uniV2Router02

lucycodes42

The code snippet above contains the implementation of the UniswapV2Router02 contract. This contract is deployed at 0x7a250d5630B4cF539739dF2C5dAcb4c659F2488D on the Ethereum mainnet, and the Ropsten, Rinkeby, Görli, and Kovan testnets.

In addition to the IUniswapV2Router02 interface, the UniswapV2Router02 contract also has two external functions. The first function, removeLiquidityETHSupportingFeeOnTransferTokens, is used to remove the liquidity fee associated with the transfer of tokens. The second function, removeLiquidityETHWithPermitSupportingFeeOnTransferTokens, is used to remove the liquidity fee associated with the transfer of ETH with a permit.
