Lotline — September 30, 2026 technical tour. Caption-led, no narration. Actual local application footage; technical explanation slides are labeled. No generated UI, mocked wallet, purchase, signature or funds moved. Market observations are dated and may be unavailable. Example data is synthetic.

Precision starts with the budget.
Actual Example calculation. The extra micro-unit stays accounted for.

Freshness is part of the result.
Provider boundaries
A price is context. A quote is specific.
Issuer identity and on-chain mint checks come first.
Changing the budget or split clears old estimates.
Pyth references retain their timestamp and confidence.
Pyth may fall back or be unavailable. Expired references stay visibly stale; an earlier successful read cannot authorize a later purchase.

Pre-IPO has its own planning path.
Actual PreStocks screen. Discovery does not promise a purchase route.

Validate before the wallet signs.
Supported xStocks routes
The unsigned message has to match.
Check the wallet, mints, exact amounts and allowed programs.
Bound slippage and fees; validate the transaction instructions.
Simulate the unsigned message, then require wallet approval.
Current validator scope is direct Raydium CLMM through Metis for supported scaled xStocks. This slide is an explanation, not a transaction or proof that every asset can settle.

Uncertain is not complete.
Recovery
Stop. Reconcile. Then continue.
Persist the original signature before submission.
Pause later approvals when the outcome is unknown.
Confirm the original transaction and actual token movements.
Historical unsigned simulation and mocked recovery tests are separate evidence. Neither proves a real purchase. No wallet was connected and no funds moved in this recording.
