Status

🔴 NOT IMPLEMENTED — No quote-based deployment or extension path exists in frontend.

Must-Have Tasks

#	Task	Type	Contract Function	Current State
5.1	Add quote ingestion/selection UX	Feature	N/A	Not implemented
5.2	Validate signed quote payloads	Feature	N/A	Not implemented
5.3	Show quote expiry, cost, and operator set	Feature	N/A	Not implemented
5.4	Add create-from-quotes flow	Feature	Services.createServiceFromQuotes()	Not implemented
5.5	Add extend-from-quotes flow for active services	Feature	Services.extendServiceFromQuotes()	Not implemented

Files

• ../tnt-core/src/interfaces/ITangleServices.sol — contract interface
• ../tnt-core/src/core/Quotes.sol — quote logic
• apps/tangle-cloud/src/pages/blueprints/[id]/deploy/page.tsx — deploy page (add quote path)
• apps/tangle-cloud/src/pages/services/[id]/page.tsx — service detail (add extend path)

Test Criteria

• User can input/paste signed quote payloads
• Quotes are validated for signature, expiry, and completeness
• Quote details (cost, operator set, expiry) are clearly displayed
• Service can be created from valid quotes
• Active service can be extended from valid quotes
• Expired or invalid quotes show clear error messages before tx

Nice-to-Have

• Quote comparison view (multiple quote sets side-by-side)
• Quote request flow (request quotes from specific operators)
