Shipping a Multi-Chain Frontend Without Rewriting Every Screen

Overview

A product built assumption-by-assumption for one chain tends to have chain-specific logic scattered across every screen. Extending it to a second or third chain usually means touching all of it — unless the data layer is shaped to prevent that from the start.

The Problem

Every screen had its own idea of what a "vault" or "strategy" looked like, with chain-specific fields baked directly into components. Adding a new chain meant hunting down every place that assumption lived.

The Approach

The fix was a single typed data layer for vault and strategy state, shared across chains, plus server-driven configuration for strategy cards so new strategies could ship without new UI code. Shared UI components stopped each screen from re-solving the same table and form patterns independently.

Key Takeaways

Rebuilding from the data layer up — instead of screen by screen — is what let the UI stay consistent across chains. A shared component library paid for itself within a single release cycle.
