It's a new one from June 2023, backed 1:1 by USD or liquid assets, from what I read, and it's issued by a Hong Kong firm, instead of a US-based one. Exactly what Binance said they would do. Except it's still US-pegged, they initially said they might peg it to another currency in the world but looks like they gave up on that rather silly idea. So, most likely, it's Binance's stablecoin, just like BUSD was. The difference is it doesn't have any history and it isn't issued from a US-based jurisdiction.
