How Does Jito Work?

JitoSOL is a reward-bearing LST that accrues staking rewards plus MEV tips, increasing in value relative to SOL over time

JitoSOL's MEV-enhanced yield (1-3% above base staking) differentiates it from standard LSTs. However, MEV yield is variable and depends on transaction flow and validator behavior.

MEV tips from bundle auctions are pooled and distributed to JitoSOL holders, adding 1-3% yield on top of base 6-8% staking rewards

MEV redistribution to stakers is a novel value capture mechanism on Solana. However, it creates incentives for validators to maximize MEV extraction, including harmful strategies like sandwich attacks.

BAM (Block Assembly Marketplace) decentralizes block building via TEE nodes with customizable plugins for transaction sequencing

BAM launched July 2025 to reduce exploitative MEV. Routes transactions through TEEs for privacy, but TEE dependency introduces hardware trust assumptions and potential side-channel attack vectors.

Jito Block Engine enables searchers to submit transaction bundles for atomic execution, with tips flowing to validators and stakers

Block Engine is used by majority of Solana's stake-weighted validators. Dominant market position creates centralization risk — Jito infrastructure becomes a critical dependency for Solana block production.

SOL staked via Jito is delegated across a curated set of validators running Jito-Solana client software

Validator curation ensures MEV capture but creates a permissioned set. Banned validators (15+ in 2025) demonstrate ongoing enforcement challenges.

JTO governance token with DAO treasury receiving 100% of Block Engine and BAM fees (~$15M/year) per JIP-24

JIP-24 (August 2025) redirected all fee revenue to DAO treasury. Concentrates significant revenue in governance-controlled treasury, creating governance attack incentives.

Revenue split between MEV tips (to stakers via JitoSOL), Block Engine fees (to DAO treasury), and validator commissions

Three-way revenue split across stakers, DAO, and validators creates complex economic incentives.

Modified Solana validator client used by majority of stake-weighted validators to capture and route MEV

Jito-Solana client is infrastructure-level software. Bugs or vulnerabilities in this client could affect the majority of Solana validators simultaneously.

The MEV redistribution model incentivizes validators to maximize extractable value, including harmful sandwich attacks.

BAM's TEE dependency introduces hardware trust assumptions. A TEE vulnerability or side-channel attack could compromise transaction privacy guarantees.

JitoSOL is widely used as collateral across Solana DeFi. During market stress, JitoSOL can trade at a discount to SOL, triggering cascade liquidations across lending protocols.

JIP-24 directs ~$15M/year in Block Engine and BAM revenue to the DAO treasury. This concentrated revenue creates governance capture incentives.

Majority of Solana validators run Jito-Solana client. A critical bug in this client would create correlated downtime risk across the majority of Solana's stake-weighted validators.
