Most people think oracles are simple, but this is where mistakes are most likely:
Smart contracts cannot directly access off-chain data, such as token prices or match results. Oracles write that data to the blockchain.
If an oracle is manipulated, protocols that rely on its prices may liquidate positions incorrectly, so it’s crucial to use diverse data sources and decentralized nodes.
During sharp price swings, oracle prices may briefly fall out of sync with exchange order books, so leave a sufficient safety margin on lending positions.
