant, has initiated a stablecoin trial on the Polygon blockchain, backed by Polygon and Settlemint. This move is part of a proof-of-concept to issue its own yen-pegged stablecoin. According to local media outlet Nikkei, Sony Bank is partnering with Settlemint for this pilot project. The trial aims to explore the potential benefits and applications of a proprietary stablecoin in the financial ecosystem.
