Stellar Smart Wallet Demo

This monorepo provides a complete, modular demo application for a Stellar-based smart wallet. It includes everything you need to explore and extend a full-stack Stellar wallet solution. From backend services and frontend interface to smart contracts. While not a white-label solution, it serves as a solid foundation for developers who want to build their own Stellar-powered wallets.

Monorepo Structure

This repository is organized as follows:

• apps/
  • backend/ | Node.js backend (API)
  • web/ | React-based web application
• contracts/ | Smart contracts (e.g., Soroban)
• scripts/ | Utility scripts for setting up and managing the environment
• Makefile | Project-level build and dev commands
• docker-compose.yml | Container orchestration

Requirements

• Docker
• Node.js v22+
• NPM
• Make

Quick Start

To get started with the full environment locally using Docker:

make docker-setup-dev
make docker-start-dev

Environment Variables

Make sure to configure your environment variables before running the apps:

• Backend

  • apps/backend/src/config/.env.example (used as a reference)
  • apps/backend/src/config/.env.development
  • apps/backend/src/config/.env.test

• Web

  • apps/web/src/config/.env.example (used as a reference)
  • apps/web/src/config/.env.local
  • apps/web/src/config/.env.test

Running Apps Individually

You can also work on a specific app (e.g., backend or web) without running the full stack.

Example: Running the Backend Only

make docker-setup-dev PROFILE=backend
make docker-start-dev PROFILE=backend

Example: Running the Web App Only

make docker-setup-dev PROFILE=web
make docker-start-dev PROFILE=web

Local Development Commands

All workspace apps support the following make commands:

Command	Description
setup-dev	Installs dependencies and performs initial setup for the app
clean-setup-dev	Removes previous builds and sets up a clean dev environment
clean-setup	Cleans previous installations and prepares for new setup
build	Builds the selected app
start	Starts the app in production mode
start-dev	Starts the app in development mode
start-staging	Starts the app using staging configuration
test	Runs tests for the selected app
test-coverage	Runs tests and shows coverage
lint	Runs ESLint on the codebase
lint-fix	Auto-fixes linting issues
type-check	Runs TypeScript type checking
format-code	Formats the code using Prettier
serve	Runs a local static server (only for web)
migration-run	Runs database migrations (only for backend)
migration-generate	Generates a new migration based on entities changes (only for backend)
docker-run-migration-run	Runs database migrations - on a Docker container (only for backend)
docker-run-migration-generate	Generates a new migration based on entities changes - on a Docker container (only for backend)

Use these commands by specifying the APP variable. For example:

make build APP=web
make test APP=backend

Smart Contracts

The contracts folder contains Stellar smart contracts (e.g., Soroban) used by the backend or client apps. Instructions for compiling, testing, and deploying contracts are documented in that directory’s README.

Proofs API

The backend includes a proofs API for Merkle proof verification and airdrop claims. The airdrop contract needs to be deployed and proofs need to be uploaded to the backend before users can claim their airdrops.

Setup

1. Deploy an airdrop contract (see contracts/)
2. Generate proofs: npm run --workspace=scripts generate-proofs
3. Upload proofs: npm run --workspace=scripts upload-proofs
4. Query proofs: GET /api/proofs/{address}
