Hinkal Wallet Adding Private Key Import/Export for Public Accounts

**CryptoRubic has launched a beta version of its privacy solutions aggregator**, marking a significant development in the crypto privacy space. The platform integrates multiple privacy providers into a single interface, allowing users to directly compare: - Transaction speed - Cost - Confidentiality levels This aggregator approach addresses the fragmented nature of privacy tools in crypto by centralizing access and enabling side-by-side evaluation of different solutions. The beta is now available for users to test and compare privacy providers firsthand. [Try the beta](https://rubic.exchange/blog/web3-privacy-tools-the-state-of-2026/)

**Wallets are becoming the account layer for crypto neobanks, but there's a fundamental problem:** public wallets expose all financial activity by default. - Balances are visible to anyone - Counterparties can be traced - Transaction flows can be reconstructed over time **The core limitation:** While stablecoins scale access, they can't scale neobanks without privacy. Hinkal addresses this through: - Cryptographic privacy via smart contracts - Compliance built in (Chainalysis screening, viewing keys) - Multi-chain support (EVM, Solana, Tron) - Recipient-side privacy - not just sending The platform has processed $400M+ in confidential volume across products including Hinkal Wallet, Hinkal Pay, and Hinkal Send.

**Privacy infrastructure now available for Solana ecosystem** A privacy-focused infrastructure layer is now available for Solana wallets, applications, and protocols. The solution enables: - Confidential balances - Private receive functionality - Private payouts The infrastructure integrates into existing Solana stacks with minimal technical overhead. This builds on over three years of privacy tool development on Solana, including private sending, swaps, wallet funding, and payment APIs. The modular approach allows developers to add privacy features without rebuilding their applications from scratch.

**The Privacy Gap in Crypto Payments** Most privacy solutions protect senders but fail at the receiving end, leaving transactions exposed. **Key Issue:** - Current payment systems focus on sender anonymity - Receivers remain vulnerable to exposure - Transaction privacy breaks at the destination point **The Missing Piece:** True payment privacy requires protecting both parties - sender and receiver - not just one side of the transaction. This highlights a fundamental flaw in existing on-chain privacy approaches.

**Hinkal Pay** has launched, enabling businesses and consumers to settle transactions with full confidentiality. **Key Features:** - Sender, recipient, and amounts remain private on-chain - Works with existing wallets, chains, and stablecoins - Supports confidential sending, receiving, and payouts - Maintains compliance through Chainalysis screening **How It Works:** Funds move to a confidential balance within Hinkal's smart contract, controlled by the recipient's existing wallet. Recipients can execute private payouts to vendors, employees, or partners, or send to public wallets while keeping the sender private. **Availability:** - Live on Ethereum, Base, Arbitrum, Polygon, Arc, and Optimism - Supports USDT, USDC, DAI, and ETH - All transactions screened before execution; high-risk addresses blocked The service builds on Hinkal's earlier Private Send feature, which enabled private top-ups for non-custodial crypto cards through Ether.fi integration.
