strkBTC Goes Live, Private BTC on Starknet

Starknet (STRK) · Releases & Updates · May 12, 2026

Starknet launches strkBTC on May 12 — the first wrapped Bitcoin with optional privacy, enabling shielded DeFi transactions at the protocol level via ZK proofs.

strkBTC is a wrapped Bitcoin asset on Starknet (Ethereum L2) that gives BTC holders optional privacy for their DeFi activity. Issued deterministically upon verifiable Bitcoin deposits — no custodian, no discretion. Users choose between public mode (standard ERC-20 behavior) and shielded mode (hidden balances and transfers). Privacy is built into the protocol via StarkWare's ZK technology, not reliant on mixers or third-party apps. strkBTC is also eligible for Bitcoin staking on Starknet — earn yield while keeping balances shielded. Designed to attract institutional capital that avoids public blockchains due to exposed positions and strategies. Global watch parties in London, Lisbon, NYC, Seoul, and Bengaluru on launch day.
