According to Paolo Ardoino, Tether introduced Scudo as an on-chain unit equal to one thousandth of an XAUT ounce of gold, defining Scudo as 0.001 troy ounce within the Tether Gold framework (source: https://twitter.com/paoloardoino/status/2008541912060547496; source: https://tether.io/news/tether-introduces-scudo-redefining-fractional-gold-ownership-onchain/). Tether stated that Scudo is meant to redefine fractional gold ownership on-chain, providing a standardized denomination for the Tether Gold ecosystem that traders can reference for settlement and pricing workflows (source: https://tether.io/news/tether-introduces-scudo-redefining-fractional-gold-ownership-onchain/). For trading calculations, the specification implies 1 XAUT equals 1000 Scudo and Scudo pricing is mechanically derived from XAUT by a 1 to 1000 ratio, enabling direct conversion of XAUT price quotes into Scudo terms (source: https://twitter.com/paoloardoino/status/2008541912060547496; source: https://tether.io/news/tether-introduces-scudo-redefining-fractional-gold-ownership-onchain/). The announcement was published on January 6, 2026 via Ardoino’s X post and Tether’s newsroom, setting the reference parameters for market integrations and quoting conventions (source: https://twitter.com/paoloardoino/status/2008541912060547496; source: https://tether.io/news/tether-introduces-scudo-redefining-fractional-gold-ownership-onchain/).
