Voltage can create a just-in-time channel to your node. Paste a Bolt 11 invoice and we'll
respond with a wrapped version of that invoice. When this new invoice is paid, a channel
will be automatically created to your node and the payment will be forwarded to that
channel. This is all noncustodial: we can’t intercept the payment.
When our service receives your invoice, we create a new "wrapped" invoice with the same
preimage hash. That means that we can't intercept the payment, because only your node knows
the preimage. Additionally, we add the cost of a channel open and routing fees to the
amount. Then we return this new invoice to you.
When the invoice we provide is routed to our node, we open a zero-conf channel with your
node for an amount larger than the invoice itself, then immediately forward the payment
through that channel to you.
