Jito BAM Preconfirmations Go Live, Creating New Revenue Stream for Solana Validators
Jito’s BAM preconfirmations launched with coverage spanning more than 34% of Solana’s network stake, introducing a revenue split for validators, distribution partners, and the Jito DAO.
Jito has launched BAM preconfirmations, creating a new revenue layer for Solana validators that stream committed transaction data to traders and applications. The service went live on September 9 and already covers more than 34% of Solana’s total network stake through launch partnerships with Helius and Triton.
A New Revenue Layer for Validators
BAM preconfirmations are designed for users that value low-latency transaction data, including market makers, arbitrageurs, and liquidation bots. By receiving committed transaction information more quickly, these participants can update quotes, identify price discrepancies, and act on liquidations with greater precision.
The revenue generated by the service is divided among three groups:
- 30% goes to distribution partners such as Helius and Triton.
- 35% goes to BAM validators, distributed proportionally according to stake weight through priority fees.
- 35% flows to the Jito DAO treasury.
Participating validators can run either the AgaveBAM or FireBAM clients. Validators that do not want to participate can currently opt out through Discord, while a self-service toggle is planned for a future release. Actual revenue generation for validators is expected to begin in October 2026.
How BAM Handles Transaction Sequencing
BAM is not a new system. It reached early mainnet around September 25, 2025, and hundreds of validators adopted compatible clients in the months that followed. That installed base helped provide the foundation for the preconfirmation launch.
The architecture uses Trusted Execution Environments, or TEEs, specialized hardware enclaves that process data in isolation. Within BAM, TEEs enforce privacy requirements during transaction sequencing. This separates transaction ordering handled by BAM nodes from the execution work performed by validators, creating a clearer division of labor in Solana’s block-building process.
Jito says routing sequencing through TEE-protected BAM nodes can reduce opportunities for harmful maximal extractable value, or MEV, while allowing validators to monetize the legitimate value of their network position. Preconfirmations extend that model by turning the speed of committed transaction data into a source of revenue.
What This Means
The launch gives participating validators an additional income opportunity without requiring new hardware, although the returns will initially favor operators with larger stake positions in absolute terms. Since distributions are stake-weighted, the percentage return is expected to be broadly similar across participants.
For Solana, the rollout also deepens the role of specialized infrastructure in transaction markets. More than one-third of network stake is already covered, but the system’s long-term impact will depend on validator participation, demand from trading applications, and whether faster data delivery produces sustainable fees without introducing new centralization or sequencing risks.
