🔒 Privacy Builds Arrive

Starknet has introduced a **flat-fee privacy solution** for onchain transactions, charging just **4 STRK (approximately $0.12)** regardless of transaction size. **Key features:** - Same fee applies whether shielding $10 or $1 billion - No variable pricing based on transaction amount - Aims to make privacy practical and scalable for everyday use This pricing model contrasts with traditional approaches where larger transactions typically incur higher fees. The fixed-cost structure makes private transactions predictable and accessible across all transaction sizes. The solution addresses a key barrier to privacy adoption: cost-effectiveness at scale.

Starknet has released two integration options for developers building privacy features: **Integration Options:** - **Wallet API** (via starknet.js): Simplified approach where the wallet manages viewing keys and proofs automatically - **TypeScript SDK** (Apache 2.0): Full control over notes and proving for wallets and advanced integrators **What's Available:** The privacy stack enables shielded balances and private DeFi on mainnet. The STRK20 standard allows users to shield any asset in one click while maintaining compliance capabilities. Developers can now add privacy features with minimal integration work, while businesses can build confidential onchain solutions. The infrastructure supports practical privacy designed for real-world crypto use cases.

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 directly with existing DeFi infrastructure rather than creating fragmented liquidity pools.

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.
