What network is TUSD on?

Could you please elaborate on the network that TUSD, or TrueUSD, is operating on? As a cryptocurrency professional, I understand that understanding the underlying infrastructure is crucial for investors and enthusiasts alike. TrueUSD, being a stablecoin, aims to provide a pegged value to the US dollar. However, the question remains: on which blockchain or network does this pegged stability originate and function?
