Starknet Launches STRK20 Framework for Private ERC-20 Transfers
Public blockchains expose wallet balances, counterparties and transaction histories, creating privacy risks for individuals as well as institutions seeking to protect treasury activity or trading strategies. StarkWare-developed Ethereum Layer 2 network Starknet designed STRK20 to add shielded balances and confidential transfers to existing ERC-20 assets. The framework uses zero-knowledge proofs to verify transactions without publicly revealing sensitive details, while retaining compatibility with Starknet wallets, liquidity and decentralized-finance applications.
StarkWare said STRK20 went live on Starknet’s mainnet on June 9, 2026. Assets deposited into its privacy pool are represented by encrypted notes, and private transfers conceal the sender, recipient and amount while remaining verifiable onchain. Encrypted viewing keys provide a route for narrowly scoped disclosure in response to valid legal or regulatory requests. The first live use case is strkBTC, a wrapped Bitcoin asset that allows users to activate privacy features on Starknet.

The history behind this eventStarkWare Introduces Privacy-Preserving Identity Verification on Starknet
StarkWare develops zero-knowledge-proof technology for blockchain scaling, while its Starknet platform is an Ethereum Layer 2 network. Traditional know-your-customer checks often require platforms to retain complete passport, address and other personal data. A database breach can therefore expose personal information on a large scale, making the balance between regulatory compliance and privacy a major issue for financial services.
StarkWare has unveiled a "Private KYC" demonstration system on Starknet that lets users verify specific qualifications with zero-knowledge proofs without disclosing their full passport details or address—for example, by proving they are at least 18 years old. The company has not disclosed a formal launch date, commercialization timetable or financial figures, but the project demonstrates a viable way to reduce the exposure of sensitive data in on-chain identity verification.
