🛡️ PermaGuard

Your Autonomous Privacy Guardian for Web3

x post : https://x.com/ARPITSI86059796/status/2007769688345112891

The Problem You Face Every Day

Every Web3 transaction leaves permanent, public breadcrumbs:

  • Swap on Uniswap? Your trading patterns are now public and linkable across addresses

  • Transfer funds repeatedly? Anyone can fingerprint your behavior and identify all your wallets

  • DeFi farming? Your entire balance and strategy are visible to competitors, scammers, and data brokers

Current privacy tools require you to:

  • Manually execute obfuscation transactions (and remember to do it)

  • Grant risky unlimited approvals to third-party protocols

  • Possess deep technical knowledge to avoid mistakes

The result? Most users simply accept privacy leaks as the cost of using Web3.

The Solution: Set It and Forget It Privacy

PermaGuard is an autonomous privacy agent that protects your wallet 24/7—without requiring constant approvals or technical expertise.

Think of it as:

  • A VPN for your wallet (but fully on-chain)

  • A privacy bodyguard that never sleeps

  • An automated defense system with strict rules you control


How It Works in 3 Steps

1. Grant Limited Permission (One Time)

Connect MetaMask and authorize PermaGuard using Advanced Permissions (ERC-7715):
"Allow up to 50 USDC per week for privacy actions, valid for 30 days"
These permissions are:

  • Time-bound → Automatically expire

  • Amount-limited → Can never exceed your budget

  • Instantly revocable → One-click emergency stop

  • Enforced on-chain → No trust required

2. PermaGuard Monitors & Acts Autonomously

Once activated, PermaGuard's intelligent agent network continuously:

  • Detects privacy risks in real-time (pattern clustering, address linking)

  • Executes defensive actions automatically (obfuscation swaps, address rotation, fund routing)

  • Operates entirely within your pre-approved limits

Example Scenario:
You make 5 swaps in an hour → Risk: Transaction fingerprinting detected

→ PermaGuard automatically performs a small obfuscation swap using 10 USDC of your allowance

→ Your transaction graph is now harder to analyze

→ No popup, no manual intervention needed

3. Stay in Control with Full Transparency

Your dashboard shows:

  • Active permissions and remaining budget

  • Every action PermaGuard has taken (fully auditable on-chain)

  • Real-time privacy score

  • One-click revoke button


2. Agentic Architecture (Core Innovation)

PermaGuard uses a hierarchical agent swarm:

🔹 Master Guardian Agent

  • Holds the user’s primary permission

  • Enforces global limits and safety policies

🔹 Scout Agent

  • Monitors wallet activity and exposure signals

  • Uses indexed on-chain data (via Envio) to detect privacy risks

🔹 Shield Agents (A2A Delegation)

When risk is detected, the Scout Agent re-delegates micro-permissions to specialized agents:

  • Obfuscation Agent – breaks transaction linkability

  • Routing Agent – changes fund flow patterns

  • Rotation Agent – moves assets to ephemeral addresses

This agent-to-agent (A2A) permission flow demonstrates a real-world use of Advanced Permissions beyond simple automation, directly aligning with hackathon goals.


3. Autonomous Privacy Actions (No Re-Signing)

Once permissions are granted:

  • PermaGuard executes defensive transactions automatically

  • No repeated wallet pop-ups

  • No user intervention mid-flow

  • Every action remains auditable and constrained

Example:

A burst of swaps risks address fingerprinting → PermaGuard performs a small obfuscation swap within allowed limits.


4. Transparency & Control

The user dashboard shows:

  • Active permissions and remaining allowance

  • All executed actions (on-chain)

  • Real-time privacy status

  • One-click revoke / emergency stop

Revoking permissions immediately halts all activity.


Envio Integration (Best Use of Envio)

PermaGuard uses Envio HyperSync to index and query:

  • User transaction events

  • Permission grants, redemptions, and revocations

  • Agent-executed transactions

  • Balance and exposure patterns

Envio enables:

  • Real-time risk detection

  • Fast GraphQL queries for the UI

  • A transparent, auditable action timeline for users and judges

The demo explicitly shows Envio queries powering risk detection and monitoring.


Why PermaGuard Is Unique

  • Proactive, not reactive privacy protection

  • First agent-based privacy mesh using ERC-7715

  • Real A2A permission re-delegation

  • Strong focus on user consent, safety, and revocability

  • Combines Account Abstraction + Privacy + Agentic Systems

Most Web3 automation focuses on yield or trading.
PermaGuard focuses on protecting the user.


The Vision

Most Web3 automation focuses on maximizing yield or executing trades. PermaGuard focuses on protecting the user.

As blockchain adoption grows, privacy cannot remain a luxury for technical experts. PermaGuard makes privacy protection accessible, automatic, and safe—turning your wallet into a privacy-first fortress without sacrificing usability.
