+# Argochain Security Audit Report
+
+**Date**: June 16, 2025   
+**Auditor**: Pavon Dunbar    
+**Scope**: Complete Argochain codebase security review    
+**Severity Levels**: Critical | High | Medium | Low    
+
+## 🚨 Executive Summary
+
+This security audit of the Argochain blockchain codebase has identified **multiple critical vulnerabilities** that pose significant risks to the network's security and user funds. The audit reveals several issues that could lead to:
+
+- Unlimited token minting/theft
+- Denial of service attacks
+- Memory safety violations
+- Replay attacks on cross-chain operations
+
+**⚠️ RECOMMENDATION: This codebase is NOT ready for production deployment and requires immediate security fixes.**
+
+---
+
+## 🔴 Critical Vulnerabilities
+
+### 1. Signature Verification Vulnerability in Cross-Chain Transfers
+
+**Severity**: 🔴 **CRITICAL**  
+**Location**: `frame/pallet-counter/src/lib.rs:179-237`  
+**CVSS Score**: 9.8 (Critical)
+
+#### Description
+The EVM to Substrate transfer function contains a critical signature verification flaw that allows replay attacks and signature forgery.
+
+#### Vulnerable Code
+```rust
+let message = format!("Transfer {} AGC from 0x{:x} to Substrate", amount_u128, evm_address);
+let prefix = "\x19Ethereum Signed Message:\n";
+let message_len = format!("{}", message.len());
+let message_to_sign = format!("{}{}{}", prefix, message_len, message);
+```
+
+#### Vulnerabilities
+- **Replay Attack**: No nonce or timestamp in signed message
+- **Cross-Chain Replay**: Same signature can be reused across different contexts
+- **Weak Message Construction**: Predictable format makes forgery easier
+- **Missing Context**: No block hash, chain ID, or recipient validation
+
+#### Impact
+- Attackers can replay signatures to drain EVM balances multiple times
+- Cross-chain signature reuse possible
+- Potential for unlimited token minting
+
+#### Recommended Fix
+```rust
+let message = format!("Transfer {} AGC from 0x{:x} to {} on chain {} at block {} nonce {}", 
+    amount_u128, evm_address, substrate_account, chain_id, block_hash, nonce);
+```
+
+---
+
+### 2. Unsafe Memory Operations
+
+**Severity**: 🔴 **CRITICAL**  
+**Location**: `precompiles/src/evm/handle.rs:118`  
+**CVSS Score**: 8.5 (High)
+
+#### Description
+Unsafe memory transmutation without proper lifetime validation could lead to memory safety violations.
+
+#### Vulnerable Code
+```rust
+unsafe {
+    EVM_CONTEXT::using(
+        core::mem::transmute::<&'a mut dyn PrecompileHandle, &'static mut dyn PrecompileHandle>(
+            precompile_handle,
+        ),
+        mutator,
+    )
+}
+```
+
+#### Impact
+- Memory safety violations
+- Potential use-after-free vulnerabilities
+- Runtime crashes or undefined behavior
+
+#### Recommended Fix
+- Implement proper lifetime management
+- Use safer alternatives to `transmute`
+- Add comprehensive lifetime annotations
+
+---
+
+### 3. Panic-Based DoS Vectors
+
+**Severity**: 🔴 **CRITICAL**  
+**Location**: `frame/evm/precompile/modexp/src/lib.rs` (multiple lines)  
+**CVSS Score**: 7.5 (High)
+
+#### Description
+Multiple panic calls in precompile code can be triggered by attackers to crash the runtime.
+
+#### Vulnerable Code
+```rust
+panic!("Modexp::execute() returned error"); // TODO: how to pass error on?
+```
+
+#### Impact
+- Runtime crashes through crafted EVM calls
+- Denial of service attacks
+- Network instability
+
+#### Recommended Fix
+- Replace all `panic!()` calls with proper error handling
+- Implement graceful error recovery
+- Return appropriate error codes instead of panicking
+
+---
+
+### 4. Insufficient Access Control for Critical Functions
+
+**Severity**: 🔴 **CRITICAL**  
+**Location**: `frame/pallet-counter/src/lib.rs:80-105`  
+**CVSS Score**: 9.0 (Critical)
+
+#### Description
+Critical mint/burn functions rely solely on root access without additional security measures.
+
+#### Vulnerable Code
+```rust
+#[pallet::call_index(0)]
+pub fn mint(origin: OriginFor<T>, account: T::AccountId, amount: SubstrateBalanceOf<T>) -> DispatchResult {
+    ensure_root(origin)?; // Only check - no additional validation
+    T::SubstrateCurrency::deposit_creating(&account, amount);
+    Ok(())
+}
+```
+
+#### Impact
+- If root is compromised, unlimited token minting is possible
+- No rate limiting or amount restrictions
+- Single point of failure
+
+#### Recommended Fix
+- Implement multi-signature requirements
+- Add time delays for large operations
+- Implement amount limits and rate limiting
+- Add emergency pause functionality
+
+---
+
+## 🟠 High-Risk Issues
+
+### 5. Integer Overflow/Underflow Risks
+
+**Severity**: 🟠 **HIGH**  
+**Locations**: Multiple files including `frame/base-fee/src/lib.rs`
+
+#### Issues Found
+- Base fee calculations can overflow (`BaseFeeOverflow` events)
+- U256 to u128 conversions can truncate values
+- Arithmetic operations lack proper bounds checking
+
+#### Recommended Fix
+- Use saturating arithmetic operations
+- Add proper bounds checking for all numeric operations
+- Implement comprehensive overflow protection
+
+---
+
+### 6. Insufficient Input Validation
+
+**Severity**: 🟠 **HIGH**  
+**Location**: `frame/pallet-counter/src/lib.rs:258-300`
+
+#### Description
+Message validation in transfer functions is easily bypassed.
+
+#### Vulnerable Code
+```rust
+let blacklisted_words = ["scam", "fraud", "hack", "illegal", "phishing"];
+// Simple string contains check - easily bypassed
+```
+
+#### Impact
+- Bypass content filtering with simple character substitution
+- No proper length validation
+- Missing encoding validation
+
+#### Recommended Fix
+- Implement regex-based content filtering
+- Add proper input sanitization
+- Implement comprehensive validation rules
+
+---
+
+### 7. Precompile Security Gaps
+
+**Severity**: 🟠 **HIGH**  
+**Location**: `precompiles/src/precompile_set.rs`
+
+#### Issues
+- Complex recursive call handling without proper bounds
+- Insufficient gas cost validation
+- Missing access control for sensitive operations
+
+#### Recommended Fix
+- Implement proper recursion depth limits
+- Add comprehensive gas cost validation
+- Implement role-based access control for precompiles
+
+---
+
+## 🟡 Medium-Risk Issues
+
+### 8. Unsafe RPC Method Exposure
+
+**Severity**: 🟡 **MEDIUM**  
+**Locations**: Multiple RPC modules
+
+#### Description
+Several "unsafe" RPC methods are exposed that could leak sensitive information.
+
+#### Recommended Fix
+- Review all RPC method exposure
+- Implement proper authentication for sensitive methods
+- Add rate limiting for RPC calls
+
+---
+
+### 9. Database Error Handling
+
+**Severity**: 🟡 **MEDIUM**  
+**Location**: `client/db/src/parity_db_adapter.rs:26`
+
+#### Vulnerable Code
+```rust
+panic!("Critical database error: {:?}", e);
+```
+
+#### Impact
+- Database errors cause runtime panics
+- No graceful degradation
+
+#### Recommended Fix
+- Implement proper error handling for database operations
+- Add retry mechanisms for recoverable errors
+- Implement graceful degradation strategies
+
+---
