📝 UniCloak

UniCloak is a unified, compliance-aware privacy protocol that enables private transfers, swaps, bridging, and cross-chain swaps through a single shared liquidity pool. By combining zk-identity, private wallet commitments, and relayer-based execution, UniCloak breaks the link between depositors and recipients while remaining compatible with existing DeFi infrastructure.

The Problem

Public blockchains leak financial privacy by default. Wallet histories reveal donations, trading strategies, payroll, treasury movements, and personal payments. Existing privacy tools (mixers, shielded pools, etc.) are limited because they:

• stop at withdrawal and break DeFi composability

• fragment liquidity across chains

• offer no compliance-aware identity layer

This prevents sensitive, regulated, or institutional use cases from adopting on-chain finance.

Core Idea

UniCloak treats privacy as a programmable execution layer, not a dead-end mixer. It introduces three primitives:

1. zk-Identity (zk-KYC)
   Users generate a zero-knowledge identity commitment from passport data locally in-browser. No PII is stored on-chain. The long-term vision integrates biometric ePassports with ICAO/PID-SOD validation for cryptographic authenticity, enabling compliance without surveillance.

2. Private Wallet Commitments
   Wallets are Poseidon hashes of (nullifier, secret, balance) stored in a Merkle tree. State updates occur via ZK proofs, not public addresses.

3. Unified Private Pool on Mantle
   Liquidity sits in a single pool that serves as a privacy hub, rather than fragmenting anonymity across multiple chains or pools.

Private DeFi Execution

Instead of exposing addresses, users authorize actions via ZK proofs, while relayers submit transactions on-chain:

• Private Transfers (unlinkable withdrawals)

• Private Swaps via WooFi (Pool → WooFi → Recipient)

• Private Bridging via Stargate (Pool → Stargate → Destination)

• Private Cross-Chain Swaps (Pool → Stargate → CrossMessenger → WooFi → Recipient)

All without revealing the user’s wallet, identity, or deposit origins.

Compliance-Aware

zk-Identity enables users to prove they are eligible (have a valid passport, meet residency/age rules, etc.) without revealing the document itself. This creates a path for:

• institution-friendly liquidity

• regulated cross-chain trading

• private payroll and treasury ops

• donations and NGO funding
  without mixing-style legal baggage.

Why Mantle

Mantle provides an ideal base for UniCloak due to:

• low execution costs

• liquidity-first ecosystem vision

• cross-chain orientation
  UniCloak turns Mantle into a privacy settlement hub for multi-chain liquidity.

In One Sentence

UniCloak enables compliant, privacy-preserving DeFi from a single liquidity pool, extending privacy beyond withdrawals into swaps, bridging, and cross-chain execution.
