According to CoinMeta, Rosen Convenience Store has collaborated with netstars to conduct real-world experiments on stablecoin offline payments, covering USDC, USDT (including Solana, Morph, Polygon chains), and JPYC (including Polygon). The average processing time for this payment process is about 5 seconds. No new buttons were added, and the transaction fees and exchange rate costs vary depending on the wallet used. In the future, efforts will continue to advance multi-wallet integration and commercialization exploration.
