NOS Telegram Tip Bot
# BANANO Telegram Tip Bot


Thank you for using my services @NOSTipBot! Below is a list of commands, and a description of how you can interact with me:
- .tip
- .help
- .register
- .account
- .withdraw

• !help: The NOSTipBot will respond to your DM with a list of commands and their functions. If you forget something, use this to get a hint of how to do it!n
# Install

• !register: Creates a fresh NOS (XNOS) account address specifically for you. This is used to store your tips. Make sure to withdraw to a private wallet, as the tip bot is not meant to be a long term storage device for NOS (XNOS).
`cp config/example_config.ini config/webhooks.ini`

• !balance: This shows you how much funds are in your your account.
Specify postgres user/schema/port/host

• !tip: Tips are sent directly to @username on telegram. Tag @NOSTipBot and mention !tip <amount> <@username>. EXAMPLE: @NOSTipBot !tip 1 @user will send a 1 NOS (XNOS) tip to another user.
Copy tipbot.service example to systemd

• !account: Returns the account number. You can use this to deposit more NOS (XNOS) to tip from your personal wallet.

• !withdraw: Proper usage is !withdraw nos_12345. This will send the full balance of your tip account to another external NOS (XNOS) account. Optional: You can include an amount to withdraw by sending !withdraw <amount> <address>. Example: !withdraw 1 nos_123 would withdraw 1 Nos to account nos_123
Run with systemd
