Starknet is an layer 2 Ethereum chain. And it was developed to reduce the chain fees, scaling Ethereum by being bridge with other layered chain. There is also the feature of the staking, borrowing and the lending on the chain. You would surely find some interesting features being developed on the layer 2 recently. 

The new update says they are unifying the bitcoin and Ethereum layer and also settling on the bitcoin from this month onwards too. The update was shown on the twitter X. 

This move would allow the starknet developers to design the apps which would work with both the ethereum and the bitcoin. And this would also help them with the development with the bitcoin blockchain and also OP_CAT update has been good for the blockchain and for developers who wish to build apps on the chain. 

There are many benefits of this new update. Like for DeFi this would work good. And also the way things are working over it would mean that it can build the wallet and the services in much better way. Like the wallet has been good with the settlement for both bitcoin and ethereum based transactions. And DeFi and protocol based locks and the stake based apps would be fun too.
