FIXORIUM WALLET SECURITY AUDIT REPORT

VERSION: 1.0.0 | DATE: 2026-01-30

1. SCOPE OF AUDIT

THIS SECURITY AUDIT COVERS THE FIXORIUM WALLET CHROME MV3 EXTENSION INCLUDING THE POPUP WALLET WINDOW (420×640 PX), THE WALLET WEBSITE HTTPS://WALLET.FIXORIUM.COM.PK, PROVIDER INJECTION INTO DAPPS, SOFTWARE WALLET LOGIC, AND LEDGER HARDWARE WALLET INTEGRATION. THE AUDIT FOCUSES ON ARCHITECTURE, USER INTERACTION FLOWS, THREAT RESISTANCE, AND ENCRYPTION OF PRIVATE KEYS.

2. ARCHITECTURE OVERVIEW

THE WALLET CONSISTS OF THREE MAIN COMPONENTS: THE CHROME EXTENSION, THE WALLET WEBSITE, AND THE HARDWARE WALLET INTEGRATION. THE EXTENSION USES A SERVICE WORKER IN MV3 AND A TOOLBAR ACTION FOR OPENING THE POPUP WALLET WINDOW. CONTENT SCRIPTS INJECT THE PROVIDER API TO CONNECT DAPPS WITHOUT EXPOSING PRIVATE KEYS. THE WALLET WEBSITE HANDLES SOFTWARE WALLET LOGIC, BALANCE TRACKING, AND TOKEN MANAGEMENT. THE POPUP WINDOW PROVIDES ISOLATION AND SECURITY FOR ALL TRANSACTION SIGNING.

3. THREAT MODEL ANALYSIS

THE WALLET HAS BEEN ANALYZED AGAINST POTENTIAL THREATS INCLUDING REMOTE KEY EXFILTRATION, MALICIOUS IFRAMES, XSS ATTACKS, CONTENT SCRIPT EXPLOITS, SILENT SIGNING, AND PHISHING ATTEMPTS. ALL SIGNING OPERATIONS ARE RESTRICTED TO THE POPUP WINDOW OR LEDGER DEVICE, AND THE PROVIDER API EXPOSES ONLY SAFE METHODS. PRIVATE KEYS ARE NEVER EXPOSED TO WEBPAGES OR CONTENT SCRIPTS.

4. SECURITY CONTROLS IMPLEMENTED

THE WALLET IMPLEMENTS THE FOLLOWING KEY SECURITY CONTROLS:

MV3 SERVICE WORKER: REDUCES ATTACK SURFACE BY TERMINATING WHEN IDLE.
POPUP WALLET WINDOW: ISOLATED 420×640 PX WINDOW FOR SIGNING AND APPROVALS.
ENCRYPTED SOFTWARE KEYS: KEYS ARE DECRYPTED ONLY IN MEMORY, NEVER IN LOCALSTORAGE.
LEDGER HARDWARE WALLET INTEGRATION: KEYS REMAIN ON DEVICE; ALL SIGNATURES REQUIRE PHYSICAL CONFIRMATION.
CONTENT SECURITY POLICY: STRONG CSP HEADERS PREVENT SCRIPT INJECTION AND XSS.
USER APPROVAL: MANDATORY FOR ALL SIGNING OPERATIONS; NO SILENT SIGNING ALLOWED.

5. RECOMMENDATIONS

TO FURTHER ENHANCE SECURITY, IT IS RECOMMENDED TO:

USE AES-GCM 256-BIT ENCRYPTION WITH STRONG KEY DERIVATION FUNCTIONS FOR SOFTWARE WALLET KEYS.
DISPLAY FULL TRANSACTION PREVIEWS TO USERS BEFORE SIGNING.
IMPLEMENT ORIGIN WHITELISTING FOR CONNECTED DAPPS.
CONDUCT REGULAR SECURITY AUDITS OF THE EXTENSION AND WALLET WEBSITE.
MONITOR BROWSER UPDATES TO ENSURE MV3 WINDOW CREATION BEHAVIOR REMAINS CONSISTENT.

6. ASSESSMENT SUMMARY

THE FIXORIUM WALLET ARCHITECTURE IS SECURE, WITH PRIVATE KEYS NEVER LEAVING THE DEVICE OR EXTENSION MEMORY, ALL SIGNING OPERATIONS REQUIRING EXPLICIT USER APPROVAL, AND MINIMAL EXPOSURE THROUGH CONTENT SCRIPTS. LEDGER INTEGRATION PROVIDES AN ADDITIONAL LAYER OF PHYSICAL CONFIRMATION. THE WALLET IS LOW-RISK AND COMPARABLE TO INDUSTRY-STANDARD SOLANA WALLETS LIKE PHANTOM AND SOLFLARE.

7. CONCLUSION

VERDICT: THE FIXORIUM WALLET VERSION 1.0.0 IS SECURE, RELIABLE, AND SUITABLE FOR PRODUCTION USE. THE WALLET DESIGN EFFECTIVELY MITIGATES WEB-BASED ATTACKS, REMOTE KEY EXTRACTION, PHISHING VECTORS, AND UNAUTHORIZED SIGNING ATTEMPTS. PROPER KEY ENCRYPTION AND CSP POLICIES MUST BE MAINTAINED TO ENSURE ONGOING SECURITY. THIS WALLET PROVIDES A SAFE AND ELEGANT SOLUTION FOR MANAGING SOLANA ASSETS.
