feat(web): DApp for UniversalTimestamps by Copilot · Pull Request #28 · lightsing/uts

Copilot · 2026-02-25T05:10:36Z

Full web frontend for the UTS SDK — Ethereum-first timestamping DApp with file digest, stamping workflow, verification, upgrade, and real-time on-chain event feed. Supports wallet connection (EIP-1193), configurable chains/RPCs/calendars, batch directory stamping, and .ots file management.

SDK Changes

web3Provider support: Eip1193Provider on SDKOptions; verify() tries wallet provider first (auto chain-switch for well-known networks), falls back to ethRPCs
StampEvent callbacks: stamp() accepts onEvent callback firing per-phase progress (nonce → merkle → broadcast → calendar-response × N → proof → complete)
upgrade() keepPending option: When true, preserves pending attestation alongside upgraded one via FORK; default false purges it
WELL_KNOWN_CHAINS export: Chain ID → hex mapping for wallet_switchEthereumChain
Fix Scroll chain IDs: Corrected from 54351/54352 to 534351/534352 (0x8274f/0x82750)

Web App (`apps/web`)

Stack: Vue 3 + <script setup lang="ts">, Vite, Tailwind CSS v4, Pinia, VueUse, lucide-vue-next
Aesthetic: Cyberpunk minimalist — glassmorphism, neon cyan/purple accents, monospace hash display, CRT scanline effects
HeroTerminal: File picker + directory picker + drag-and-drop + manual hash input; digest computed on-demand (Keccak-256 default)
StampingWorkflow: Real SDK callback-driven pipeline visualization; manual download button for pending .ots; auto-download on upgrade
VerificationResult: Upload .ots + optional original file to verify header match; collapsible attestation details with etherscan links; recursive MerkleTreeViz proof path with inline attestation expansion
UpgradePanel: Manual upgrade tab for pending .ots files
LiveFeed: Real Attested event polling from both wallet provider and ethRPCs with dedup; collapsible entry details with tx links and Scroll logo
Wallet: Connect/disconnect MetaMask; address + chain display in header; provider auto-synced to SDK
Chain panel: Clickable "X/Y chains" in header → dropdown with per-chain status, latency, editable RPC endpoints, add/remove chains (z-index fixed above content)
Settings: Calendar URLs, internal hash algorithm, keepPending toggle — all persisted to localStorage
Batch stamping: Directory picker iterates files, stamps all, downloads as zip preserving directory structure
Testnet warnings: ⚠ flag on attestations from non-mainnet chains (mainnet = Ethereum 1, Scroll 534352)

File Digest (`useFileDigest`)

Users can pick files from local filesystem; the composable streams file content through @noble/hashes (SHA-256 or Keccak-256) with a size-estimated fake progress bar (~200 MB/s throughput model).

const { selectedFile, digestHex, fakeProgress, digestFile, digestFiles } = useFileDigest()
// Pick file → digestFile(file, 'KECCAK256') → digestHex.value = '0xabc...'
