We have seen many people complaining that they had mistakenly sent bitcoins or any cryptocurrency to an address which they didn't want to.
Many times hackers hack other's wallets and steal their cryptocurrencies.

Everybody knows what an OTP is. It adds an extra layer of security in your payments.

What if we developed a wallet and integrated the OTP feature in it which basically when approved broadcasts the transaction on the blockchain ?
In my opinion this would add a layer of security. OTP doesn't need to be centralized and hence it won't break the decentralization part of bitcoin (but obviously a centralized wallet can still break it)
