SCALING BITCOIN + ETHEREUM TOGETHER

Summary from the TLDR Crypto newsletter

Starknet plans to become the first Layer 2 to settle on both Bitcoin and Ethereum. It uses ZK-STARKs to scale Bitcoin from 7 TPS to thousands, reduce fees to $0.002, and enable cryptographically-secured, trustless DeFi by early 2026. The Bitcoin bridge strategy will start with federated models, advancing to BitVM, and ultimately supporting OP_CAT for trustless bridging and withdrawal. The unified L2 approach will promote greater cross-chain liquidity and interoperability.
