Connect a wallet
Before you can use WOOFi, you'll need to connect your wallet. Multiple wallets are supported but a popular choice is MetaMask which can be downloaded for free as a Google Chrome extension. Other solid wallet choices include:
Choose a network
WOOFi supports multiple blockchains and you can switch between these in the upper right corner of the screen. Click the network you want to use from the drop-down list, confirm the change in your wallet, and you'll be good to go.
When swapping a token with WOOFi for the first time, you'll need to give WOOFi permission to access and move the token from your wallet. This is standard practice in DeFi, and you'll need to sign a token approval prompt which costs a small fee.
Metamask specifically will ask you to enter the number of tokens you're happy for WOOFi to have access to. Once you've entered this, you can then go ahead and execute your swap.
