Facebook's Libra project (2019–2022)
Facebook announced Libra, a global stablecoin, in June 2019 with backing from Visa, Mastercard and other partners. US and European regulators objected, several partners withdrew, and the project was renamed Diem and scaled back.
The Diem Association sold its technology assets to Silvergate Bank in early 2022 and wound down.
It showed that a technology company can build the software for global payments but cannot launch without the licenses and bank relationships incumbents already hold.
Polygon is taking the opposite route, buying an existing licensed business instead of asking regulators to create a new category for it.
