Complete Privacy Infrastructure for Cross-Chain DeFi
The Privacy Ecosystem: Shadow-swap (cross-chain bridge) + Veil Wallet (smart account interface)

THE PROBLEM
Cross-chain bridges are surveillance systems disguised as infrastructure. Every transaction exposes sender addresses, amounts, recipients, and timing patterns to the world. Users wait 10-30 minutes for confirmations while paying 0.5-2% fees, and their complete financial activity becomes permanently traceable on-chain.
Meanwhile, existing wallets force users to choose: Use standard wallets with zero privacy, or migrate entirely to siloed privacy solutions that lack critical features like transaction batching, account abstraction, and seamless public/private switching.
In an era of increasing blockchain analytics and regulatory scrutiny, financial privacy isn't a luxury—it's a necessity.
OUR SOLUTION: TWO PRODUCTS, ONE ECOSYSTEM
Shadow-swap: Privacy-Preserving Cross-Chain Bridge
The first privacy-preserving intent-based bridge combining zero-knowledge cryptography with competitive solver markets. Bridge assets in 60 seconds with complete privacy—no one can link deposits to withdrawals or trace activity across chains.
What sets us apart: While Across and UniswapX solved speed and capital efficiency, none integrated privacy-preserving cryptography. Shadow-swap fills this critical gap.
Veil Wallet: Smart Account Wallet with Dual Modes
Smart account wallet with dual public/private modes—choose transparency or privacy, transaction by transaction. Built on Account Abstraction (AA), Veil enables transaction batching, token swaps, and seamless switching between public and private transfers. All features available to all users—no premium tiers, no paywalls.
What sets us apart: First wallet to combine AA infrastructure with privacy-preserving cryptography. Users don't migrate to a new ecosystem—they add privacy as a feature to their existing DeFi workflow.
HOW THEY WORK TOGETHER
Current Integration (Launch State)
User opens Shadow-swap web platform
Connects Veil Wallet (like connecting MetaMask to any dApp)
Initiates private bridge transaction through Shadow-swap interface
Veil signs and submits the transaction with its smart account features
Shadow-swap's solver network processes the bridge in 60 seconds
User receives funds privately on destination chain
Why Use Veil with Shadow-swap?
Transaction batching: Bundle multiple bridge transactions to save gas
Smart account security: Social recovery, custom spending limits
Seamless experience: Native support for privacy transactions
Gasless bridging: Optional gas sponsorship for users
Future Integration (Q3-Q4 2025)
Bridge functionality built directly into Veil wallet interface
One-click private bridging without visiting separate platform
Integrated bridge + swap workflows (bridge USDC, automatically swap to ETH privately)
Advanced automation: Auto-bridge when gas prices drop, scheduled transfers
Today: Two products that work together (connect Veil to Shadow-swap web app)
Tomorrow: Fully integrated privacy ecosystem in one interface

Combined at scale ($1M daily bridge volume, $1M daily wallet volume):
Shadow-swap: ~$30K/month
Veil Wallet: ~$30K/month
Total:
$60K/month ($720K annual run rate)
Growth Drivers
Network effects: More solvers → better fills → more users → higher volume
Wallet users naturally become bridge users (integrated UX)
Swap functionality drives daily active usage and transaction volume
Integration partnerships with privacy-focused protocols
Solver incentives create organic marketing
WHY NOW
Market Timing

Why This Team
We're not theorists—we're builders who've shipped production Web3 products. Between KharonPay (payments infrastructure), Strimz (streaming platform), privacy engines, and on-chain applications, we've proven we can execute complex crypto projects. Our hackathon win validates our technical approach. We're hungry, experienced, and 100% committed to making Shadow-swap + Veil the privacy standard for cross-chain DeFi.
COMPLIANCE DECLARATION
Regulatory Status: Both Shadow-swap and Veil Wallet operate as pure decentralized infrastructure, similar to Uniswap or MetaMask.
Key Points:
✅ Non-custodial: Users maintain complete control of assets at all times
✅ No custody of funds: Smart contracts hold assets only during active transactions
✅ Permissionless: Anyone can use the bridge, wallet, or become a solver
✅ No regulated assets: Does not issue securities or regulated financial instruments
✅ Future governance token: Potential utility/governance token planned post-launch (not a security offering)
✅ Privacy tools, not anonymity service: Provides cryptographic privacy (like cash), not regulatory anonymity
Privacy vs. Compliance: Shadow-swap and Veil provide cryptographic privacy for legitimate use cases. We comply with all applicable decentralized infrastructure regulations.

Shadow-swap + Veil: Building the privacy-first future of cross-chain DeFi
Progress During Hackathon
During the hackathon, we built and deployed Shadow-swap, a privacy-preserving cross-chain bridge using intent-based settlement. We implemented the complete dual-contract architecture with PrivateIntentPool and PrivateSettlement contracts, integrated Poseidon hashing for zero-knowledge-friendly commitments, and built the off-chain Rust relayer infrastructure with separate coordinator services. We established the solver network flow, implemented ECIES encryption for secret management, and deployed functional contracts on testnet with working cross-chain transfers that preserve user privacy. In parallel, we developed Veil Wallet, a non-custodial smart account wallet built on Account Abstraction infrastructure. We implemented dual public/private mode operation, transaction batching capabilities, and full ERC20 token support with privacy-preserving transfers. Both products are functional and demonstrate how privacy-first architecture can be combined with modern DeFi infrastructure—proving that users don't have to choose between privacy and usability.
