The Bitcoin network has shown decent development since its launch decades ago. There is one sector that I think still lagged behind in terms of development: Wallet flexibility. Your wallet is your bank. So your wallet's flexibility is also as important as your wallet's security. This is where the idea of a smart wallet can play a significant role for the bitcoin network.
The core idea is to create a highly customizable wallet where its owner can set up or pre-define any rules they desire without losing control of their funds.
Why do I think this is important?
What if someone wants to lock his bitcoin for his future generation and wants to set up a lock for 10 years so that his children will not be able to transfer these funds for the next 10 years, or a business owner wants to pay his workers monthly salary in bitcoin and he doesn't want to log in every time he needs to do that? He just simply set up a contract that will send monthly salary to some predefined address every month. Another possible use case is to prevent any unwanted transactions from coming through. Like only whitelisted addresses can send funds to a specific address, transactions from any unknown address will not be mined in this way, and the receiver address can pay for the transaction fees. There are countless more possibilities for the use of a smart wallet, and I think this will be a much-needed development in the future. Also, using and securing manmonic phrases or privet keys seems inconvenient for many of us, so using NFT's or some other possible ways to make your bitcoin wallets back up grandma-friendly will be a major development for wide adaptation of the bitcoin network.
All these needs to be user friendly that non tech dude can set up this rules only by clicking few steps.
