A Monero wallet for Telegram

A Telegram Monero tip bot written in go.

Introduction

What can this bot do?

MoneroTipBot is the one and only, first open source Monero wallet for Telegram that started with a CCS Proposal and has been funded by the great Monero community.

Notice:

This is a custodial Monero wallet service by the bot operator. You do not own your private keys. The bot operator owns them! Beside the wallet itself, nothing will be stored on the server - where the bot is running - ever. No user data, personal information or otherwise personal data will be stored. The bot is expected to be stable. However, always have in mind that you might lose your money due to a bug or we can get hacked and lose all funds. Use this bot on your own risk!

Features:

  • Everything happens on-chain.
  • No transaction is stored on disk or a database.
  • Always synced wallet. Unlike other wallet clients, there is no need to wait until the wallet is fully synced.
  • Group-friendly spam-free messages
  • Sensible wallet information will always be sent to user as private message.
  • Tip users on Telegram within groups. Optionally send them a message along with the tip.
  • Send Monero to regular addresses.
  • Receive Monero on regular addresses.
  • Make Giveaways within groups.
  • Generate a QR-Code image and share it comfortably with others.
  • Make transactions by scanning or uploading a QR-Code image.
  • Deposit to account.
  • Withdraw from account.
  • Clickable TX Hash link to blockexplorer.

Invite this bot to your group (bot needs no admin rights) and enjoy Monero in Telegram.

For more information about the commands please use the help command.

Happy tipping!

Commands

/help tip

/tip username amount message

Amount takes no trailing XMR symbol! Tip a user with a certain amount. All users who started the bot will be notified upon a tip. Optionally you can specify a message to be sent along with the tip. This message will be forwarded to the user if that user has started the bot.

Notice:

Make sure the telegram user you want to tip actually exists, otherwise the moneros will be gone!!!

Unknown users to the bot, will be tipped regardless whether or not they exist in Telegram.

You cannot tip users who do not have an account at MoneroTipBot within the bot PM. Those users can only be tipped within a group.

Optionally, you can use the @ sign when giving the username. Exception to this is when you tip on a reply message. Then you don't need a username and only the amount. Amount has to be a number. Use decimals if you need fractional amounts (like 0.1).

/help send

/send address amount

Amount takes no trailing XMR symbol! Send a certain amount to a regular monero wallet address. Amount has to be a number. Use decimals if you need fractional amounts (like 0.1).

/help balance

/balance

Show your current balance. Balance is the total balance. Unlocked balance is what is free to spend and the number of spent outputs gives you a hint to how many times you can tip. If balance is locked the output will show the estimated time until unlocked.

/help giveaway

/giveaway amount

Amount takes no trailing XMR symbol! Make a giveaway within a telegram group. This is a group command. If this bot is in a group and you are a member of that group, you can make a giveaway with the amount you want to give away. The first user in that group who clicks on the 'Claim' button will receive that amount and a tip will happen between the giver and the taker. Amount has to be a number. Use decimals if you need fractional amounts (like 0.1)

/help generateqr

/generateqr amount description

Generate a QR-Code image with the desired amount and optionally a description to share with others. The other person can then paste this image into the bot PM and can do a transaction.

Every QR-Code image generated will use a new subaccount address to avoid giving away your main wallet address.

If you don't specify any parameter, it will generate a QR-Code image with just your subaccount address.

The bot will try to parse the QR-Code according to RFC 3986. If the QR-Code is RFC 3986 compliant you will be prompted with the content of the QR-Code (address, amount, recipient, description) and buttons to make the transaction or cancel it.

Example: /generateqr 10 thank you for the donation. much appreciated! :)

/help withdraw

/withdraw address

Withdraw everything from the tip bot wallet to your own wallet address.

Make sure you double-check the recipient address to make sure you are sending to the right address.

Administration/Configuration

This section is for the bot operator.

Configuration is done in the settings.yml YAML file.

Overview of the settings file:

#Telegram Bot Settings

telegram_bot_token:

Token of the Telegram bot. This is the token you get when you create a new bot in telegram via @BotFather.

rpcchannel_uri: "tcp://127.0.0.1:5555"

This is the socket for the ZMQ REQ/REP channel for the communication between the bot and external applications. It can be extended to do any kind of stuff. For now it is being used by the notifier in cmd/notifier to send a message to one user or broadcast a message to all users.

blockexplorer_url: "https://xmrchain.net/tx/"

This is the link to the XMR blockexplorer when the bot sends the output about a transaction that happened and is used in the TxHash as an HTML anchor link. We use xmrchain.net here.

BOT_NAME: ""

The name of your telegram bot (@username, not the display name) as given in the creation process via @BotFather.

DEV_DONATION_ADDRESS: "88jspkqPmvvc9L3LovdhjoCW2eBSKk4VNTsrdWqB4CYdBfKRWH5yL39bE6NP5Di2Wgix1cxBgKMAiXMbUwCBY3Dk2WvwSSA"

This wallet address of (preferrably the bot operator) will be used in the message that pops up when a user tries to tip himself/herself. Or leave it as it is with this wallet address. This is the address of the developer of this bot. He will be happy to receive tips :)

MIN_TIP_AMOUNT: 0.00042

The minimum amount that is allowed to tip. You shouldn't set this lower than the fees it requires to do the transaction.

GIVEAWAY_FILE: "giveaways.json" # absolute path will also work

This is the path to the file to save giveaways. Since giveaways can last for a long time (if nobody claimed it yet) we want to store them in files, in case the bot goes down or has to be restarted by the bot operator.

BROADCAST_NOTIFICATION_INTERVAL: 10

This is the interval broadcast messages will be sent out to users, in seconds. Leave it at 10, since Telegram has restriction on how many times a bot can message users per minute/second, etc. See https://core.telegram.org/bots/faq#how-can-i-message-all-of-my-bot-39s-subscribers-at-once for more information.

LOGFILE: "monerotipbot.log"

Telegram does not give us the information about how many groups the bot is in. We use a trick here, we track every Chat.ID of every message to track in how many groups the bot could possibly be:

// track in how many groups this bot is actually used in
if update.Message.Chat != nil {
  mutex.Lock()
  groupsBotIsIn[update.Message.Chat.ID] = update.Message.Chat
  mutex.Unlock()
}

As you can see, this is not accurate, and is just for informational purposes to get an estimated value about the group metric. The logfile will show public and private group chatIDs and the chatID of users who private message the bot within the bot PM.

#Monero Wallet RPC Settings

monero_rpc_daemon_url: "http://127.0.0.1:6061/json_rpc"

This is the URL to YOUR (the bot operator's) wallet RPC daemon. Everything happens over this RPC wallet daemon.

monero_rpc_daemon_username: ''

You should enable HTTP Digest Login on the Monero wallet RPC daemon with the --rpc-login parameter, when starting the RPC daemon.

monero_rpc_daemon_password: ''

You should enable HTTP Digest Login on the Monero wallet RPC daemon with the --rpc-login parameter, when starting the RPC daemon.

IS_STAGENET_WALLET: false

Is this bot working with a stagenet wallet? That is, has the Monero wallet RPC damon been started with the --stagenet flag? If so, set to true here or things will not work.

#Statsd Settings (Metrics Logger)

USE_STATSD: false

This bot uses a statsd client to collect some application metrics all over the place (in the code). Set to true if you are running your own instance of a statsd backend. This works perfectly with a statds-graphite-grafana backend and was tested with this docker container https://github.com/kamon-io/docker-grafana-graphite. Follow the instructions there to set up a statsd backend for your bot.

statsd_address: "127.0.0.1:8125"

The socket for the statsd backend if you use one.

statsd_prefix: "mytipbot."

The prefix for all statsd metrics.

#Bot Helper Messages

welcome_message: ""

Welcome message to display when a user PMs the bot for the first time and starts it.

help_message: ""

The structure of the message of your help menu when a user invokes the /help command

help_message_TIP: ""

The structure of the message of your help menu when a user invokes the /help tip command

help_message_SEND: ""

The structure of the message of your help menu when a user invokes the /help send command

help_message_GIVEAWAY: ""

The structure of the message of your help menu when a user invokes the /help giveaway command

help_message_WITHDRAW: ""

The structure of the message of your help menu when a user invokes the /help withdraw command

help_message_BALANCE: ""

The structure of the message of your help menu when a user invokes the /help balance command

help_message_GENERATEQR: ""

The structure of the message of your help menu when a user invokes the /help generateqr command

This was everything you can specify in your settings.yml. Adjust to your needs.

BotFather Setup (Commands)

When creating your new bot, remember to set up the commands of the new bot.

You must at least have these commands, paste them into the BotFather PM when asked to specify the commands:

help - Print help
tip - <username> <amount>
send - <address> <amount>
withdraw - <your private wallet address>
balance - Show your current balance
giveaway - <amount>
generateqr - <amount>
Installation

You can compile every main.go you see here if you want and use only the binary. But we will stick to the source code here.

Clone repo
git clone https://github.com/monero-ecosystem/telegram-monerotipbot
Install dependencies (using golang modules)

Install ZMQ library (eg. on Debian based systems)

sudo apt install libzmq3-dev

Now install all golang dependencies with one command:

go mod tidy

If you are on go1.17 you can use:

go mod tidy -compat=1.17
Bot

Start the bot and specify the settings file:

cd cmd/
go run main.go -c ../settings.yml

The bot is considered to be safe in errors. To reduce interruptions while operating it on eg. a VPS, let it run in a loop so it "restarts itself" should there be anything wrong (mostly due to Telegram itself), if at all:

cd cmd/
while true; do go run main.go -c ../settings.yml; done
Notifier

To notify users create a file which holds the message you want to send or broadcast and send it with the notifier:

cd cmd/notifier

vi message.txt
...
<write down the message in that file and save it>
...

Send to specific user:

go run main.go -messagefile message.txt -c ../../settings.yml -userid 123456

Broadcast to all users:

go run main.go -messagefile message.txt -c ../../settings.yml -broadcast

You can also redirect the output of this operation to a file:

go run main.go -messagefile message.txt -c ../../settings.yml -broadcast 2>&1 > broadcast.log

LabelMapper

There is a label mapper to gather all labels from the wallet and save it to a local file. The label mapper just issues a walletrpc.GetAccounts() and dumps the object into a json file:

cd cmd/labelmapper
go run main.go -c ../../settings.yml

It will save it to a file named labelmap.json.

Hint: If you use the statsd client, you will get labels in your statsd backend, which is more comfortable since you don't have to run this LabelMapper in a cron or by hand.

Questions

If you have questions or trouble feel free to create an issue in this repository so we can help you.

Final Notes

YOU (the bot operator) are dealing with money here, at least when you are not operating on stagenet. With power comes responsibility.

If you use this bot in your own group, people trust you by depositing their Monero to your wallet. Do not abuse their trust!

  • If you create a new wallet, write down and save away the mnemonic seed of that wallet.
  • Do regular backups of the wallet. You can broadcast a "scheduled maintenance" message to all users. On that date, stop the bot, stop the wallet-rpc daemon, and make a backup of the wallet file and store it somewhere safe. Restart all services again after that.

Contribution

  • You can fork this, extend it and contribute back.
  • You can contribute with pull requests.
