 Why Starknet? Starknet is a permissionless decentralized ZK-Rollup operating as an L2 network over Ethereum. Major applications such as MakerDAO, Aave and others are deploying contracts on Starknet and are putting resources into building on top of the platform. Moreover Alchemy, Argent, Infura, Ledger, and OpenZeppelin are taking part in building it.
 
-Not only this, do you know Starkware the company behind Starknet created zk-STARK (Scalable Transparent Arguments of Knowledge)? The same is famous for its security and privacy. Starknet offers eventual L1 security and it’s total value locked is $63.48 M.

-To begin with, Starknet is a Layer-2 scaling solution for Ethereum. Why the need to scale, though? Tbh, Ethereum is congested. Everyone and anyone is on that chain, and we hate to break it you, being there costs plenty of gas fees.
