Intent-based Web3 wallet for X402
The problem Intent Wallet solves
Most Web3 applications today still rely on low-level transaction signing, confusing wallet popups, and complex flows that overwhelm users. Developers who want to build intent-based or abstracted experiences struggle with:
-
Setting up a clean backend structure
-
Handling signatures, verification, or webhook-style flows
-
Managing API routes, logging, raw request capture
-
Quickly iterating on a frontend + backend together
-
Deploying a production-ready server without friction
IntentWallet solves this by providing a minimal, modular, and scalable boilerplate for intent-driven applications.
It offers an Express + TypeScript backend with automatic logging, raw body capture, JSON introspection, Vite-powered frontend development, and seamless Railway deployment.
This allows developers to focus on building intent logic instead of fighting framework setup.
With IntentWallet, building modern intent-based dApps or payment flows becomes much faster, cleaner, and more reliable.
Challenges I ran into
Raw Body Parsing for Verification
Handling raw request bodies (for signature verification or webhook flows) conflicted with Express’ JSON middleware.
I solved this by creating a custom middleware that captures raw data before parsing.
Shared Server Instance for WebSocket Upgrades
I needed both Express routes and potential WebSocket upgrades from a single server instance.
The fix was exporting the server reference and restructuring the initialization logic.
Vite + Express Integration
Running a full-stack dev environment with hot reload on both backend and frontend was tricky.
I solved it by conditionally enabling Vite in development and static serving in production.
Railway Deployment Port Issues
Railway assigns dynamic ports, which initially caused binding failures.
This was fixed by using process.env.PORT and binding to 0.0.0.0.
Maintaining Clean Route Structure
Express projects often get messy as they grow.
I designed a registerRoutes loader that automatically registers modular routes.
These challenges helped me build a cleaner, scalable foundation for future intent-based applications.
