+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+Nym is a privacy platform that uses mixnet technology to protect against metadata surveillance. The platform consists of several key components:
+- Mixnet nodes (mixnodes) for packet mixing
+- Gateways (entry/exit points for the network)
+- Clients for interacting with the network
+- Network monitoring tools
+- Validators for network consensus
+- Various service providers and integrations
+

+
+## Architecture
+
+The Nym platform consists of various components organized as a monorepo:
+
+1. **Core Mixnet Infrastructure**:
+   - `nym-node`: Core binary supporting mixnode and gateway modes
+   - `common/nymsphinx`: Implementation of the Sphinx packet format
+   - `common/topology`: Network topology management
+   - `common/types`: Shared data types across components
+
+2. **Network Monitoring**:
+   - `nym-network-monitor`: Monitors the network's reliability and performance
+   - `nym-api`: API server for network stats and monitoring data
+   - Metrics tracking for nodes, routes, and overall network health
+
+3. **Client Implementations**:
+   - `clients/native`: Native Rust client implementation
+   - `clients/socks5`: SOCKS5 proxy client for standard applications
+   - `wasm`: WebAssembly client implementations (for browsers)
+   - `nym-connect`: Desktop and mobile clients
+
+4. **Blockchain & Smart Contracts**:
+   - `common/cosmwasm-smart-contracts`: Smart contract implementations
+   - `contracts`: CosmWasm contracts for the Nym network
+   - `common/ledger`: Blockchain integration
+
+5. **Utilities & Tools**:
+   - `tools`: Various CLI tools and utilities
+   - `sdk`: SDKs for different languages and platforms
+   - `documentation`: Documentation generation and management
+
+## Packet System
+
+Nym uses a modified Sphinx packet format for its mixnet:
+
+1. **Message Chunking**:
+   - Messages are divided into "sets" and "fragments"
+   - Each fragment fits in a single Sphinx packet
+   - The `common/nymsphinx/chunking` module handles message fragmentation
+
+2. **Routing**:
+   - Packets traverse through 3 layers of mixnodes
+   - Routing information is encrypted in layers (onion routing)
+   - The final gateway receives and processes the messages
+
+3. **Monitoring**:
+   - Monitoring system tracks packet delivery through the network
+   - Routes are analyzed for reliability statistics
+   - Node performance metrics are collected
+
+## Network Protocol
+
+Nym implements the Loopix mixnet design with several key privacy features:
+
+1. **Continuous-time Mixing**:
+   - Each mixnode delays messages independently with an exponential distribution
+   - This creates random reordering of packets, destroying timing correlations
+   - Offers better anonymity properties than batch mixing approaches
+
+2. **Cover Traffic**:
+   - Clients and nodes generate dummy "loop" packets that circulate through the network
+   - These packets are indistinguishable from real traffic
+   - Creates a baseline level of traffic that hides actual communication patterns
+   - Provides unobservability (hiding when and how much real traffic is being sent)
+
+3. **Stratified Network Architecture**:
+   - Traffic flows through Entry Gateway → 3 Mixnode Layers → Exit Gateway
+   - Path selection is independent per-message (unlike Tor)
+   - Each node connects only to adjacent layers
+
+4. **Anonymous Replies**:
+   - Single-Use Reply Blocks (SURBs) allow receiving messages without revealing identity
+   - Enables bidirectional communication while maintaining privacy
+
+## Network Monitoring Architecture
+
+The network monitoring system is a core component that measures mixnet reliability:
+
+1. The `nym-network-monitor` sends test packets through the network
+2. These packets follow predefined routes through multiple mixnodes
+3. Metrics are collected about:
+   - Successful and failed packet deliveries
+   - Node reliability (percentage of successful packet handling)
+   - Route reliability (which specific route combinations work best)
+4. Results are stored in the database and used by `nym-api` to:
+   - Present node performance statistics
+   - Determine network rewards
+   - Provide route selection guidance to clients
+
+In the current branch, metrics collection is being enhanced with a fanout approach to submit to multiple API endpoints.

+
+## CI/CD Pipeline
+
+The project uses GitHub Actions for CI/CD with several key workflows:
+
+1. **Build and Test**:
+   - `ci-build.yml`: Main build workflow for Rust components
+   - Tests are run on multiple platforms (Linux, Windows, macOS)

+
+2. **Release Process**:
+   - Binary artifacts are published on release tags
+   - Multiple platform builds are created
+
+3. **Documentation**:
+   - Documentation is automatically built and deployed
+
+## Database Structure
+
+The system uses SQLite databases with tables like:
+- `mixnode_status`: Status information about mixnodes
+- `gateway_status`: Status information about gateways
+- `routes`: Route performance information (success/failure of specific paths)
+- `monitor_run`: Information about monitoring test runs
+
+## Development Workflows
+
+### Running a Node
+
+To run the mixnode or gateway:
+
+```bash
+# Run nym-node as a mixnode with specified identity
+cargo run -p nym-node -- run --mode mixnode --id my-mixnode
+
+# Run nym-node as a gateway
+cargo run -p nym-node -- run --mode gateway --id my-gateway
+```
+
+### Configuration

+Nodes can be configured with files in various locations:
+- Command-line arguments
+- Environment variables
+- `.env` files specified with `--config-env-file`
+
+### Monitoring

+
+## Deployment and Advanced Configurations
+
+### Deployment Structure
+
+The `deployment/` directory contains Ansible playbooks and configurations for various deployment scenarios:
+
+- **`aws/`**: AWS-specific deployment configurations
+- **`mixnode/`**: Mixnode deployment playbooks
+- **`gateway/`**: Gateway deployment playbooks
+- **`validator/`**: Validator node deployment
+- **`sandbox-v2/`**: Complete sandbox environment setup
+- **`big-dipper-2/`**: Block explorer deployment
+
+### Sandbox V2 Deployment
+
+The sandbox-v2 deployment (`deployment/sandbox-v2/`) provides a complete test environment:
+
+```bash
+# Key playbooks:
+- deploy.yaml              # Main deployment orchestrator
+- deploy-mixnodes.yaml    # Deploy mixnodes
+- deploy-gateways.yaml    # Deploy gateways
+- deploy-validators.yaml  # Deploy validator nodes
+- deploy-nym-api.yaml     # Deploy API services
+```
+
+### Custom Environment Setup
+
+To create a custom environment:
+
+1. Copy an existing env file: `cp envs/sandbox.env envs/custom.env`
+2. Modify the network endpoints and contract addresses
+3. Update the `NETWORK_NAME` to your identifier
+4. Set appropriate mnemonics and keys (use fresh ones for production!)
+
+### Contract Addresses
+
+Contract addresses are network-specific and defined in environment files:
+- Mixnet contract: Manages mixnode/gateway registry
+- Vesting contract: Handles token vesting schedules
+- Coconut contracts: Privacy-preserving credentials
+- Name service: Human-readable address mapping
+- Ecash contract: Electronic cash functionality
+
+### Local Network Setup
+
+For a completely local network:
+```bash
+# Start local chain
+./scripts/localnet_start.sh
+
+# Deploy contracts
+cd contracts
+make deploy-local
+
+# Start nodes with local config
+dotenv -f envs/local.env -- cargo run -p nym-node -- run --mode mixnode
+```
+
+## Common Issues and Troubleshooting
+
+### Database Issues
+
+- When modifying database queries, you must update SQLx query caches:
+  ```bash
+  cargo sqlx prepare
+  ```
+- If you see SQLx errors about missing query files, this is likely the cause
+- For "database is locked" errors with SQLite, ensure only one process accesses the DB
+- For PostgreSQL connection issues, verify DATABASE_URL and that the server is running
+
+### API Connection Issues
+
+- Check the environment variables pointing to the APIs (NYM_API, NYXD)
+- Verify network connectivity and API health endpoints
+- For authentication issues, check node keys and credentials
+- Common endpoints to verify:
+  - API health: `$NYM_API/health`
+  - Chain status: `$NYXD/status`
+  - Contract info: `$NYXD/cosmwasm/wasm/v1/contract/$CONTRACT_ADDRESS`
+
+### Build Problems
+
+- Clean dependencies with `cargo clean` for a fresh build
+- Check for compatible Rust version (1.80+ recommended)
+- For smart contract builds, ensure wasm-opt is installed: `npm install -g wasm-opt`
+- For cross-compilation issues, check target-specific dependencies
+- WASM build issues: Ensure wasm32-unknown-unknown target is installed:
+  ```bash
+  rustup target add wasm32-unknown-unknown
+  ```
+- For "cannot find -lpq" errors, install PostgreSQL development files:
+  ```bash
+  # Ubuntu/Debian
+  sudo apt-get install libpq-dev
+  # macOS
+  brew install postgresql
+  ```
+
+### Environment Issues
+
+- Contract address mismatches: Ensure you're using the correct environment file
+- "Account sequence mismatch": The account nonce is out of sync, wait and retry
+- Token decimal issues: Sandbox uses different decimal places than mainnet
+- API version mismatches: Ensure your local API version matches the network
+- "Insufficient funds": Get test tokens from faucet (sandbox) or check balance
+- Gateway/mixnode bonding issues: Verify minimum stake requirements
+
+## Working with Routes and Monitoring
+
+1. Route monitoring metrics are stored in a `routes` table with:
+   - Layer node IDs (layer1, layer2, layer3, gw)
+   - Success flag (boolean)
+   - Timestamp
+
+2. To analyze routes:
+   - Check `NetworkAccount` and `AccountingRoute` in `nym-network-monitor/src/accounting.rs`
+   - View monitoring logic in `common/nymsphinx/chunking/monitoring.rs`
+   - Observe how routes are submitted to the database in the `submit_accounting_routes_to_db` function
+
+## Performance Optimization
+
+### Profiling and Benchmarking
+
+```bash
+# Run benchmarks
+cargo bench -p nym-node
+
+# Profile with perf (Linux)
+cargo build --release --features profiling
+perf record --call-graph=dwarf ./target/release/nym-node run --mode mixnode
+perf report
+
+# Generate flamegraph
+cargo install flamegraph
+cargo flamegraph --bin nym-node -- run --mode mixnode
+```
+
+### Common Performance Considerations
+
+- Use bounded channels for backpressure
+- Batch database operations where possible
+- Monitor memory usage with `RUST_LOG=nym_node::metrics=debug`
+- Use connection pooling for database connections
+- Consider using `jemalloc` for better memory allocation performance
