(OPTIONAL) Converting Back to ETH 

Flexibility at your fingertips! 🤲

You can convert WETH back to ETH, but for the rest of the threads we'll need some WETH so make sure to have some.

💡Pro Tip: Always ensure you have enough ETH for gas fees when performing transactions. On your local fork, you’ll have 1,000,000,000,000 ETH for testing. 

Now that you have WETH, you're ready to transfer it and interact with other protocols! 

Next up, transferring WETH to another address. Stay tuned! ⏳

Step 3: Understanding the `deposit()` Function

The `deposit()` function wraps your ETH into WETH. It's a simple way to convert ETH to an ERC20 token, enabling you to interact with protocols that require ERC20 tokens. ♻️
