VEILFI

VEILFI is a decentralized yield aggregation protocol built on Mantle that enables users to deposit funds, earn optimized yields across multiple DeFi strategies, and maintain complete financial privacy through zero-knowledge cryptography.
Problem Statement

The Privacy Paradox in DeFi

The current DeFi ecosystem faces a critical privacy problem:

1. Complete Financial Transparency

Every transaction on blockchain is permanently visible. Your deposits, yields, balances, and entire financial history are exposed to anyone with a block explorer.

2. Security Risks from Exposure

Targeted Attacks: Wealthy wallets become prime targets for hackers and phishing
Front-Running: MEV bots exploit visible pending transactions
Social Engineering: Exposed wealth leads to real-world security risks

3. The Compliance vs Privacy Dilemma

Institutions require KYC/AML compliance to participate in DeFi
Current solutions force users to choose: full transparency OR no compliance
There's no middle ground for privacy with regulatory adherence

4. Fragmented Yield Strategies

Users must manually manage positions across multiple protocols
Capital inefficiency from scattered liquidity
No unified solution combining privacy + yield optimization

Solution

ZK-Yield: Where Privacy Meets Yield

We've built a protocol that solves all three problems simultaneously:

1. Zero-Knowledge Balance Proofs

Using ZK-SNARKs (Circom circuits), users can:

Prove they have sufficient balance for withdrawals
Verify compliance requirements without exposing amounts
Maintain complete financial privacy on-chain

2. Multi-Strategy Yield Aggregation

Single deposit → Funds allocated across multiple strategies
Auto-compounding → Yields reinvested automatically
Admin-controlled allocation → Risk-adjusted optimization

3. Privacy-Preserving Compliance

On-chain KYC verification without exposing personal data
ZK proofs validate compliance requirements
Satisfies regulatory needs while protecting privacy

How It Works

1. User connects wallet & completes KYC
   └── ComplianceManagerV2 marks address as compliant

2. User deposits funds to StrategyVault
   └── Funds automatically allocated across strategies

3. Strategies generate yield (Aave/Lido/Uniswap)
   └── Auto-compounded back into vault

4. User withdraws using ZK proof
   └── Proves sufficient balance WITHOUT revealing amount
   └── Privacy preserved at every step

The Result

Before ZK-Yield	After ZK-Yield
❌ Public balances	✅ Private balances
❌ Manual yield farming	✅ Automated optimization
❌ Privacy OR compliance	✅ Privacy AND compliance
❌ Fragmented strategies	✅ Unified vault

Value Proposition

"Earn DeFi yields with TradFi compliance and complete privacy."

VEILFI is not just another yield aggregator—it's the first protocol that treats financial privacy as a fundamental feature, not an afterthought.

For Retail Users: Protect your wealth from exposure while earning optimized yields.

For Institutions: Meet compliance requirements without sacrificing competitive advantages.

For DeFi: A new standard for privacy-preserving financial infrastructure.
