[Starknet Launches STRK20 Privacy Framework to Support Private Transfers of ERC20 Assets] According to The Block, Starknet has launched the zero-knowledge privacy framework STRK20, providing balance shielding and private transfer capabilities for any ERC20 assets on the network, with initial implementation on strkBTC. This framework allows developers to introduce privacy features for scenarios such as transfers, exchanges, lending, staking, payments, and donations without the need to build a separate privacy system. STRK20 embeds a 'shielding' mode within the asset pathway instead of using the traditional mixer structure, and introduces a viewing key mechanism to selectively disclose specific wallet information only upon receiving legally valid requests, balancing privacy protection with compliance requirements.
