DeFi cards are bridging crypto and real-world spending, but they expose a privacy gap.​ Ether.​fi Cash 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.​
