PANews reported on March 10th that Starknet released STRK20 privacy capabilities, providing account balance confidentiality and private transfers for any ERC-20 token (including BTC, stablecoins, ETH, etc.), and supporting free switching between "masked/public" states and private DeFi operations within the same asset. Any team can integrate this capability for ERC-20 tokens on Starknet, avoiding the isolation of assets in a separate privacy pool. STRK20 also incorporates compliance design, allowing selective disclosure of transaction information to auditors or regulators when legally required. The official description calls it the new default form of "privacy-native tokens" on Starknet.
