RampX - Crypto Onboarding & Trading dApp
Multi-chain DeFi dApp I delivered end to end, with a fiat on and off ramp, DEX aggregator, perpetuals, lending, social vaults, and an embedded wallet across Ethereum, Solana, and Base.
Outcome
Multi-chain DeFi app built end-to-end
I delivered the full DeFi product stack across web, mobile, wallet, and trading. The cross-chain swap and perpetuals app reached production-ready completion but was held back from public launch.
Overview
Most retail crypto products force users to bounce between separate apps for fiat onboarding, swaps, perpetuals, lending, and self-custody, and each context switch is a moment where users drop off. RampX consolidated those workflows into a single multi-chain dApp covering Ethereum, Solana, Base, and additional networks, with a ZK-powered fiat on and off ramp, a DEX aggregator, a perpetuals platform, lending integration, social trading vaults, an embedded wallet, and a crypto debit card. I delivered the stack across web, mobile, wallet, and trading layers over several product iterations, including native Android and iOS builds and an account abstraction layer using ZeroDev, Dynamic Labs, Biconomy, Privy, and wagmi. The cross-chain swap and perpetuals app reached completion but was never publicly launched. Visitors can still see the heavily animated original landing page through the demo link.
What it does
- Users complete fiat on and off ramping with ZK-based privacy protection.
- A DEX aggregator scans multiple exchanges for the best swap rates and supports gasless cross-chain trades.
- The platform supports perpetuals trading and lending alongside spot swaps, so users do not need separate apps for advanced strategies.
- Social trading vaults let users follow expert traders and mirror their positions automatically.
- An embedded wallet handles send, receive, portfolio tracking, and transaction history with account abstraction across ZeroDev, Dynamic Labs, Biconomy, and Privy.
- Live price feeds from Codex and CoinGecko drive scrolling token tickers and real-time valuations throughout the interface.
- Native Android and iOS apps, built with Capacitor, deliver the same trading and wallet capabilities as the web app.
