STRK20 brings native confidential ERC-20 balances and regulated private transfers to Starknet

Starknet announced STRK20, a new token framework that embeds transaction privacy directly into ERC‑20 assets to provide confidential balances and private transfers without relying on mixers or external wrappers ^[1][3]. The design hides sender, receiver, token type, and transfer amount by default and leverages zero-knowledge proofs to enable on-chain private operations ^[3][4].

The framework is built to remain compatible with decentralized finance applications, enabling private swaps and staking while offering compliance controls intended to permit regulatory oversight where required ^[2][4][1]. StarkWare has targeted deployment on Starknet mainnet later this year, according to the announcement ^[3].

STRK20 positions privacy as a native capability on Starknet while explicitly aiming to balance confidentiality and regulatory compliance ^[1].
