Amplifi
Bitcoin-backed DeFi. Borrow, earn, and swap — on Starknet.
Overview
Amplifi is a DeFi platform that brings Bitcoin holders into the Starknet ecosystem. We designed and engineered the complete product — a web app where users can borrow against their BTC, earn yield through curated staking pools across multiple protocols, and swap assets cross-chain in seconds. Built with a clean, institutional aesthetic and social wallet onboarding so anyone can get started without the usual Web3 friction.
blockchains bridged — Bitcoin and Starknet in one interface
of the DeFi stack — designed and engineered by TCC
DeFi on emerging L2s is powerful on paper but brutal in practice — fragmented flows, wallet setup barriers, and interfaces built for insiders. The client needed a platform with the depth of institutional tooling and the clarity of a consumer product, all while bridging two completely separate blockchains.
We built the complete Amplifi product across four modules: a BTC-backed borrowing flow with live loan health tracking, an earn page surfacing the best yield opportunities across staking protocols, a cross-chain atomic swap, and a full order history with on-chain verification. We layered in social-login wallet onboarding via Privy to remove the biggest drop-off point in Web3 — and tied it all together with a design system rooted in Amplifi's deep green brand identity.
Closing thoughts
Amplifi launched as a complete DeFi suite — not a feature, not an MVP, but a full platform. From the first wallet connect to a live cross-chain swap, every screen was designed and built by TCC to make Bitcoin-backed DeFi on Starknet feel effortless.
