+# Firedancer and Sig Implementation Review
+
+## Summary
+
+This document reviews the implementation of Firedancer and Sig (Solana Zig Validator) support in the OSVM CLI project. The implementation successfully adds these two alternative validator clients alongside the existing standard, Jito, and Agave options.
+
+## Changes Verified
+
+### 1. CLI Argument Parsing (`src/clparse.rs`)
+✅ **Status: Correctly Implemented**
+- Validator type options updated in all relevant locations (lines 462, 518)
+- New options: `["standard", "jito", "agave", "firedancer", "sig"]`
+- Default changed from "standard" to "agave" (lines 463, 519)
+
+### 2. Deployment Logic (`src/utils/ssh_deploy/deployments/solana.rs`)
+✅ **Status: Implemented with Good Approach**
+
+#### Firedancer Implementation (lines 175-195)
+- Installs build dependencies: `build-essential`, `cmake`, `pkg-config`, `libssl-dev`
+- Clones from official repository: `https://github.com/firedancer-io/firedancer.git`
+- Builds using `make -j` for parallel compilation
+- Installs to `/opt/firedancer/bin`
+- Creates compatibility symlinks:
+  - `fdctl` → `solana-validator`
+  - `fd_keygen` → `solana-keygen`
+
+#### Sig Implementation (lines 196-220)
+- Installs Zig compiler (v0.14.0-dev)
+- Clones from official repository: `https://github.com/syndica/sig.git`
+- Builds with optimization: `zig build -Doptimize=ReleaseFast`
+- Installs to `/opt/sig/bin`
+- Creates compatibility symlink: `sig` → `solana-validator`
+- Uses standard Solana keygen for compatibility
+
+### 3. Type Definitions (`src/utils/ssh_deploy/types.rs`)
+✅ **Status: Correctly Updated**
+- Comment on line 142 updated to include all supported types
+
+### 4. Documentation (`solana-validator-enhancements.md`)
+✅ **Status: Comprehensive**
+- Feature list updated to include both new validators
+- Example commands provided for each validator type
+- Clear explanations of the implementation approach
+
+### 5. Examples (`src/utils/examples.rs`)
+✅ **Status: Examples Added**
+- New example for Firedancer deployment (lines 158-160)
+- New example for Sig deployment (lines 164-166)
+
+## Potential Issues and Recommendations
+
+### 1. Build Time Considerations
+**Issue**: Building from source during deployment can be time-consuming
+- Firedancer and Sig are compiled from source during deployment
+- This can add significant time to the deployment process (10-30 minutes)
+
+**Recommendation**: Consider adding progress indicators or warning users about extended build times
+
+### 2. Version Management
+**Issue**: Both implementations use latest/master branches
+- No specific version pinning for Firedancer or Sig
+- Zig compiler version is hardcoded to 0.14.0-dev
+
+**Recommendation**: 
+- Add version parameters for Firedancer and Sig
+- Make Zig compiler version configurable for Sig builds
+
+### 3. Error Handling
+**Issue**: Build failures might leave incomplete installations
+- No cleanup if build fails midway
+- Dependencies might be installed even if build fails
+
+**Recommendation**: Add error handling to clean up partial installations
+
+### 4. Compatibility Layer
+**Strength**: Good use of symlinks for compatibility
+- Both validators can be managed using standard `solana-validator` commands
+- Maintains consistency with existing tooling
+
+### 5. Service Management
+**Issue**: The service uses hardcoded binary path
+- Line 341: `/home/$(whoami)/.local/share/solana/install/active_release/bin/solana-validator`
+- This path might not be correct for Firedancer/Sig which are installed to `/usr/local/bin/`
+
+**Recommendation**: Adjust service creation to use the appropriate binary path based on client type
+
+### 6. Disk Requirements
+**Issue**: No specific disk space validation for build requirements
+- Building from source requires significant temporary disk space
+- `/tmp` might not have enough space for large builds
+
+**Recommendation**: Add disk space checks before starting builds
+
+## Security Considerations
+
+1. **Build Dependencies**: Installing build tools increases attack surface
+2. **Source Verification**: No GPG signature or commit hash verification
+3. **Privilege Escalation**: Multiple `sudo` commands during installation
+
+## Performance Implications
+
+1. **Firedancer**: Known for high performance, should improve validator efficiency
+2. **Sig**: Written in Zig for performance, but still experimental
+3. **Build Optimization**: Both use release/optimized builds which is good
+
+## Testing Recommendations
+
+1. Test deployment on fresh systems
+2. Test deployment with limited disk space
+3. Test service start/stop/restart for both validators
+4. Verify hot-swap functionality works with new validators
+5. Test monitoring integration
+
+## Conclusion
+
+The implementation successfully adds Firedancer and Sig support to OSVM CLI. The approach using compatibility symlinks is clever and maintains backward compatibility. However, there are some areas for improvement, particularly around version management, error handling, and the service binary path issue that should be addressed.
+
+Overall, this is a solid implementation that extends OSVM CLI's capabilities to support cutting-edge Solana validator implementations.
