Starknet Privacy Adoption Crosses $500K Milestone

**Multiple teams are building privacy-focused applications on Starknet using STRK20:** - **AVNU** - Trading and routing for STRK20 and private asset flows - **Troves** - Automated yield vaults with private deposits - **Forge Yields** - Cross-chain yield vaults exploring institutional-grade private allocation - **Provable Games** - Exploring private onchain organizations - **Invoicemate** - Building a private mainnet with one-click privacy toggle for lenders These developments follow earlier announcements about STRK20 expanding across the Starknet ecosystem, including open-source SDK access, a Proof of Privacy incubator, and private swaps through AVNU and Ekubo.

A new privacy solution allows users to perform **anonymous swaps** directly against existing liquidity pools without requiring isolated pools or cold starts. **Key features:** - Multi-call privacy enables users to unshield, swap, repay, and reshield assets in a single transaction - Works through existing signing keys via native account abstraction - no new wallet required - Users can shield assets in one click and control wallet disclosure - Builders can add private flows without rebuilding privacy infrastructure - Compatible with ERC-20 assets on Starknet without new token standards or wrappers - Designed for institutional use with confidentiality by default and customizable disclosure paths The solution addresses common privacy challenges by integrating with existing DeFi infrastructure rather than creating fragmented liquidity pools.

Developers now have two options for integration: **SDK (TypeScript, Apache 2.0)** - Designed for wallets and advanced integrators - Provides full control over proving and notes - Open-source implementation **Wallet API (starknet.js)** - Simplified integration for standard applications - Apps never handle viewing keys or proofs directly - Wallet manages all cryptographic operations This dual approach balances flexibility for power users with security and simplicity for mainstream developers.

Starknet has officially launched its privacy infrastructure for builders with the release of SDK and Wallet API tools. **What's New:** - Developers can now integrate privacy features into their applications using the new SDK and Wallet API - Shielded balances and private DeFi protocols are already operational on mainnet - The STRK20 standard enables users to shield any asset with one click **Key Features:** - Privacy layer works without requiring new token standards or wrapped assets - Built-in compliance layer for institutional use cases - Minimal integration work required for existing teams The infrastructure aims to bring practical privacy to crypto applications while maintaining compatibility with existing ERC-20 assets and DeFi protocols.

The Financial Privacy Inc (FPI) holds the master disclosure key within a dual-enclave Trusted Execution Environment (TEE), establishing a multi-layered security framework for Starknet's privacy infrastructure. **Key Security Measures:** - Primary protection: 3-of-4 multisig split between StarkWare and FPI - Secondary backup: 7-of-12 multisig controlled by Starknet Security Council - Disclosure only occurs through valid lawful requests assessed by FPI **Privacy Pool Operation:** - Users undergo screening upon entry to STRK20 Privacy Pool - All activity remains encrypted once inside - Selective disclosure limited to specific users, transfers, or time windows as legally required This architecture balances privacy protection with regulatory compliance through independent oversight.
