🕶️ Private Cross-Chain Settlement

A private, intent-driven cross-chain execution layer bridging AVAX ↔ Algorand using darkpool-style settlement.

Not a bridge. Not a wrapper.
A shadow execution engine for moving value across chains without revealing sender, path, intent, or counterparties.

---

🚀 Overview

Modern bridges expose everything:

• sender
• receiver
• path
• liquidity
• mempool
• exact amounts
• timing
• intent

This repository is the first step toward solving that:

A private cross-chain settlement layer where the destination chain never sees the original sender or their intent.

This MVP demonstrates:

• Private intent submission
• Off-chain encrypted execution
• Hidden settlement path
• No destination-chain user signatures
• No mempool exposure
• No linkage between chains
• A dark relayer performing execution invisibly

🌑 What Makes This a Darkpool Primitive?

1️⃣ Intent-Based Submission

2️⃣ Private Off-Chain Relay Execution

3️⃣ Shadow Settlement

4️⃣ Zero Mempool Leakage

5️⃣ Path Obfuscation
