On March 11, the Ethereum Layer 2 network Starknet’s development team StarkWare announced the launch of a new STRK20 framework, designed to provide built-in privacy features for stablecoins and other digital assets while maintaining regulatory compliance capabilities. The system is expected to be officially deployed on the Starknet network later in 2026 and is seen as an important technological upgrade to promote privacy-focused DeFi infrastructure development.
According to StarkWare, the core design of the STRK20 framework is to embed privacy functions directly into the token itself, rather than relying on external privacy tools. Through this mechanism, on-chain account balances and transfer information can be hidden from the public, enhancing user data protection in blockchain financial activities. At the same time, the framework remains compatible with the common ERC-20 token standard on Ethereum, allowing developers to issue privacy-enabled assets without altering existing DeFi ecosystems.
STRK20 is also designed to support various on-chain financial scenarios, including transfers, exchanges, staking, and other common DeFi operations. Developers can add privacy features to tokens without deploying complex infrastructure, which helps lower the barrier to developing privacy-focused financial applications.
On the regulatory front, STRK20 introduces a “view key” mechanism. This allows access to be granted to regulators, auditors, or law enforcement agencies under legitimate procedures, maintaining compliance while protecting user transaction privacy. StarkWare CEO and Zcash co-founder Eli Ben-Sasson stated that privacy should not be an optional feature in blockchain finance but a fundamental attribute at the token level. He believes this model could significantly accelerate the adoption of stablecoins within the financial system.
StarkWare also indicated that the STRK20 framework has been optimized for performance. The system aims to achieve approximately five-second transaction settlement times and keep individual transaction costs below $0.20. This design is expected to help stablecoin issuers and institutional users more efficiently test privacy payments and on-chain settlement solutions.
At the application level, StarkWare has proposed several potential use cases, including privacy stablecoins to reduce front-running, settlement systems that hide payroll data in corporate payments, and institutional DeFi trading activities. Additionally, the framework will integrate with Starknet’s recently launched Bitcoin-related asset strkBTC, supporting balance masking and confidential transfers.
As market demand for blockchain solutions that combine privacy protection with regulatory compliance continues to grow, the STRK20 framework could open new technological pathways for stablecoin payments, enterprise settlements, and institutional DeFi, positioning Starknet as a more prominent player in the privacy financial infrastructure space.

Aave Faces a Major Trust Crisis: Service Providers Exit En Masse, with “Technology, Governance, and Risk Control” Fully Failing
Author: Jae, PANews
Compared with the external pressure of a bear market, Aave has instead seen a “black swan” emerge internally first.
Aave, which has long occupied the throne of lending agreements, is now facing the most severe ecosystem shake-up since its founding. There has been no hacker attack, no code vulnerabilities—only power gone out of control and conflicting interests.
From BGD Labs, a technical cornerstone, decisively leaving, to a public break between governance pioneer ACI (Aave Chan Initiative), and then to Chaos Labs, the risk-management steward, announcing that it is parting ways— a major “service provider retreat” is unfolding.
The depth of this game goes far beyond a mere cooperation dispute; it has triggered
