I need Weth for my dapp. So I looked at how AirSwap converts ETH to Weth. On the Rinkeby testnet, AirSwap calls this contract and uses the "deposit" function. I see from the code how this would work. Also I can see that this contract is owned by 0x.
My question is: Can I just call that exact contract for my Dapp too? Is this the recommended way to exchange Weth for Eth?
