How to get Inbound Liquidity on the Lightning Network
There are several ways you can find inbound liquidity on LN.
1. Wait
If your node is up 24x7 and you have some outgoing channels, the network will connect to you if you simply wait.
However, it might take a couple of weeks to get a significant amount of incoming liquidity, and ideally you want your outgoing liquidity to match too.
So open a few large channels, and simply wait a few weeks.
2. Purchase things or simulate purchasing things with on-chain payouts.
If you open a channel, and spend 50% of the channel capacity on something, perhaps even sending back to your own wallet via a service like
then you could have at least one channel with inbound liquidity, plus the funds to open another channel elsewhere.
Step 1: open a channel to provider
Step 2: create a new deposit address to send bitcoin back to
Step 3: perform LN to onchain swap at provider for 50-80% of the channel capacity which you just opened
Step 4: wait 10-15 mins for your funds to arrive
Step 5: open a new channel to a different provider with the returned funds
This process could be repeated with several parties, including actual purchases of goods and services, and result in several channels with inbound liquidity as long as the channels remain active.

- Acquiring inbound channel liquidity from arbitrary nodes on the Lightning network
- Depositing funds to a Bitcoin on-chain address without closing active channels
- Paying to on-chain fallback addresses in the case of insufficient route liquidity

4. Open channels with parties who will reciprocate
The following parties will open channels back to you if you open channels to them:
5. Participate in a group loop (aka cyclic superhub, aka supernode, aka liquidity swap triangles, squares and pentagons, aka ring of fire)
Back in late 2017/early 2018 I had this idea about 3 way channel openings to share the transaction costs equally between parties, while achieving a channel opening for all. There wasn't any support for it in South Africa.

Please consider opening a channel with me, I only have 240k sats available
atm to open to 2 other parties.
I'd like at least one supernode setup.
Me -> you -> someone -> me.
And then we each have one outgoing, one incoming channel elsewhere.
Lets get the Africa supernode fabric going :)

I believe I was influenced by these writings on cyclic superhubs which explore the idea in detail: https://zmnscpxj.github.io/offchain/cyclicsuperhubs.html
Since then the concept of liquidity groups has independently exploded in the form of

Please leave a comment with a link to service if you'd like to be included.
Updates are done on a best effort basis.
On a fresh node with 5 outgoing channels, no purchased / incoming-on-request channels, it took 15 days for the first automatic lnbig connection with an additional 2 channels from other lnbig nodes within two days. So simply waiting will eventually provide some connectivity. (mid-April to start-May 2019)
