Starknet has officially launched strkBTC, a Bitcoin-backed asset that enables private transfers on its layer-2 network using zero-knowledge cryptography. The token is backed 1:1 by BTC and is redeemable at any time, marking the first deployment of Starknet’s new in-protocol privacy infrastructure.
Unlike standard wrapped Bitcoin, strkBTC is designed with optional privacy. Users can shield balances and transactions, with a viewing-key mechanism that allows selective disclosure to regulators or auditors. This design, comparable to Zcash, aims to balance confidentiality with compliance, a feature that Starknet argues could attract institutional users concerned about front-running and competitive intelligence.
The bridge between Bitcoin and Starknet currently operates under a federated model managed by five independent institutions: Twinstake, NEAR Intents, Luganodes, UTXO, and Xverse. Starknet’s governance proposal SNIP-38 outlines a roadmap toward trust minimization, evolving to BitVM-based verification and eventually OP_CAT-style mechanisms.
Starknet’s total value locked stands at approximately $229.7 million, modest compared to leading L2s, making the strkBTC launch a strategic bet to attract new Bitcoin liquidity into DeFi. Bitcoin was trading around $80,786 at the time of the announcement, with the market sentiment index neutral at 49.
