- Starknet launches BTC staking on mainnet (Sep 30), enabling Ethereum-based users to earn rewards by locking Bitcoin via ZK proofs without transferring assets off-chain.

- The feature expands cross-chain DeFi utility, addressing demand for Bitcoin integration in Ethereum-compatible environments while maintaining asset security.

- By enhancing liquidity and native asset support, the move positions Starknet as a multi-chain platform and sets a potential precedent for ZK protocols pursuing cross-chain interoperability.

The Layer 2 scaling solution Starknet is set to introduce

Bitcoin
(BTC) staking on its mainnet on September 30, marking a significant development in the interoperability between Ethereum-based protocols and the Bitcoin blockchain. The feature will allow users to lock BTC within the Starknet ecosystem to earn staking rewards, leveraging Starknet’s zero-knowledge (ZK) proof technology to ensure scalability and security. This move follows increasing demand from the DeFi community for cross-chain utility and exposure to Bitcoin within Ethereum-compatible smart contract environments.

The launch is part of Starknet’s broader strategy to expand its role beyond a scaling solution for

Ethereum
and into a multi-chain platform. By enabling BTC staking, Starknet aims to offer users a more versatile range of assets that can be utilized for yield generation, governance, and decentralized finance (DeFi) applications. The protocol has emphasized that the integration does not require users to move their BTC off the Bitcoin chain, addressing common concerns about asset security and custody.

According to developers and analysts, the BTC staking feature is expected to enhance liquidity within the Starknet ecosystem, especially for applications that require native asset support. The move also aligns with the rising interest in Bitcoin's utility beyond a store of value, with protocols increasingly exploring ways to integrate BTC into more complex financial products.

The mainnet launch of BTC staking comes after months of testing and validation within the Starknet testnet environment. Developers have stated that the feature has undergone extensive security audits and is now ready for public deployment. This timeline aligns with Starknet’s roadmap to continuously expand its capabilities and reinforce its position as a key player in the ZK space.

Analysts have noted that the launch of BTC staking on Starknet could set a precedent for future cross-chain integrations, potentially encouraging other ZK protocols to explore similar initiatives. The success of the feature will depend on user adoption, the efficiency of staking yields, and broader market demand for multi-chain DeFi solutions. If successful, it could further cement Starknet’s role in the evolving decentralized finance landscape.
