Hash Chat – Crypto Messaging App

#Chat – Crypto Messaging App

Slack-style communication enhanced with a social feed and a crypto layer. I designed the end-to-end desktop and mobile experience, unifying chats, channels, Top posts, wallet, and P2P transfers into one clean, dark-themed UI.

Goals

Deliver a fast, familiar chat experience across desktop and mobile, integrating wallet and P2P transfers without breaking the conversation flow. Ship a time‑boxed MVP from scratch, covering the core flows—messages, channels, social feed, and wallet send/request/confirm—with production‑ready UI. Establish a lean component library that covers only missing and high‑leverage patterns to accelerate delivery and ensure visual and behavioral consistency, rather than building a full‑scale design system. Align design decisions to business outcomes by reducing time‑to‑first transfer and increasing wallet activation while upholding accessibility and a robust dark theme. Desktop‑first delivery with mobile parity for key wallet and P2P actions.

Money Meets Chat (Desktop)

Talk, send, post — all in one screen, no detours or dead endsimage.jpg
One tap from message to Pay/Request; receipt lands back in the threadimage.jpg
Curated Top Posts keep the room alive while the chat flowsimage.jpg
Draft once, share anywhere: compose on the right, drop into chat or feedimage.jpg
Feels fast and familiar, but quietly reduces time to first transfer

Channel + Wallet Sidecar (Desktop)

Follow the channel while the wallet stays docked on the right
One‑tap Pay/Request from composer; balance, QR, and tokens are always visible
Rank and progress ring gamify activation; “Renew now” card prompts subscription
Token list with fiat equivalents enables quick switching and confidence
Outcome: chat focus intact, faster send/request, higher wallet engagement

Channels Hub (Desktop)

Channel‑first layout: feeds and servers on the left, thread in focus center
Quick subscribe/manage lists with section dividers and add‑channel FAB
Inline subscription card in chat (10 USDC/month) with “Renew now” CTA
Right rail hidden; “Top posts” tab appears as a grabber for later
Outcome: stay in channel, act on subs without leaving the conversation

Conversation + Wallet Dock (Desktop)

Chat stays center; wallet is pinned right with Request/Send always reachable
QR in‑thread for quick scan payments; composer offers one‑tap Pay
Token/NFT tabs and balances visible to reduce uncertainty before actions
Left rail groups feeds, utilities, servers; unread pills drive navigation
Outcome: payments happen mid‑chat, with full balance context and fewer hops

Mobile Core Flow

Chat: fast replies with inline actions; clean canvas keeps focus on the thread.
Feed: rich cards with Follow/Like/Comment; one bottom nav builds muscle memory.
Wallet: profile and rank nudges activation with a clear Deposit prompt.
Balance: Request/Send always visible; QR toggle enables instant scan-to-pay.
Result: from message to transfer in one flow—no context switching.

Thanks for watching!
