**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.
