Example

const uniRouter = new UniswapV2Router(
	'0x7a250d5630b4cf539739df2c5dacb4c659f2488d',
	'https://mainnet.infura.io/v3/'
);

Read Methods:

• Provider required for read methods.

uniRouter.read.WETH().then(address => {
	//0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2
});

uniRouter.read.factory().then(address => {
	//0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f
});

Write Methods:

• Write methods generate data for send transaction.
