Super DCA Swap

forked from https://github.com/0ximmeas/univ4-swap-walkthrough

This is a simple contract that allows you to swap between two tokens using the Uniswap V4 protocol.

The contract supports swapExactInputSingle using a PoolKey and swapExactInput using a PathKey array.

Usage

This contract is designed to be intergrated with inside of the Super DCA Pool contracts. It can be integrated in Solidity as follows:

1. One time token approval for the contract to spend the token.

swapContract.approveTokenWithPermit2(tokenAddress, amount, expiration);

2. Transfer the token to the contract and call the swap function (must be one transaction)

inputToken.transfer(address(swapContract), amountIn);
swapContract.swapExactInputSingle(poolKey, zeroForOne, amountIn, minAmountOut, receiver);

Important: The transfer and swap must be in the same call (e.g., inside a multi-call transaction).
