[LNBig](https://lnbig.com/) offers channel opening services for a very reasonable fee. They provide an LNURL link to open the channel. Which app if any within Umbrel supports this standard? ---

ThunderHub has a LNURL button on the Home page, I believe you should be able to use that. However, you should keep in mind that LNBig only opens a channel temporarily, they will close it after 1 month unless there is continuous activity. Another option that I have used for inbound liquidity is [BitFinex](https://ln.bitfinex.com/). You can open a channel to the exchange and send satoshis to your trading account. You can then do a straight swap from Lighting BTC to BTC and withdraw that to your wallet. This way you get a lightning channel with a remote balance and the only cost is opening the channel and then the withdrawal fee from BitFinex (0.0004 BTC). Also note that BitFinex have a minimum 4,000,000 satoshi for opening a channel directly with them, but if you need a smaller amount you can [find a connecting channel](https://1ml.com/node/03cde60a6323f7122d5178255766e38114b4722ede08f7c9e0c5df9b912cc201d6) which allows smaller amounts. ---

ThunderHub’s LNURL seems to only work for payments, not channel openings yet. Seems like it’s still in the works. It’s a fairly new standard. The Bitfinex idea is great! 🙂 ---

If you do want to continue with LNBig. Connecting your node to Zap app works for channel LNURL’s. ---

if you’re going to open a channel with Bitfinex and already have outgoing liquidity, better to wait. Demands to deposit toward Bitfinex is high, so at least profit from it ^^ ---

Haha … true … although has anyone really made any serious money with lightning channels? OK, my recipe for maximum success: 1. Open a channel to BitFinex 2. Send half to the exchange via lightning 3. Swap lightning BTC -\> BTC 4. Transfer BTC to BlockFi for 5% interest 5. Profit 😅
