The selection of oracles for on-chain liquidity remains a complex issue due to the lack of reliable price references. Various markets are employing different oracle configurations to address this challenge. For instance, the cbETH/XSGD market utilizes the MetaOracleDeviationTimelock, while the wstETH/XSGD market employs the MorphoChainOracleV2, configured with base feeds such as wstETH/ETH and ETH/USD, alongside a quote feed of SGD/USD. Similarly, the cbBTC/XSGD market also uses the MetaOracleDeviationTimelock, whereas the WETH/XSGD market relies on another MorphoChainlinkOracleV2 with ETH/USD as the base feed and SGD/USD as the quote feed. The choice of MetaOracleDeviationTimelock over Chainlink in certain markets raises questions about the criteria for oracle selection.
