I don't use Windows.

Even better! In that case you should be able to install tor by using `apt install tor` (on most distros), and set the socks5 proxy of your preferred browser to

Code:

127.0.0.1:9050

For Firefox simply search proxy in settings -- manual configuration -- SOCKS host ... Perhaps this is a bit uncomfortable in comparison with the tor browser... Apologies, but there is not much we can do for now.

I've seen many algorithms that suggest much higher fees than necessary. In the past day (or week), a few sat/byte was always enough to confirm within 6 blocks.

We use Bitcoin Core's `estimatesmartfee` though we have done fairly limited testing on mainnet to see how accurate these guesstimates actually are. Hard to simulate in a testnet environment. Definitely something we look to optimize further if it turns out to be necessary.

I just got the problem to request payment/invoice from https://htlc.me/, (due to temporary network connectivity issues). but it's ok for an on-chain deposit, which I have received in minutes.

Please further detail what is not working for you, for example:

are you:
1. - unable to send a lightning payment from moneypot to an invoice at HTLC.me?
or
2. - unable to send a lightning payment from HTLC.me to an invoice generated from moneypot?

Just tested both ways and it seems to work fine....?

So where I can find node address (pubkey)?, because I try another faucet that needs pubkey (I tried pubkey in the config, that isn't worked), https://faucet.lightning.community/.

While we do offer the pubkey of the lightning node (go to wallet -- FAQ / GENERAL), it is not clear what you're trying to do. Opening a channel with us won't give you any balance inside your wallet.

Can we set an expired payment? look like 24 hours set by default. I want to set it in 2 hours expired time.

We could probably let you pass expiry time as a variable when requesting an invoice which would allow users to set the expiry time themselves, but what exactly would the use of this be? Seems to only add unnecessary complexity?
