Accessibility Bench Runner

Read-only by construction. The runner only reads the interface: one GET per scan, zero wallet or contract writes, and it never asks for a key, password, or payment. Every fetch is logged below so you can verify that yourself. Checks are pure functions of the page HTML — same input, same verdicts, every time.

Fixtures:

Contract address (optional):

Interface URL (optional — overrides fixture):

That contract address is not a valid 0x + 40-hex address — it will be ignored.

Pick a fixture or enter a URL, then run the checks.

Scan traffic (verify: GET only)

no scan yet

What the runner checks

Keyboard reachability — no tabindex="-1" traps; controls keyboard-reachable.
Visible focus — :focus-visible/:focus styles present.
Contrast — detected text colors vs background, WCAG AA ≥ 4.5:1.
Mobile layout — <meta name=viewport> present; no fixed width over 480px.
Key requests — visitor-facing private-key / seed-phrase language is flagged.
Payment requests — visitor-facing payment / card language is flagged.
Write actions — every contract write must explain its target and arguments in nearby text.

Honest limits: this is static HTML analysis — it cannot compute true rendered contrast or drive real keyboard focus. The verdict schema matches the acceptance test suite so any browser-rendered bench can be compared 1:1. Malformed or unreachable inputs surface as bounded error cards, never a crash.
