Decentralized exchange Aster has announced that USD1 will be the exclusive settlement asset for all TradFi perpetual contracts on its platform, replacing USDT. The first real-world asset (RWA) trading markets to launch in USD1 include $CLUSD1, $XAUUSD1, $XAGUSD1, and $BZUSD1. Initial trading fees for USD1 pairs are set at 1 basis point for takers and -0.5 basis points for makers. Aster is also collaborating with World Liberty Financial (WLFI) to explore deep token-level integration. This partnership aims to enhance the ecosystem and promote large-scale on-chain adoption of RWA markets.
