Platform

01 / Problem

No unified mobile tool for multi-chain crypto investors

Crypto investors tracking assets across Ethereum, Bitcoin, BSC, Polygon, Arbitrum, and Base juggle multiple apps, browser tabs, and spreadsheets. Price data, wallet balances, and social signals live in disconnected silos — making timely, confident decisions difficult.

02 / Approach

Single native app, multiple on-chain data sources

Built natively in Swift/SwiftUI for performance and App Store compliance. Price data is streamed via Chainlink oracles and DexScreener's API, giving sub-second updates for thousands of tokens. Wallet portfolio analysis works by reading on-chain balances directly — no custodial login required.

A proprietary signal scoring model computes buy/hold/sell recommendations from price momentum, volume trends, and social sentiment indicators. The watchlist and 24h change UI are optimised for quick scanning, using SwiftUI's lazy rendering to stay smooth on large portfolios.

03 / Result

A unified dashboard across six chains

OnChain aggregates live market data, wallet portfolio value, and signal scores into a single native UI. Investors can monitor cross-chain positions, track 24h price changes, and act on signal alerts without leaving the app. Fully deployed to the App Store with privacy-first architecture — no server holds user keys.
