Starknet Bridges BTC and ETH on L2, Paving Way for Cross-Chain Expansion

12.03.2025 06:12
Starknet has announced its plan to bridge Bitcoin (BTC) and Ethereum (ETH) on a unified Layer 2 network, aiming to scale Bitcoin’s transaction capacity from a mere 13 transactions per second to thousands. The plan involves using Bitcoin as a settlement layer together with Ethereum, leveraging novel technical proposals like OP_CAT and alternatives such as BitVM. The initiative is backed by the Starknet Foundation and includes partnerships with key players such as Xverse, while influential voices like Ethereum co-founder Vitalik Buterin have expressed support for a secure Bitcoin Layer 2 solution. Additionally, Starknet’s native token (STRK) could gain traction from this integration, as the ecosystem looks to overcome Bitcoin’s programmability limitations and expand its financial use cases through the BTCFi Season program.
