[Starknet Launches Encapsulated Bitcoin strkBTC Officially Online] Starknet announced the launch of the privacy Bitcoin asset strkBTC on the Starknet network. Users can convert BTC into strkBTC within their wallets and use the "shield" feature to hide portions of their balance and transaction records. When necessary, they can "unshield" to restore the public balance. This feature is implemented based on Starknet's STRK20 privacy framework, which provides protocol-level privacy transfer support for any ERC-20 asset. The project team emphasized that strkBTC offers "auditable privacy," where users share a viewing key with independent third-party auditing institutions when enabling privacy, allowing for the provision of limited on-chain activity data under compliance requirements.
