Acc.IRumour — Web3 social trading on Hyperliquid

AltLayer wanted a Web3 social trading product where market rumours become tradable positions — a pixel/Minecraft-styled app with strict design direction that had to ship across three distribution shells (PWA, Farcaster Miniapp, LINE DappPortal Mini Dapp) from one codebase, with wallet-signing flows, perpetual trading, bridging, and a live social layer.

• Led the frontend through several iterations to production launch — implemented the pixel/Minecraft-style UI with strict design direction: button shadow effects, pixel-grid layouts, responsive design across breakpoints.
• Owned the Farcaster Miniapp shell end-to-end — SDK integration, environment-specific manifest handling, Farcaster OAuth in linked accounts, and miniapp-aware navigation.
• Built the LINE DappPortal Mini Dapp integration on the LINE DappPortal SDK, with testing components and a quick-start handover for the team.
• Shipped the wallet-setup and auth-routing flow on Privy embedded wallets — account switching, user-info-aware routing, transaction error handling, and a debug surface for cross-shell verification.
• Built the perps trading UI against the Hyperliquid SDK — long / short flows, leverage and amount sliders, and consistent navigation state across trading routes — plus the smart-contract bridging behind the funding path.
• Integrated OKX and LI.FI bridging on the frontend so users could choose between bridge providers when funding positions.
• Integrated Rumour Viber on Tencent Cloud Chat and led a coordinated mobile chat-layout overhaul across the messaging surface.
• Built internal admin tooling for reviewing and creating rumours; supported agent/bot-triggered workflows that scan X/Twitter trends and create rumours from discovered signal.
• Wired the PWA update-dialog and service-worker flow, added Arbitrum Sepolia support for pre-prod verification, and authored regression-testing documentation for the team.
• Wrote Playwright E2E tests in a separate testing repository, using Synpress where MetaMask wallet-signing flows were involved.

• Shipped to production at rumour.app as a live AltLayer product across all three shells.
• One codebase, three distribution surfaces — PWA, Farcaster Miniapp, LINE DappPortal — with wallet-signing parity across all of them.
• Rumour-to-trade flow live end-to-end: chatroom signal → Hyperliquid long/short perp position without leaving the app.
• Playwright + Synpress E2E coverage over the MetaMask wallet-signing flows, maintained in a dedicated testing repository.
