Ripple's CTO, David Schwartz, remains optimistic about launching the company's U.S. dollar-pegged stablecoin, $RLUSD, by the end of the year, despite challenges. Announced in April, the stablecoin will be available on $XRP Ledger and Ethereum. Testing began in August, and exchange partners like Uphold and Bitstamp were named in October. Schwartz highlighted the holiday season as a potential delay factor and emphasized the importance of a coordinated launch with partners. The stablecoin is regulated by the New York State Department of Financial Services, adding complexity to the process.
