Which Bitcoind wallets are used?

[indeed-a-genius]

I'm running a pruned Bitcoin core with multiple wallets.
I'd like to run LND backed by the same bitcoind node by providing LND RPC access to it. Will LND create separate a bitcoind wallet on first launch? And not touch any of my current wallets, including the default one? If so, what will be the name of the new wallet(s)?

lnd has its own on-chain wallet (using the btcwallet Golang library), so there is no wallet interaction with bitcoind. In fact, you can even use a bitcoind node that doesn't have wallet support compiled in.

The only thing I would take a look at is the prune value of your node. From experience, pruning too aggressively (e.g. less than 100 GB) can lead to sync issues, especially if your bitcoind node isn't well connected to other nodes (e.g. Tor only).
