• Messages: https://raiden-network-specification.readthedocs.io/en/latest/messaging.html#withdraw-request-message

Remarks

• The user needs ETH on the Raiden Account to withdraw and the modal for withdraw needs to include that (see modal on the Withdrawal Screen)

Removed from the product backlog as it is a rare use case, if the user just sends tokens and adds a lot of complexity

@christianbrb yes this will make more sense after we implement receiving

Design: Looks like deposit

@taleldayekh Thanks, looks like a bigger change.

1. Where is the settle button?
2. Where do we put the message "Please wait until your channel is settleable. this may take some time."

[taleldayekh]

User clicks close channel icon and confirms in dialog. Deposit/withdrawal icons are disabled and small spinner is displayed while the closing is in progress. Once the channel has been closed an icon for settling appears from which the user can settle the channel. Not sure how the settle icon should look.

[taleldayekh]

An alternative would be to move the buttons instead of using icons for the close and settle. The flow would look something like this:

This also makes it very clear for the user that it is a close action. The icon might be a bit ambiguous.
