How to get Inbound Liquidity on the Lightning Network

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.

3. Purchase inbound liquidity

The following services will allow you to purchase incoming liquidity to your node:

Loop in/out of LN and onchain

Lightning Loop is a non-custodial service offered by Lightning Labs to bridge on-chain and off-chain Bitcoin using submarine swaps.

The service can be used in various situations:

  • 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

Author's note: when time allows a more detailed overview with examples may be provided

Pool

Pool is a non-custodial, peer-to-peer marketplace for Lightning node operators to buy and sell channels.

3rd party examples

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 :)

Earn.com $1 tasks from ICO spam funded this.

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

Hello!

hey team. Unfortunately my node went down a few days ago and I have two channels open with LNBig-13 and I have outdated SCB, I’m reaching out to my peers for initiating a force closure.
Could you please force close on me?

Here’s my pubkey: 02827ff9e6664c1608e1cb65182c73c68395cb079492a8a4482045c4561c5aa179
You should see 2 channels for this. Please help?

sorry about this, I don't think anyone will see your message except for me getting a github notice, or someone reading the comments long after.

I don't have any channels open with your node.

perhaps send a message to https://twitter.com/lnbig_com and find contact details for other nodes?

Bretton,

We discovered some great service providers from your list, particularly lightningnetwork.plus. Thank you for this!

I wanted to pass on that I just launched Coincept.com, an inbound channel liquidity service on our website for our node The Captain (https://1ml.com/node/0202e7727ee46d943a44c7bf0dce14220a839630dee67d03446bf935178b55a0df). We have a web interface where you can select your channel capacity, input your node pubkey, and pay your invoice via on-chain or lightning.

Min channel size is 100k sats and max is 25M. We plan to increase the maximum channel size in the future. The fee is 20bps (0.2%) + channel opening/closing fees. Channels will be kept open for at least 1 month and longer if there is any activity.

If anyone has any questions feel free to reach out.
