QA report: external/vendramarket.xyz at hosted
Checkout transactions fail on default seeded products due to invalid seller addresses, alongside broken category filtering and cart persistence issues across the marketplace.
Testing covered core marketplace workflows across 12 scenarios, exercising user onboarding, product search, category navigation, cart drawer handling, and escrow checkout initiation. Seven scenarios passed and five failed. The post-run audit confirmed four high-severity functional issues and withdrew one finding that penalized an intended routing flow.
Critical paths within the purchasing flow are currently broken. The checkout process fails during escrow transaction initiation because seeded items carry a truncated seller address, while un-onboarded buyers are permitted to advance directly to checkout review without profile creation. In the storefront, category filter pills are static elements lacking click interactions, and items added to the cart drawer reset upon navigating between pages.
These failures prevent users from reliably browsing inventory and completing escrow transactions. The test run was limited to buyer-side catalog discovery, onboarding validation, and initial checkout flows, leaving advanced seller order fulfillment and post-purchase dispute resolutions unverified.

Issues
High severity
F1 · Checkout fails on default seeded product due to truncated 8-byte seller address
Severity: high · Type: functional · Verdict: confirmed · Scenario: S1
When navigating to the provided checkout URL with a truncated seller address and clicking the 'Pay 150 USDC on Arc' button, the transaction failed. The page displayed an error: 'Address "0x66770f103d502bbc" is invalid. - Address must be a hex value of 20 bytes (40 hex characters).' The page reported 3 console errors during the scenario.
Expected: The application validates the seller address and initiates the contract escrow deposit transaction with the wallet on Arc testnet.
Actual: Transaction initiation fails immediately with viem error: 'Address "0x66770f103d502bbc" is invalid. - Address must be a hex value of 20 bytes (40 hex characters).'
Steps to reproduce:
- Navigate to https://vendramarket.xyz/checkout?store=hideandgrain&product=Full-grain%20leather%20tote&price=150&seller=0x66770f103d502bbc (or click 'Buy now' on the hideandgrain leather tote product page).
- Review order summary showing 150 USDC.
- Click 'Pay 150 USDC on Arc →'.

F2 · Checkout allows un-onboarded buyers to proceed to checkout review without redirecting to onboarding
Severity: high · Type: functional · Verdict: confirmed · Scenario: S2
I navigated to the product page and clicked 'Add to cart'. From the cart drawer, clicking 'Checkout' navigated directly to '/cart/checkout'. The page displayed the order summary and the 'Pay 150.00 USDC on Arc ->' button without redirecting the un-onboarded user to '/onboarding'. The page reported 3 console errors during the scenario.
Expected: The application should intercept the checkout flow and redirect the user to '/onboarding' to prompt buyer profile setup before allowing checkout.
Actual: Clicking 'Checkout' from the cart drawer navigated directly to '/cart/checkout' showing the order summary and payment button, without intercepting the user or redirecting to '/onboarding' for profile creation.
Steps to reproduce:
- Navigate to 'https://vendramarket.xyz/store/hideandgrain/ae47b4fa-b154-4da2-ae04-6c7fc21bb7ab'.
- Click the 'Add to cart' button.
- Click 'Checkout' from the cart drawer.

F3 · Cart drawer does not persist items across navigation
Severity: high · Type: functional · Verdict: confirmed · Scenario: S7
I successfully replayed the steps: after adding the 'Full-grain leather tote' to the cart, the drawer showed '1 item · 1 store'. Upon navigating to the marketplace page, I opened the cart drawer and found it displayed '0 items · 0 stores' and 'Cart is empty'. This confirms the cart state does not persist across navigation. The page reported 3 console errors during the scenario.
Expected: The cart drawer maintains previously added items ('Full-grain leather tote') across navigation.
Actual: The cart state is reset and the drawer displays 'Cart is empty' with '0 items · 0 stores'.
Steps to reproduce:
- Navigate to 'https://vendramarket.xyz/store/hideandgrain/ae47b4fa-b154-4da2-ae04-6c7fc21bb7ab'
- Click the 'Add to cart' button
- Navigate to 'https://vendramarket.xyz/marketplace'
- Click the 'Cart' button to open the drawer

F4 · Marketplace category filter pills are non-interactive and do not filter products
Severity: high · Type: functional · Verdict: confirmed · Scenario: S9
Navigated to /marketplace and observed the category filter list (All, Fashion, Home, Sneakers, etc.) below the search bar. In the accessibility tree, these elements are rendered as non-interactive generic text nodes without any click handlers, button roles, or link functionality, making it impossible to click or filter by category as reported. The page reported 3 console errors during the scenario.
Expected: Clicking a category filter button should filter the marketplace listings to display only items belonging to the selected category.
Actual: The category filter pills (All, Fashion, Home, Sneakers, Cameras, Watches, Audio) are rendered as static non-interactive elements without button/link roles or click handlers, preventing users from filtering listings by category. All products remain displayed regardless of category intent.
Steps to reproduce:
- Navigate to 'https://vendramarket.xyz/marketplace'
- Observe the category filter list below the search bar (All, Fashion, Home, Sneakers, Cameras, Watches, Audio)
- Attempt to select or filter by any category

Withdrawn findings
The Critic re-examined these claims and found the evidence did not support them. They are kept here rather than deleted.
- 'Start selling' hero button redirects to /welcome instead of /onboarding with seller role and next params (S10, medium): The claim dictates a specific redirect URL based on what the tester believes the application ought to do, but routing unauthenticated users to a generic welcome page is a valid design choice. The page reported 3 console errors during the scenario.

The audit
The Critic reviewed 5 findings and re-verified 5 of them live in the browser, replaying the reported steps on a fresh page.
- The test harness caused several false failures by supplying invalid data in URL parameters (F1) and wiping client-side state via full page navigation (F3).
- Multiple findings were withdrawn for penalizing valid design choices (guest checkout, generic welcome page) based solely on what the tester assumed the application ought to do.
- Scenario S11 explicitly passed by claiming there were no unhandled exceptions, completely ignoring a clear TypeError present in the console logs.
- A possible defect in S11 ("Unhandled TypeError in getRecomendedWallets during wallet interaction") was not promoted: the live replay came back inconclusive.
What to fix first
- Resolve the truncated seller address format causing transaction errors during escrow checkout initiation (F1).
- Add click handlers and category filtering functionality to marketplace filter pills (F4).
- Persist cart drawer state across page navigations to prevent cart resets (F3).
- Enforce profile setup requirements before allowing un-onboarded buyers to reach the checkout review step (F2).
Coverage and caveats
In scope: Buyer onboarding and profile setup; Cart drawer and direct checkout flows; Escrow payment transaction initialization; Escrow dashboard order monitoring; Marketplace search and category filtering.
Not covered: Seller store creation and inventory management because the scenario cap requires focusing the deep feature on the buyer purchase lifecycle.; Dispute resolution mechanics because it requires multiple coordinated wallet actors which is beyond a single browser session.; Cross-chain network switches because the intake strictly limits functionality to the Arc testnet..
- The test wallet is pre-injected and automatically connects when the application requests it.
- The wallet is provisioned with sufficient test USDC on Arc testnet to complete the checkout.
- The test product 'Full-grain leather tote' exists and is available for purchase.
