The use of Uniswap as an oracle can be risky, as it is a decentralized exchange that uses automated market makers to determine prices. This means that the prices of assets can fluctuate quickly, making it difficult to accurately predict the value of an asset. As such, it is understandable why one would not want to lend when Uniswap is used as an oracle. For those who are willing to take the risk, it is important to be aware of the potential volatility of Uniswap and to only lend when the risk is acceptable. It is also important to be aware of the fees associated with Uniswap, as they can add up quickly if not monitored closely.
