Hello everyone, I have decided to make this small introductory tutorial on how to use the LNP2P telegram bot, if you are looking for a way to buy or sell your sats for fiat shitcoin this may be the way to do it. A little context the bot was created by Francisco Calderón @negrunch in X, as you can read on his website and I quote lnp2pbot is a bitcoin exchange system for local currency, which allows person-to-person transactions to be made easily and safely using the Lightning network. It is a Telegram bot that can be used pseudonymously, without user registration or identity verification. It is a tool that only guards the satoshis (minimum unit of bitcoin) for the minimum time necessary, which provides greater security to its users compared to exchange services that have internal wallets and full custody of the funds. Lnp2pBot is an open source application so it can be freely audited, replicated, modified and redistributed.

When you take an offer, @lnp2pBot will guide you step by step through the buying/selling process.

The first thing will be to execute the command /sell in the bot. This will start a wizard that will guide us through the process. It is very simple so you will not have any problems.

Then we are asked to enter the currency, it can be EUR, USD, etc. In this example we will use USD

We enter the amount of USD to sell. We enter 1 USD as an example

In the next step the bot will ask us to define a fixed amount of sats to sell for 1 USD or select the market price option. For this example we will use market price.

The next step will be to configure the premium or discount on the sale, that is, you would sell at a lower or higher price. We also have the option of choosing without a premium or discount and that is what we will do for the example.

Finally, information about the payment methods that will be allowed is entered, and with this the order is published in the offers channel.

That's all, the order can be cancelled using the command /cancel <order id>

The buyer sees the order in the channel and takes it, from here everything happens in the bot

We accept the order in the bot and send a Lightning invoice for the amount the bot is asking for.

Once the invoice is sent by the buyer, the bot notifies the seller that payment must be made. But this is where the magic happens, well it's not magic, it's technology. The bot sends an invoice to the seller that includes a 0.6% tax for the use of the bot. This payment is made using a hold invoice. More information here

The seller pays the bot's invoice using a hold invoice

Once the invoice is paid, the bot contacts both parties so that they can agree on the payment method. Only at this moment does the bot show both parties the user ID on Telegram.

After the payment is made, the buyer must execute the command /fiatsend

Once payment is verified, the seller executes the /releases command and selects the order

The funds are released and the hold invoice is released, everything happens like a normal lightning payment. Finally, the bot shows both parties a survey to evaluate the counterpart.

The purchasing process happens in the same way, so I won't cover it because the post is already long. Next time I'd like to see the topic of communities and disputes, which can be discussed here in the comments if you're interested. I hope you're not bored, this is my first time using markdown.
