# GTIX migration engineering verification — September 11, 2026

The active Polygon store is `0x8e3cF290A1E5c434ec2F1bf2Dfe274539Abe1297` and the active token is `0xDe31319E2E21F2475FcC69eab72Ca8E30Fe92c5c`.

This migration uses the existing owner-mintable token and the 100× denomination of the catalog store. The store preserves the original settlement, inventory curve, proof validation, pause controls and cumulative spending accounting. Only GTIX monetary constants and the constructor-selected token/root differ. Direct deposits remain excluded from acquired stock and purchase authorization.

## Completed checks

- 83 automated tests passed. The separate 100× catalog/redenomination/owner-token run passed 18 tests.
- The complete five-step customer-paid approval/sale/custody-approval/token-approval/purchase cycle passed with the owner token and replacement store: 1-GTIX standard sale, 1,000-GTIX resale, no gas sponsorship and no collection-wide approvals.
- Six authentic Decentraland collections passed real-NFT sale/purchase and direct-deposit exclusion checks on a disposable current Polygon fork. Mainnet customer NFT trades were not submitted.
- All 9,337 eligible pricing proofs were verified. The other 1,399 designs remain blocked. Original evidence expiry is preserved.
- All six migration receipts were confirmed. Two Polygon providers verified deployed runtime hashes, owner, token, forwarder, treasury, custody address, root, budgets and prices.
- The old store and token are paused; the old store allowance is zero. Retirement checks confirmed all old GTIX remained in treasury and no acquired inventory or customer balance needed migration.
- Current review compiled ten sources, matched six Polygon deployed creation payloads/runtime hashes and checked three frozen Amoy runtimes. Current new-token ownership and store authority were verified.
- The public website and APIs agree on the active token, store and root. Both directly deposited wallet NFTs are excluded from purchase inventory. The updated scene is active at parcel (102,56).

## Limits

This is an engineering review, not an independent audit. A live customer signing/trading walkthrough is still unverified. Native customer-paid submission still requires a Polygon-capable wallet bridge; the previously observed Ethereum-only bridge uses a selected-wearable browser handoff. Sponsorship remains disabled.

The public RPC services could not provide the complete historical role-event range for the retired token during the additional audit. Current known role holders were checked against the preserved previous audit, and the retired token remains paused. This run does **not** claim a fresh complete enumeration of retired-token role history. The detailed report uses status `current-state-verified-history-incomplete` for that reason.

The previously recorded moderate Hardhat archive-tooling findings and the large Three.js demo bundle remain. Pricing evidence expires September 16, 2026 at 15:50:23 UTC; a renewal must use reviewed evidence and preserve cumulative counters.
