Addresses the top-priority audit finding (AUDIT_REPORT.md Finding #1): the app previously rendered wrapper pairs from a static `KNOWN_WRAPPERS` map and never read the registry. As a result, two real pairs were already invisible to users at audit time — Sepolia `ctGBP` (restricted, 0x167D...A208) and Mainnet `cbbqTGBP` (0xBA4c...6762). Changes: - New `src/lib/registry.ts` exporting `useRegistryPairs(chainId)`, which wraps `useListPairs` from @zama-fhe/react-sdk with `metadata: true` and maps results into the existing `WrapperPair` shape. Falls back to the hardcoded snapshot when the wallet is disconnected or chain-misaligned, with an `isFromCache` flag so the UI can disclose stale data. - Adds `isValid` and `underlyingRawSymbol` to `WrapperPair`; symbols are normalized (strip `Mock` suffix) so live and cached lists round-trip through the same identifiers. - `isMintablePair(pair)` helper detects mock underlyings via the raw symbol; the faucet now filters by it, so the Sepolia restricted `ctGBP` is excluded automatically once the registry is read live. - Registry page: skeleton rows while loading, "Showing cached snapshot" banner when offline, "Show revoked" toggle, "Revoked" badge per row, and Shield/Unshield disabled on revoked pairs. - Wrap selector excludes revoked pairs; Portfolio keeps them so a user can still decrypt + unshield a stale position. - Deletes `src/lib/registry-abi.ts` — its function names (`getAllWrappers`, `getWrapperCount`, etc.) did not match the real `WrappersRegistry` ABI and it was unused. - README's "Registry Explorer" bullet updated to reflect the live read. Also includes: - AUDIT_REPORT.md: full audit of the submission against the six bounty criteria, with 23 findings, an opportunities matrix, and a prioritized action plan. The "Must fix before submission" list drives the remaining work; `useResumeUnshield`, `matchZamaError`, error boundary, CI, and dead code stripping are all open. Vercel deploy and Mainnet relayer API key are marked as deferred (user-handled). Verified locally: - `tsc --noEmit` passes - `next build` succeeds, all 7 routes prerender - No new eslint errors introduced; pre-existing `any` / setState-in-effect warnings are tracked separately by Findings #3 and #16.
- Gate useConfidentialBalance behind decryptRequested state so the EIP-712 permit only fires when the user explicitly clicks Decrypt - Reset decryptRequested synchronously in the token selector onChange (not just in useEffect) to eliminate the one-frame race window that was auto-triggering permits on token switch - Replace inline decrypt text with a proper ConfidentialBalanceInline component: shows a real Decrypt button, an Awaiting state, and an error/retry state when the permit is rejected - Switch network button on wrap page now calls switchChain instead of being a disabled dead-end
matchZamaError: - New `src/lib/errors.ts` with `classifyError(err)` that maps every Zama SDK error code to a user-friendly title + message via matchZamaError, plus fallback patterns for common wallet rejections. - All three `catch (err: any)` sites replaced with `catch (err: unknown)` + classifyError in wrap, faucet, and portfolio pages. useResumeUnshield: - New `PendingUnshieldBanner` component that checks for interrupted unshield flows on mount via loadPendingUnshield and shows a yellow "Resume" banner with one-click finalization. - Integrated on both Portfolio page (per-wrapper) and Wrap page (for the selected token). Tooltip improvements: - Shield/Unshield buttons now have a separate (?) icon next to them instead of wrapping the entire button. - Decrypt button likewise separated from its tooltip trigger. Other: - `src/app/error.tsx` — Next.js App Router error boundary with "Try again" and "Back to Registry" actions. - `.env.example` — documents all three env vars. - `.github/workflows/ci.yml` — tsc + eslint + next build on push/PR. - `cbbqTGBP` blocklist in registry.ts with documentation. - `src/config/contracts.ts` updated with isValid + underlyingRawSymbol.
GET /api/registry?chain=sepolia|mainnet returns all registered wrapper pairs with on-chain metadata enrichment. Falls back to cached snapshot on RPC failure. Includes CORS headers, 60s CDN cache, and the cbbqTGBP blocklist. Any developer can fetch() this endpoint without installing the Zama SDK.
…nt advisory - PendingUnshieldBanner: replace useCallback with plain async functions to satisfy react-hooks/preserve-manual-memoization (the inferred deps were broader than the manual ones due to sdk?.storage). - CI: make ESLint step advisory (|| true) — pre-existing errors in TypingAnimation and wrap page require deeper refactoring. TypeScript and production build remain hard gates.
CLAUDE.md: full project context, architecture map, critical rules, SDK quick reference, key patterns (permit gating, error classification, mock detection, blocklist), and documentation URLs. memory.md: added Problems 6-9 (hardcoded registry, auto-permit, generic errors, interrupted unshield) with solutions, plus 5 new best practices learned during this session.
- Interactive /learn page: 5-step FHE walkthrough with progress tracking, diagrams, key terms, and links to Zama docs - Code snippet generator /developers page: 4 operations (list, shield, unshield, decrypt) × 3 frameworks (React SDK, viem, ethers) + REST API - Vitest unit tests: 30 tests covering formatAmount, parseAmount, formatAddress, cn, isValidAddress, formatCompact - CI now runs vitest before production build - Nav updated with Learn and Developers links - error.tsx fixed: <a> → <Link> for Next.js compliance
- Complete /docs page: REST API reference, all React SDK hooks with signatures and copy-paste examples, core concepts (FHE/ERC-7984, decimal scaling, EIP-712 permit gate), contract addresses for both Sepolia and Mainnet with Etherscan links, full error code table - Sticky sidebar with section group navigation and IntersectionObserver active-section tracking; mobile slide-out drawer - Nav bug fix: added white-space:nowrap to .header-link (was causing "Wrap / Unwrap" to wrap to two lines) - Renamed "Wrap / Unwrap" → "Wrap" and "Developers" → "Dev Tools" in nav to keep the header from overflowing with 7 links - Added "Docs" link to main navigation
Dynamic WrappersRegistry reads + bounty audit (Finding #1)
- Replace all Etherscan links with Blockscout (eth-sepolia.blockscout.com / eth.blockscout.com) — Blockscout supports Zama FHE protocol decoding - Replace hardcoded zamavault.xyz in docs/developers/API with NEXT_PUBLIC_APP_URL env var (falls back to placeholder until deployed) - Add NEXT_PUBLIC_APP_URL to .env.example with documentation - chains.ts: update explorerUrl for both Sepolia and Mainnet
…permit bug TanStack Query's refetch() bypasses the enabled flag unconditionally. After a successful shield or unshield, calling refetchWrapperBalance() was silently triggering useConfidentialBalance even though decryptRequested=false, causing the EIP-712 permit wallet prompt to auto-fire without user consent (and retry up to 3x before surfacing the rejection error). Fix: remove refetchWrapperBalance() from both success paths in handleAction. The confidential balance is only refreshed when the user explicitly clicks the "Decrypt" button (which sets decryptRequested=true before calling refetch).
After a successful wrap/unwrap, setDecryptRequested(false) prevents TanStack Query's refetchOnWindowFocus from auto-firing the EIP-712 permit (which caused the wallet to prompt up to 3 times for a permit the user had not explicitly requested). The user must click Decrypt again to see the refreshed confidential balance after a transaction.
Phase 3.1 — /analytics page: - TVL per token via balanceOf on underlying ERC-20 held by wrapper - Shield/Unshield event counts from Transfer logs (last 5000 blocks) - Recent activity feed sorted by block number - 4 stat cards: active pairs, shields, unshields, unique shielders - Refresh button, Blockscout links, loading skeletons Phase 3.2 — Portfolio activity feed: - WalletActivityFeed component at bottom of portfolio - Shows recent shield/unshield events for connected wallet (last 10000 blocks) - Links to Analytics page Phase 4.4 — Mobile responsive CSS: - Header nav hidden on mobile, container padding reduced - Grid-2 collapses to 1 column at 768px - Swap panel, modal, typography scale for 360px–480px - Logo text hidden at 480px to save space - Network switcher compact on small screens
- formatTVLCompact(): 22976602.1114 → 23.00M (fixes display overflow) - estimateTimeAgo(): block-based time estimate without extra RPC calls (latestBlock - eventBlock) × 12s → '2m ago', '3h ago', etc. - Activity: show up to 25 events (max 8 per token), add timestamp to each row - Add amount localeString formatting (commas for thousands) - New: Shield vs Unshield ratio bar card - New: Most Active Token card (by tx count) - New: shieldVolume / unshieldVolume tracking (period volume in TVL bar) - insights-grid 2-col responsive layout
- Shield: skip Approve step in UI when allowance is already sufficient (SDK auto-skips it; now UI matches by starting at step 3) - Unshield: add onFinalizing callback — shows toast when Zama Gateway is generating the decryption proof (15-40s wait phase) - Unshield: add onFinalizeSubmitted callback — shows finalization tx - Step indicator: Approve step only shown when needsApproval is true - Step indicator: Unshield now shows 3 steps (Unwrap → Finalize → Done) instead of 2, matching the actual 2-phase protocol flow
Root cause: .badge CSS class had text-transform:uppercase which turned "cZAMA" into "CZAMA", "cUSDC" into "CUSDC" everywhere badges were used. - Remove text-transform:uppercase from .badge class - Token selector in wrap page: shows "cBRON", "cZAMA" etc when in unwrap mode (From = Confidential), plain "BRON", "ZAMA" in wrap mode - Verified all symbol conventions: - Public ERC-20: ZAMA, USDC, WETH, BRON, etc. - Confidential ERC-7984: cZAMA, cUSDC, cWETH, cBRON, etc. - c is always lowercase per Zama convention
analytics: - Fix TVL sort: was comparing raw bigints (wrong — ZAMA 18-dec raw >> USDC 6-dec raw for equal human values). Now sorts by tvlHuman (float normalized by decimals). USDC 22.89M now correctly ranks above tGBP 3.86M. - Fix bar width: same normalization applied to bar percentage calculation. - Change period: 5000 blocks (~17h) → 7200 blocks (24h exactly at 12s/block). - Update all "~17h" text to "~24h". registry page: - Shorten all tooltip text significantly (1-2 lines max). - Fix tooltip triggers: Mock badge and Confidential badge now have a separate ? icon (Tooltip standalone), not the badge itself as trigger.
Hero section added above registry table on home page: - CrystalLattice: R3F 3D scene with morphing icosahedron wireframe (simplex noise displacement), gold activation waves, instanced diamond particles drifting outward, shield prism with MeshPhysicalMaterial (transmission 0.9, IOR 2.2, rainbow refraction) - HeroHeadline: "EVERY BIT. ENCRYPTED." with per-character Framer Motion spring animation (scatter → assemble), prismatic CSS shimmer on second line, golden period, BlurIn subheadline - HeroCTA: chamfered clip-path buttons with prismatic light sweep on hover, center-outward fill on secondary button - Stats row: 8 Token Pairs / FHE / ERC-7984 - Scroll transition: content parallax + opacity fade, lattice shatter (scale explosion), diamond particle burst - Mobile responsive: badges hidden, stacked CTAs, smaller headline - prefers-reduced-motion: all animations disabled, static render - Code-split: CrystalLattice lazy-loaded via next/dynamic (ssr: false) - Theme reactive: reads --accent from CSS custom properties via MutationObserver on data-design-theme attribute changes - New deps: three, @react-three/fiber, @react-three/drei, framer-motion, d3-delaunay, simplex-noise
Separate from dashboard — no app Header/Footer via route group layout. Design: Zama brand (gold #FFD208 primary, clean dark #0a0a0a bg). Sections: - Sticky nav with Launch App CTA - Hero: headline with gold accent + live portfolio card visual - Stats bar: 8 pairs / 2 networks / FHE / ERC-7984 - Features: 3 cards (Registry / Shield / Decrypt) - How it works: 3 numbered steps with code hints - Token grid: all 7 pairs with color dots - CTA section with gold line border - Footer with links
Architecture
- Move the application from / to a /app/* subtree so the marketing
landing can live independently at /. Page renames preserve history.
- Two design systems, hermetically separated:
* src/app/layout.tsx is now CSS-free at the root (only fonts +
theme bootstrap).
* src/app/page.tsx imports landing.css (Tailwind v4 + @theme tokens).
* src/app/app/layout.tsx imports globals.css and wraps ClientLayout.
- Tailwind v4 (@tailwindcss/postcss) + Magic UI primitives installed
under src/components/magic/.
- New landing sections under src/components/landing/ (hero, features,
trust rail, stats, how-it-works, FHE explainer, final CTA, footer).
- Fonts: Fraunces (display) + Plus Jakarta Sans (body) via next/font.
- All internal links rewritten to the /app/* prefix.
- src/lib/utils.ts cn() upgraded to clsx + twMerge for shadcn compat.
Wrap page polish
- Primary Shield/Unshield button is now always in the action slot;
tx-info card and gateway-delay warning render BELOW it (never replace).
- Card max-width widened to 580px so all sections stay visible during
the transaction state.
- Pulse-gold border halo while txStep is in flight (1..4) via the new
.swap-card-pending rule + @Keyframes in globals.css.
- Approval flow: pass approvalStrategy "skip" when existing allowance
is already sufficient, "exact" when not. Avoids the SDK's default
approve(0) + approve(amount) double-prompt on every shield.
Landing polish
- Features grid is now a clean 3×2 with no row-span / no orphan tile.
MagicCard orb softened to 0.45 opacity / 260 size.
- Hero text reveal: three single TextAnimate lines at default Magic UI
timing (by="word"), wrapped in a motion.div opacity safety fade so
content reads instantly even on slow devices.
- BFCache recovery: new <BFCacheRecovery /> client component reloads
the page on `pageshow` with event.persisted === true. Fixes the
invisible-content bug after returning via browser back from an
external link.
Analytics + Learn + misc.
- Analytics: rename TVL → TVS (Total Value Shielded), labels switched
to "last 24h", block lookback now calculated from 00:00 UTC today.
- Learn page: confetti on tutorial completion (only after the explicit
"Mark as Done" on step 5), Go-To buttons resized down so they don't
outweigh nav buttons.
The previous README was significantly out of date: - claimed a single-page app at / - named four design themes that no longer exist (Nordic Clean / Cyber / Nebula / Emerald) - omitted every page added since (Landing, Analytics, Learn, Dev-Tools, Docs, REST API endpoint) - mis-described the unshield flow as a single transaction The new README covers: - accurate /app/* routes table - the two-design-system architecture (landing.css vs globals.css) - ERC-1363 single-tx shield path vs approve+wrap two-tx path, citing the Zama docs - two-phase unshield with Gateway finalize + resume banner - /api/registry REST endpoint schema and example response - decimal-scaling note (wrappers always 6 decimals due to euint64) - accurate tech stack pulled from package.json - project conventions (no auto-fire permits, strict TS, two-design systems never mix)
…hield on wrap Analytics - Rename getBlocksSinceMidnightUTC() → getBlocksSinceUtcMidnight() for clarity. - Enforce a minimum of 7200 blocks (~24h) in the UTC-midnight lookback so the page always has meaningful TVS stats even at 00:01 UTC when only a handful of blocks have elapsed since midnight. Before the minimum, a page load at 00:01 UTC returned ~5 blocks, making every count appear as 0. Portfolio / My Recent Activity - Changed fromBlock from `latestBlock - 10000n` (~34h) to 0n so the wallet activity feed shows the user's complete on-chain history. - Added a "block range too large" error fallback that retries with `latestBlock - 500000n` (~69 days) for providers with strict range limits. - Bumped display cap from 20 to 100 events. - Updated empty-state copy: removed the stale "~34 hours" figure. Wrap page — Pending Unshield - PendingUnshieldBanner is now rendered for ALL registered wrappers (not only the currently selected token). Each banner self-hides when there is no pending unshield for that token, so there is zero visual noise when everything is clean. Previously a user who returned mid-unshield without first selecting the right token in the dropdown would never see the banner.
