Starknet, an Ethereum layer-2 solution, has announced plans to become the first layer-2 network to facilitate transactions on both Bitcoin and Ethereum. This initiative aims to enhance the interoperability and scalability of Bitcoin, allowing users to access decentralized finance (DeFi) services directly on the Bitcoin network. Starknet's features include increased transactions per second (TPS), two-second block times, and low gas fees of $0.002. The integration will be supported by Xverse, a Bitcoin wallet that is expanding its services to Starknet, enabling cross-chain swaps between Bitcoin and Starknet assets. Additionally, users will be able to utilize the Lightning Network for transactions, allowing payments with STRK at Lightning-enabled vendors. Starknet's strategic plan includes establishing a Bitcoin reserve fund to further unify the two largest blockchains, thereby enhancing their functionalities and maintaining decentralization principles.
