Before receiving coins over the Lightning Network, you need to ensure that your channel has incoming capacity. See the explanation below.
In order to receive Lightning payments, some conditions must be met:
1. Nothing can be received immediately after creating a new payment channel, as ‘room’ for incoming funds has to be made by spending some funds first. A payment channel can be thought of as a full bottle of water: in order to pour something in one first has to pour something out.
2. Each channel implicitly contains a reserve which is unspendable and typically takes about 2% of the channel’s capacity. You must spend an amount matching that reserve to make receiving possible. Unspendable channel reserve is the reason you see a negative receive limit when a new channel is full. It indicates how much you need to spend before anything can be received through the channel.
3. Every payment request is disposable, they can’t be fulfilled twice. So you will need to issue a new individual payment request for every incoming payment you wish to receive.
4. Wallet needs to be online in order to receive off-chain funds.
You can also gain incoming capacity by having someone open a channel to you. Check out "Receiving a payment" in my
Electrum Lightning Network walkthrough for some useful tips.
