Ethereum

I am writing a smart contract which is buying coins on uniswap, is there a way to use other routers ? I would like to get best prices and lowest fees. Any links would be great too.

A common way is to use an external API that returns the swap route as calldata that you can sign and call like 0x Swap API

Years ago the earliest version of routers were onchain like 1inch Protocol but nowadays it is the standard to do this off chain due to gas costs, the proprietary nature of these routing algorithms and the emergence of onchain market makers / solvers. Technically you could build it yourself, a lot of effort though.
