Description

The first on-chain untraceable, unidentifiable private payments on Mantle Network

Simply means: Stealth Crypto Payments using multilayer forks

🚨 The Problem: Financial Privacy is Broken

Real-Life Story

Alice, a legendary dev, won the Move AI Hack and received $13,000 prize money.

Bob, another participant who won another prize in the same hackathon, discovered his co-founder wasn't trustworthy about receiving prize money. Bob texted all 12 winners asking for the organizer's wallet address. Within minutes, using blockchain explorers and intelligence tools, he identified:

  • Which wallet belonged to whom

  • Exactly how much each person received

  • Their entire transaction history

This is a serious concern. Nobody wants their wallet exposed — it makes them vulnerable to targeted attacks, extortion, and financial loss.

The Core Issues

Payments on public blockchains are NOT private

  • Traceable through tools like Arkham Intelligence

  • Trackable via Dune Analytics and explorers

  • Identifiable by anyone with basic skills

Results:

  • Fear of transacting

  • Inconvenience for legitimate users

  • Financial loss from targeted attacks

  • Privacy violations for everyone


✅ The Solution: PrivatePay

Screenshot 2026-01-16 at 3 46 04 PM

Where every transaction is fully private, anonymous, unidentifiable, and untrackable.

Core Benefits

  • Sender privacy: Your wallet is never linked to the transaction

  • Receiver privacy: Recipients' identities remain hidden

  • Observer blindness: Third parties see nothing linkable

  • Simple UX: Like Stripe links, but every transaction is a new, invisible wallet

  • Level-based progression system


🚀 How It Works

Three-Step Process

1. Create Payment Link 🔗

  • User creates static payment link (e.g., amaan.privatepay.me)

  • System generates meta address (static identifier)

  • Link can be shared publicly without privacy risk

2. Receive Payment 💸

  • Payer accesses link → generates unique stealth address

  • Payment sent to stealth address on Mantle Network

  • Transaction is unlinkable to recipient's identity

3. Manage Funds 💰

  • Recipient monitors stealth addresses automatically

  • Funds can be withdrawn to main wallet

  • Full transaction history in private dashboard
