According to ChainCatcher, Starknet clarified on the X platform about Starknet's entry into the Bitcoin extension layer: "Starknet will continue to focus on the expansion of Ethereum. Since the launch of Starknet, our goal has remained the same, that is, to develop STARK proofs to enhance the scalability and integrity of the blockchain we believe in.
No new layer (Layer) or new exclusive tokens will be created on Bitcoin. Instead, Starknet will try to serve as an execution layer that expands both Bitcoin and Ethereum. Its security, governance, and ecosystem will be driven by STRK tokens."
