According to CoinMeta, Switchboard announced that it has suspended its oracle services on multiple networks due to the detection of potential security issues, including SUI and Aptos. This preventive suspension also affected Iota and Movement. It is important to note that the suspension only applies to the oracle services of Switchboard and not to the chains themselves. The reliability of oracles is crucial for DeFi applications; if the oracle services are suspended, related protocols may need to adjust their markets or rely on backup systems. Users and developers will be watching for detailed explanations of the incident, including which services are affected and whether any data has been manipulated.
