Jito FireBAM: BAM live on Frankendancer in testnet

Jito has released FireBAM: the BAM privacy stack now runs on Frankendancer validators (~12 percent mainnet stake). Audit by Asymmetric Research until end of June 2026, mainnet release in July.

What happened

Jito announced FireBAM — an extension of the BAM stack (Block Assembly Marketplace) to Frankendancer validators. Testnet and mainnet early access have been live since 13 May 2026. Official announcement on the BAM blog plus Jito thread on X.

What BAM does technically

BAM is Jito’s privacy and determinism layer for Solana block construction. Three technical core points:

  • TEE integration: transactions are processed in Trusted Execution Environments. They remain encrypted until execution — front-running by validators is cryptographically prevented.
  • Decentralised scheduling: block construction is split between high-performance BAM nodes (schedulers) and validators. Programmable plugins allow custom sequencing logic.
  • Deterministic execution with attestations: BAM cryptographically signs the order of included transactions. Users can verify after the fact whether their transaction was ordered fairly.

Before FireBAM, BAM only ran on Jito’s own Solana client (a fork of the Agave validator).

What changes with FireBAM

FireBAM brings BAM to Frankendancer — Anza’s and Jump Trading’s hybrid validator client (see our explainer: Firedancer and Frankendancer).

  • Stake coverage: Frankendancer currently holds roughly 12 percent of mainnet stake. With FireBAM, these validators can become BAM-compatible without switching back to Agave.
  • Firedancer (pure-C client) follows later: BAM is also planned for integration after Firedancer mainnet full release. Frankendancer is the first step.
  • Privacy-performance bridge: FireBAM combines Frankendancer performance (Jump-optimised networking layer) with BAM privacy and determinism guarantees.

Audit + roadmap

  • Audit provider: Asymmetric Research
  • Audit period: until end of June 2026 (final fixes)
  • Mainnet release expectation: July 2026
  • Open-source release: planned after mainnet release

Context

Solana’s client-diversity goal requires that no single validator client holds more than one-third of stake. Frankendancer growth to 12 percent is a step in this direction. FireBAM extends the privacy and fairness profile of this second client layer — relevant for DeFi applications that need MEV protection, and for wallet software expecting verifiable transaction ordering.

Not financial advice. This article describes technical validator infrastructure. Early adoption phases carry elevated software risk until audit completion.
