Starknet introduced strkBTC on May 12, a zero‑knowledge Bitcoin token that hides balances and adds auditability, targeting DeFi users and institutional
Starknet’s Layer‑2 network rolled out strkBTC on May 12, a wrapped Bitcoin token that uses STARK zero‑knowledge proofs to conceal transaction amounts while still allowing regulated auditors to view activity when needed【1】. The launch aims to give Bitcoin holders a privacy option for DeFi without sacrificing compliance.

|---|---|
| Launch date | May 12, 2026 |
| Token type | ERC‑20‑compatible wrapped Bitcoin (strkBTC) |
| Privacy tech | STARK zero‑knowledge proofs, optional “shielded mode” |
| Compliance feature | Viewing keys for auditors, built‑in asset screening |
How strkBTC works
Users bridge BTC to Starknet and receive strkBTC, an ERC‑20 token that can be toggled into “shielded mode.” In this mode, balances and transfer amounts are hidden from public view, yet the network can still verify transaction validity through STARK proofs that require no trusted setup【1】. The privacy layer is optional; holders can switch it off to retain full transparency, distinguishing strkBTC from fully private coins like Monero or Zcash【1】.
Compliance and ecosystem support
Starknet embeds compliance tools directly into the token. Holders can share cryptographic viewing keys with auditors, enabling selective disclosure of transaction details. A built‑in screening layer also blocks assets linked to sanctioned addresses from entering the shielded pool【1】. Supported wallets such as Xverse and Ready X integrate the privacy functions natively, while bridges from Atomiq and Garden provide the on‑ramps for converting BTC into strkBTC【1】.
Competitive context
The wrapped Bitcoin market already hosts WBTC, tBTC, cbBTC and others, but none offer native zero‑knowledge privacy【1】. By combining Bitcoin’s value with Starknet’s ZK rollup, strkBTC targets a niche of DeFi users and institutions that need both confidentiality and auditability【2】. Its design could set a template for future Bitcoin‑based assets that must meet tightening AML requirements【2】.
What to watch
- Adoption metrics – volume of BTC bridged to strkBTC and usage on Starknet DeFi protocols.
- Regulatory feedback – any public statements from AML authorities on the token’s auditability model.
- Bridge activity – onboarding of additional bridge providers beyond Atomiq and Garden.
The launch of strkBTC marks Starknet’s shift from a pure scaling solution toward a privacy‑first layer‑2 that could attract institutional Bitcoin liquidity, provided the privacy‑compliance balance proves workable in practice.
