🥷 Shinobi Cash

Cross-Chain Privacy Pools for the Multi-Chain World

🎯 Vision

Shinobi Cash revolutionizes blockchain privacy by enabling users to deposit on any EVM chain and withdraw privately on any other chain through a single Arbitrum deployment. Built on enhanced Privacy Pools with regulatory compliance features, Shinobi Cash eliminates expensive custom relayers by leveraging Account Abstraction paymasters, reducing withdrawal costs by 50-80%.

"Making Arbitrum the privacy hub for all Ethereum users"

🥷 Shinobi Cash: The Cross-Chain Future

🚀 Comprehensive solution
✅ Cross-chain deposits and withdrawals
✅ 50-80% lower transaction costs
✅ No custom relayer dependency
✅ Single deployment serves all EVM chains
✅ Account Abstraction integration
✅ Regulatory compliant with ASP proofs

💡 Key Problems Solved

🎯 Problem 1: Expensive & Unreliable Custom Relayers

Current Issue:

❌ Users depend on third-party relayers
❌ High fees (bc of relayer profit markup)
❌ Relayers may go offline
❌ No standardized infrastructure

Shinobi Solution:

✅ Account Abstraction Paymasters✅ 50-80% cost reduction✅ Reliable, standardized infrastructure✅ No third-party dependency

🎯 Problem 2: Fragmented Cross-Chain Privacy

Current Issue:

❌ Want privacy on 10 chains? Deploy protocol contracts on 10 chains
❌ Liquidity fragmentation
❌ Higher operational costs
❌ Complex user experience

Shinobi Solution:

✅ One Arbitrum deployment serves ALL chains
✅ Unified liquidity pool
✅ Seamless cross-chain experience
✅ Arbitrum becomes privacy hub

🎯 Problem 3: Limited Withdrawal Options

Current Issue:

❌ Can only withdraw on deposit chain
❌ No cross-chain flexibility
❌ Requires separate bridging
❌ Multiple transaction costs

Shinobi Solution:

✅ Deposit from anywhere, withdraw to anywhere
✅ Single transaction experience
✅ OIF-powered cross-chain execution

🚀 Real-World Use Cases

• Receive payments privately across any chain

• Pay employees across chains privately

• Move funds between chains discretely

• Private business-to-business payments
