Threshold Network has deployed its tBTC token on Starknet, allowing Bitcoin holders to mint native Bitcoin representations on the Ethereum Layer-2 network. This integration enables Bitcoin users to participate in decentralized finance (DeFi) applications with transaction fees as low as $0.01 while maintaining full custody of their assets.
Leveraging Starknet’s zero-knowledge rollup technology, the solution achieves near-instant transaction finality and supports up to 857 transactions per second. This addresses Bitcoin’s historical limitations of high fees and slow confirmation times, unlocking new utility beyond Bitcoin’s traditional store-of-value role.
tBTC integrates directly with Starknet’s DeFi ecosystem, including protocols like Ekubo decentralized exchange and Vesu lending platform. Users can engage in trading, borrowing, and complex financial strategies without relinquishing asset custody. The protocol utilizes threshold cryptography for decentralized asset management, eliminating single points of failure and counterparty risks.
Current Bitcoin participation in DeFi remains minimal at 0.3% of total supply. Industry analysts project tBTC’s Starknet deployment could increase Bitcoin’s DeFi utilization by 10-15x due to its cost efficiency and scalability advantages.
