Set up your wallet
Create a wallet and write down your recovery words. If you stop partway through, you can finish the backup when you return.
Save a backup file too. Winnow needs it to find your past payments when you restore the wallet.
Receive bitcoin
Share your address or QR code. Keep Receive open to watch for a payment, then check its confirmation in your wallet.
Send bitcoin
Enter an address and amount. Check the address, fee, and total before you send, then follow the payment’s status.
Pay someone again
Name someone you’ve paid, or save their payment card. Next time, choose them in Send.
Save with other people
Choose who shares the wallet and how many approvals a payment needs. With two approvals out of three, one person can be away and the other two can still pay.
For shared control, each person must keep their own key. If you choose just one required approval, any one of them can spend.
