Firedancer is Jump Crypto's from-scratch Solana validator client written in C, designed for extreme performance and security with a restrictive sandbox architecture. It ships as two validators built from the same codebase: Frankendancer (a hybrid with Agave, available on testnet and mainnet-beta) and full Firedancer (still in development, no releases).

Use cases

• run a Solana validator node
• operate a high-performance Solana block producer
• improve Solana client diversity
• run a local Solana development cluster
• join Solana testnet with a custom validator
• reduce supply chain risk with an independent validator client

When to choose

• you operate a Solana validator and want better performance while leader
• you want to contribute to Solana client diversity and resilience
• you need a sandboxed validator with minimal system calls
• you want to run a local dev cluster for Solana testing

When to avoid

• you need a full from-scratch Firedancer validator in production (not yet released)
• you need a validator on non-Linux platforms (Linux kernel >= 4.18 required)
• you want a simple plug-and-play node without heavy hardware (256GB+ RAM recommended)
• you prefer a Rust-based validator like Agave
