Starknet launches STRK20 for private token transfers and privacy features for USDC on its network

Starknet has introduced the STRK20 framework, enabling users to shield supported ERC-20 tokens and transfer them privately without revealing sender, recipient, amount, or token type. This privacy feature is live on Starknet's mainnet following the v0.14.2 upgrade, which added proof-verification infrastructure for private transactions. The first asset on STRK20, strkBTC, is backed by Bitcoin and supports both public and shielded modes. Additionally, privacy features for USD Coin (USDC) were launched, allowing shielded balances and private transfers while maintaining standard ERC-20 compatibility. Users can also share transaction details selectively via viewing keys. Separately, Ztarknet is a proof-of-concept project aiming to enable private programmable execution on Zcash but remains in early development. Over $2 million in assets have been processed privately on Starknet, with 56 assets included in its unified privacy pool, signaling growing adoption of blockchain privacy tools.

Starknet's new token privacy features provide context for cryptocurrency market activity. For readers following major cryptocurrencies, here is Pluang's market snapshot as of Oct 18, 2026 22:21 WIB: out of 50 major cryptocurrencies, 4 rose and 44 fell.
