Hi!
I have developed a simple and secure block explorer telegram bot.
You can use it everywhere 
Now it supports next commands: balance and transaction. Also it doesn`t collect any information and statistic about users and their requests.
Bot is in alpha test now, please, report me any bugs and request new features.
Please, use the follow link https://t.me/chainexpbot and visit my mini website https://chainexp.com/
Thanks!
