<p>As of now this is possible with <a href="https://github.com/lightninglabs/loop" rel="nofollow noreferrer">Lightning Labs' Loop</a>.  It's a non-custodial reverse submarine swap implementation.</p>

<ul>
<li>You need to build LND with some special flags to enable the feature.</li>
<li>Loop is installed and runs separately as a daemon.</li>
</ul>

<p>Once you have both running, you can simply "loop out" to send balance in your channel and receive Bitcoin onchain. </p>

@emi only for a channel between Eclair mobile wallet and an LND node that's running loopd. Then you can provide loop the channel id.

<p>i have Testnet LN Node,
i have created a wallet,
i have send on-chain funds to that wallet
i have connected to several peers
i have created several channels, all of these are outgoing one side funded channels,</p>

<p>i want to do a reverse submarine swap, i mean Pay in LN and receive in BTC</p>

<p>LN --> BTC </p>

<p>this site offers the other way <a href="https://submarineswaps.org/" rel="nofollow noreferrer">https://submarineswaps.org/</a></p>

<p>the purpose of these is to reverse a channel, or the half capacity of channel to be ready to receive LN payments. </p>

<p>of course i could just spend money, but the idea is to reverse the channel without loosing money (loosing is simulated as its in testnet)</p>

<p>thanks</p>

As of now this is possible with [Lightning Labs' Loop](https://github.com/lightninglabs/loop). It's a non-custodial reverse submarine swap implementation.

* You need to build LND with some special flags to enable the feature.
* Loop is installed and runs separately as a daemon.

Once you have both running, you can simply "loop out" to send balance in your channel and receive Bitcoin onchain.
