FAQs
Lightning Pool is a non-custodial, peer-to-peer marketplace for Lightning node operators to buy and sell inbound channel liquidity.
A channel is opened to you after paying an upfront premium for inbound channel liquidity of a specific size for a set duration of time (2016 blocks). Once the upfront premium is paid a channel is opened to the buyer.
Set your buy price to according to the time you are willing to wait for a match and of course your own internal cost and benefit analysis.
If there is a market match, you will pay the lower of the two prices between the bid and the ask.
You pay based on a percentage across time and it is not quite straightforward to describe the cost, so allow the software to calculate the cost for you and you will be able to confirm it.
If you want to pay a specific amount, use trial and error of creating bids until the confirmation shows you your desired fee payment size.
It will not show you an exact total, but you can see how much you will pay in fee to the seller in the confirmation, in the confirmation the seller is called the “maker”
You can check the status of your order at any time by running the following command:
pool orders list
A channel will be opened as soon as the batch transaction has received a sufficient number of confirmations. Batches are processed whenever the market clears or approximately every 10 minutes or whichever is longer.
The seller has to be online when the batch clears or the match won't be included
Not at this time but this is something we plan to add in the future.
The channel is opened automatically by the seller once the market clears.
It will stay open for a minimum of 2016 blocks (approximately 2 weeks).
No, it will remain open but the seller has no obligation to keep the channel open beyond the maturity date.
You can specify a minimum allowable channel size which will ensure that you receive one or more inbound channels greater than or equal to the size you specified.
No. The channel behaves like a regular channel.
If the lender force closes they will be banned from the market. This will not be possible in the future.
If you cannot or do not want to move the funds out of the channel off-chain, you can close the channel before the term limit with no penalties.
Opening an account requires first funding your
lnd wallet and subsequently funding a time-locked 2-of-2 multi-sig account. This account is then debited whenever an order of is fully or partially matched.When creating an account you must specify a time-lock so that you can gain access to your funds in the event that Pool is offline for a period of time. The account will expire once the specified amount of time has elapsed.
This is necessary so that users can recover funds in the event our servers were to go offline for a period of time.
You will need to close your account and then re-open your account. In the future we will enable account renewals.
You are not able to choose who to buy from but by default only well-connected nodes who are on the Bos Score List are eligible to sell liquidity.
A seller cannot avoid selling to a specific peer. All peers on the network are valid buyers.
Yes. They will be responsible for connecting to your node.
In the future this node may be removed from the market.
Buyers and sellers of channels should expect service charges of 5-25 basis points each.
A one time payment of 1000 satoshi is also required to obtain an LSAT token to communicate with the auction server. That token currently does not expire and can therefore be used indefinitely.
When the channel is opened, the cost of opening the channel is split between the buyer and seller. When closing the channel, the rules are the same as with any other LN channel: The initiator (in the Pool case the seller) pays the closing fee.
This will be different with anchor output channels however, once they are rolled out by default (they're still experimental and need to be opt in). With those, the party initiating the force close will pay the chain fee for doing so.
The seller earns the routing fees. You can also earn fees if that new channel is used by a routing node.
Yes they can adjust their routing policy however this will be penalized in the future.
Not at this time but this is something we plan to add in the future.

- Max batch fee rate is what you want to pay as part of the channel creation (you will pay for half of the open fees as the buyer)

To participate in an auction, the
poold trader daemon needs to be in constant communication with the auction server to validate and then sign potential batch transactions.Once all orders are in a final state (either fully matched or canceled), the trader daemon can be safely shut down.
As long as there are no differences in the operating system or the processor architecture, moving
poold to another machine is as easy as moving the .pool directory.However, because
poold doesn't have any private keys on its own, it always has to be connected to the same lnd node. Moving poold between nodes is not supported and will result in errors. If you need to use a different lnd node, cancel all orders and close all accounts first, then start a fresh poold with a new lnd instance.Last modified 2yr ago
