Hinkal CEO Presents Architecture Session on Private Stablecoin Payments

Hinkal showcased confidential, verifiable stablecoin payments during a Day One session on Arc's public testnet. The demonstration highlighted their privacy infrastructure that keeps wallet balances, transfers, and counterparties hidden while maintaining on-chain verifiability. **Key features:** - Institutional-grade privacy for stablecoin transactions - Invisible wallets with confidential balances and transfers - Instant finality without intermediaries - On-chain verification maintained despite privacy layer Hinkal is building universal privacy infrastructure for public blockchains, positioning private stablecoin payments as a default standard rather than an optional feature.

**Hinkal's Private Send** has been featured in Bankless for bringing practical on-chain privacy to crypto users. **Key Features:** - Send funds privately without revealing your wallet address - Schedule transfers within randomized time windows - Support for unlimited recipients - No wallet migration required - Works with existing public wallets The solution addresses blockchain's transparency problem, where all transactions and balances are publicly visible. This creates privacy concerns for individuals and competitive disadvantages for institutions. Private Send uses zero-knowledge proofs and stealth addresses to keep sender information, amounts, and transaction history confidential while maintaining on-chain verifiability.

**DeFi cards are bridging crypto and real-world spending**, but they expose a privacy gap. [Ether.fi Cash](http://Ether.fi) lets users spend stablecoins while earning 5.6% APY or borrow against yield-bearing assets without selling crypto. **The privacy problem**: All blockchain transactions are public. When you fund a DeFi card from your main wallet, anyone can trace the connection between your spending and investment activities. **Hinkal Wallet offers a solution** - a self-custodial private smart contract wallet that breaks on-chain links: - Deposit funds into Hinkal's shielded pool - Unshield the amount needed for your Ether.fi Cash vault - Transfer completes with no traceable connection to your source wallet This **preserves financial privacy** while maintaining full DeFi functionality. Users can spend, borrow, and transact confidently without exposing their broader portfolio activity. As DeFi integrates deeper into everyday payments, privacy solutions like Hinkal become essential for users who value financial confidentiality in transparent blockchain systems.
