Starknet Launches STRK20 Privacy Standard For ERC-20

Starknet introduced a privacy layer for ERC-20 tokens that hides balances and transfers by default. The feature targets institutional use cases that require confidentiality while maintaining auditability on public blockchains.

The system, called STRK20, was announced March 10 by Starknet developers. It allows token issuers on the network to deploy assets with built-in confidential balances and private transfers. Users can shield tokens into a private state, move them without exposing transaction data, and later return them to a public state when disclosure is required.

Starknet said the design preserves liquidity by keeping private and public states tied to the same asset. That avoids splitting markets into separate token versions, a common limitation in earlier privacy systems.

Can Privacy Tokens Meet Compliance Demands?

Public blockchains such as Bitcoin and Ethereum prioritize transparency. Anyone can inspect wallet balances and transaction flows on block explorers, which improves verification but often deters institutions managing sensitive trading strategies or treasury activity.

Trillions of dollars move across public chains each year, yet transaction histories remain permanently visible. Could selective disclosure become the compromise that satisfies both regulators and institutional users?

STRK20 attempts to answer that tension through compliance controls. Transaction details can be revealed to authorized parties, including regulators, auditors, or accountants, if legally required. The model keeps everyday activity private while preserving an auditable record when oversight demands it.

Early integrations are already planned inside the Starknet ecosystem. Privacy-enabled swaps are expected on Ekubo Protocol, and developers are exploring confidential staking for assets including Bitcoin and the Starknet token.

The initiative builds on earlier privacy experiments by the network. Starknet introduced strkBTC earlier this year, a Bitcoin representation that allows optional shielding while still interacting with decentralized finance applications.

Interest in privacy infrastructure is increasing as institutional activity grows in decentralized finance. Yet regulators continue scrutinizing systems that obscure transaction data, particularly in the United States and European Union.

Still, Starknet’s approach differs from fully anonymous privacy networks by allowing selective disclosure rather than permanent secrecy. The next signal will come from developer adoption and whether exchanges, custodians, and compliance teams support STRK20 integrations.
