Great , i was looking for such types of the wallet .
Thanks for sharing this information , but this is strange that why yet not another people in my friend circle discussed about it .
Well thanks , I sent you a pm for further help
I just PMed you and replied back at email

.
Yeah , I heard about it by one of mine friend but I was confused due to segwit name with wallet .
Because I was thinking that segwit was fork name in Bitcoin , so I am getting either wrong information or not proper information .
Since I heard about green addresses , may be these are same type of wallet starting with prefix 3
Let me tell that I am right or not?
In my knowledge segwit address and green address are same , but there is only difference of prefix that start with "bc1" and "3" respectively .
But be careful not every address started with "3" will be bech/segwit adress .
Hope you understand .
