Description from store The TCVS Extension enables secure communication between credit union applications and the U.S. Treasury's Check Verification Service API by automatically handling Cross-Origin Resource Sharing (CORS) restrictions. Built for financial institutions using Corelation Keystone systems to integrate with Treasury check verification services, specifically optimized for TTCU Technologies custom UI scripts. ### KEY FEATURES: ✓ Automatic CORS bypass for Treasury API calls ✓ Domain-restricted operation (tcvs.fiscal.treasury.gov only) ✓ Zero configuration required - works immediately upon installation ✓ Advanced debug logging system with centralized controls (v2.0.0) ✓ Complete Firefox browser support with Manifest V2 (v2.0.0) ✓ Cross-browser API bridge with seamless communication (v2.0.0) ✓ Enterprise-grade domain restriction and whitelist functionality (v2.0.0) ✓ Storage persistence for debug states and extension settings (v2.0.0) ✓ Real-time request monitoring and statistics ✓ No data collection or external communication ✓ Minimal permissions and performance impact ### WHAT'S NEW IN v2.3.5: ✓ Seamless Permission Experience - Auto-injection after permission grant ✓ Enhanced ExtJS RunScript Support - No manual retry needed ✓ Consistent Version Display - Fixed version mismatch in popup UI • Automatic Content Script Injection: When permissions are granted, scripts automatically inject into all tabs - no page reload required • Smart Permission Detection: UI scripts automatically detect when permissions are granted and update status in real-time • Improved RunScript Context Support: Better handling of dynamically created ExtJS RunScript iframes • Enhanced API Validation: Better detection of invalidated extension contexts to prevent false "Active" status • Service Initialization Handling: Added retry logic for "Service initializing" errors with automatic recovery • Version Consistency: All components now show the correct version number using npm version scripts ### HOW IT WORKS: Once installed, the extension automatically handles CORS restrictions when your credit union application makes API calls to the Treasury Check Verification Service. It works seamlessly in the background with no additional setup required. The extension ONLY activates for requests to tcvs.fiscal.treasury.gov, ensuring your other web browsing remains unaffected. ### SECURITY & PRIVACY: • Minimal permissions model with Treasury API access only • No user data collection • No external communications beyond Treasury API • User-controlled site access via optional permissions ### TECHNICAL REQUIREMENTS: • Chrome 88 or higher • Works with Corelation Keystone systems • Compatible with TTCU Technologies UI scripts This extension is specifically designed for financial institutions and requires appropriate Treasury API credentials to function.
