Starknet introduces STRK20, enabling any ERC-20 token to gain built-in privacy with zero-knowledge proofs and no extra integrations

Starknet has introduced STRK20, a privacy framework that lets ERC-20 tokens on Starknet support shielded balances and private transfers using zero-knowledge proofs, without requiring separate privacy infrastructure for each token. The system is designed so users can move assets into a shared privacy pool, transact privately, and later withdraw back into a transparent state while the network verifies correctness without revealing balances or full transaction histories. The main context is that Starknet’s earlier v0.14.2 mainnet upgrade added the native protocol support needed to verify these privacy proofs, making STRK20 practical at the network level rather than as a wrapper or workaround. Starknet says the framework also supports selective disclosure through viewing keys for lawful requests, which positions it as privacy infrastructure intended to balance confidentiality with compliance requirements. The first live application cited for STRK20 is strkBTC, a Bitcoin-backed ERC-20 that can operate in both public and shielded modes, showing how the framework is meant to extend privacy to existing tokenized assets and DeFi use cases.
