Is it legal to sell USDT in Singapore?

Could you please clarify for me, is it lawful to engage in the sale of USDT within the jurisdiction of Singapore? I'm seeking clarity on whether this particular transaction falls within the legal framework of the country's financial regulations. Could you provide some insight into whether there are any specific restrictions or permissions required for such transactions to take place? Additionally, it would be helpful to know if there are any regulatory bodies or authorities that govern the sale of cryptocurrencies in Singapore, and whether USDT specifically is recognized and allowed for trading in the country. Thank you for your assistance in clarifying this matter.
