is there any reference implementation of a smart contract that checks multiple dex's for the best price onchain, or is hardcoding uniswap's universal router the best approach? are there similar routers for other dex's? cc @dcposch.eth im guessing you guys explored this for daimo

You can use Uniswap TWAP/TWAL. Unfortunately these are averages: median would be better and more resistant to manipulation. TWAP/TWAL does have the advantage that only uses previous-block pricing = it's resistant to within-block/within-tx manimuplation
