According to @paoloardoino, Tether Gold is introducing Scudo as a 1/1000 XAUT (gold ounce) unit to improve XAUT transfers, payments, and pricing, and all upcoming Tether WDK-based wallets will integrate the Scudo denomination, with a comparison to Bitcoin sats as context. According to @tethergold, 1 Scudo equals 1/1000 of an XAUT and is designed to make Tether Gold easier to use, track, and transact, providing a practical way to send and receive smaller amounts. For traders, these updates enable finer pricing granularity and smaller transfer sizing for XAUT on-chain activity as stated by @paoloardoino and @tethergold.
