mempool VS lnd

That's about 50$? I don't blame them https://mempool.space/

get some theory of mind. you are a person who is willing to pay onchain fees to use your trezor or open a channel. there are people in the world who are not willing to pay these fees and they probably outnumber you. and the plan has been spelled out in plain english a million times. the fees are supposed to go up by design. this means that most people will not self-custody, whether it is legal or not, and even if they would like to.

I’m not an expert so someone smarter than me can clarify, but the high/priority rate is the going rate (estimate) to get confirmed on the next block. Medium is the average rate for those transactions to be confirmed next. You can see current and historical rates at mempool.space.

The current fee to get into next block is about 40 sats/vB.

Check mempool.space for a better idea of how big a fee you need to offer to get into the next block.

The mempool is a bit crowed now. A few weeks ago it was only around 5 - 10 cents, and now it is between 3 and 13 dollars. (yesterday even 25 dollar) If you have a lot of UTXO's it can be very expensive to consolidate them all. In that case I would wait till the mempool is less crowed for lower transaction fees. it is important to understand that whirlpool or wasabi wallet will take many UTXO's (transaction fees) to mix your coins and maybe in the future exchanges don't want to touch your mixed coins. I mixed all my KYC coins as I'm not planning to exchange my bitcoin for fiat via a exchange in the future.

Install LND: https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md#install-lnd Install Bitcoin Core: https://github.com/bitcoin/bitcoin/blob/master/doc/build-windows.md#building-with-mingw-w64-cross-tools

To be able to follow along, you must have both bitcoind and lnd installed.

If you want multiple users, you'll need multiple node instances. LNbits (mentioned by /u/sos755) does not implement this. Rather, it simply abstracts the funds associated with a single node into multiple logical accounts. This means that the node administrator still has underlying control of all funds associated with the node. See this GitHub discussion for a bit more info: https://github.com/lightningnetwork/lnd/issues/2652

LND doesn’t use BIP39 mnemonics. https://github.com/lightningnetwork/lnd/blob/master/aezeed/README.md

Both Bitcoin Core and LND have binaries available for macOS, for example. I have not seen an actual guide to set everything up on macOS tho. It's quite similar to Linux honestly.

As for taproot change addresses, this has been the default behaviour since version 0.15.5. Just update your lnd and you're all set.
