Is there a standard for using Uniswap through smart contracts?

Smart Contracts
1

I want to swap the tokens inside a smart contract through uniswap contract for another token(Let's say i want to swap SHIB for USDC). How do i do this? Are there any standards/built contracts for doing so?

Yes it is possible, I dont know if there is an standard on that but you can check out the uniswap router: https://docs.uniswap.org/protocol/reference/periphery/SwapRouter.

I was able to do a swap like this:

function swap(address _token, bytes memory path, uint amount) public returns(uint256 result){

        IERC20 erc20 =  IERC20(_token);
        erc20.approve(address(router), amount);
        

        ISwapRouter.ExactInputParams memory params = ISwapRouter.ExactInputParams(
            path, address(this), block.timestamp,  amount, 0
        );
        if(address(this).balance == 0){
            amount = 0;
        }

        result = router.exactInput{ value:amount }(params);
    }
