According to official sources, the Pragma oracle service has been launched on the Starknet mainnet. As part of Starknet's future plans, the network intends to add STRK as a new fee token outside of ETH, and this mechanism requires an oracle to provide real-time STRK <> ETH price feeds. In the short term, Starknet plans to use the semi-decentralized Pragma oracle as a temporary solution, while a long-term decentralized solution will need to be achieved through future governance.
