🏗️ Architecture

Sonr consists of three primary components and three custom modules:

Service Architecture

┌─────────┐     ┌─────────┐     ┌─────────┐
│  Caddy  │────▶│  snrd   │     │  IPFS   │
└─────────┘     └─────────┘     └─────────┘

     └─────────▶│ Highway │────▶│  Redis  │
                └─────────┘     └─────────┘

• Caddy: Reverse proxy with gRPC-Web support (port 80)
• Redis: Task queue backend for Highway (port 6379)
• Highway: UCAN-based task processor (port 8090)
• IPFS: Distributed storage (API: 5001, Gateway: 8080)
• snrd: Blockchain node (gRPC: 9090, REST: 1317)

Cross-Platform Support

The localnet target now automatically detects and uses the best available method:

1. Checks for local binary (built with make install)
2. Falls back to Docker if available
3. Handles permission issues on systems like Arch Linux
4. Supports systemd service installation (see etc/systemd/)

Core Components

1. Blockchain Node (snrd)

The main blockchain daemon built with Cosmos SDK v0.50.14, providing:

• AutoCLI for command generation
• EVM compatibility via Evmos integration
• IBC for cross-chain communication
• CosmWasm smart contract support

2. Highway Service (hway)

An Asynq-based task processing service for vault operations:

• Redis-backed job queue with priority levels
• Actor-based concurrency using Proto.Actor framework
• Processes cryptographic operations through WebAssembly enclaves

3. Motor Plugin (motr)

WebAssembly-based vault system providing:

• Secure execution environment for sensitive operations
• Hardware-backed key management
• Multi-party computation capabilities

🔧 Configuration

Environment Variables

Environment variables can be configured via Docker Compose:

# Chain configuration
export CHAIN_ID="localchain_9000-1"
export BLOCK_TIME="1000ms"

# Network selection for Starship
export NETWORK="devnet"  # or "testnet"

# Redis configuration
REDIS_URL=redis://redis:6379
REDIS_DB=0

# Highway service
HIGHWAY_PORT=8090
LOG_LEVEL=debug

# IPFS configuration
IPFS_API_URL=http://ipfs:5001

# Caddy configuration
CADDY_DOMAIN=localhost

Environment variables can be set directly or via a .env file in the project root.

Docker Compose Services

The project includes a comprehensive Docker Compose setup for running all backend services:

# Start all services (Redis, Highway, Caddy, IPFS)
make docker-up

# Stop all services
make docker-down

# View service logs
make docker-logs           # All services
make docker-logs-redis     # Specific service

# Check service health
make docker-status

# Clean up Docker resources
make docker-clean

Starship Configuration

Edit starship.yml to configure multi-node testnets:

chains:
  - id: sonrtest_1-1
    name: custom
    numValidators: 3
    image: onsonr/snrd:latest
    # ... additional configuration

Troubleshooting

Services not starting:

# Check service status
make docker-status

# View detailed logs
make docker-logs

# Ensure Docker network exists
docker network ls | grep sonr-network

Redis connection issues:

# Test Redis connectivity
docker exec redis redis-cli ping

# Check Redis logs
make docker-logs-redis

IPFS not accessible:

# Verify IPFS is running
curl http://127.0.0.1:5001/api/v0/version

# Check IPFS logs
docker compose -f etc/stack/compose.yml logs ipfs

Port conflicts:

• Caddy: 80 (HTTP)
• Redis: 6379
• Highway: 8090
• IPFS API: 5001
• IPFS Gateway: 8080

Stop conflicting services or modify ports in etc/stack/compose.yml.

🏗️ Project Structure

Versioning & Publishing

The monorepo uses Changesets for package versioning:

# Add a changeset for your changes
pnpm changeset

# Version packages based on changesets
pnpm changeset version

# Publish packages to npm
pnpm changeset publish

Key Technologies

• pnpm workspaces: Efficient dependency management with single lockfile
