Rumour — Web3 social trading on Hyperliquid

Impact

Led frontend across the rumour-to-trade flow — owned the Farcaster Miniapp and LINE DappPortal shells end-to-end, the wallet-setup flow on Privy embedded wallets, the Rumour Viber chat experience on Tencent Chat, and the perps trading UI on the Hyperliquid SDK.

Outcomes

• 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.
• Integrated Rumour Viber on Tencent Cloud Chat and led a coordinated mobile chat-layout overhaul across the messaging surface.
• Built the perps trading UI against the Hyperliquid SDK — long / short flows, leverage and amount sliders, and consistent navigation state across trading routes.
• 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.
