Jito Labs

Jito Labs is the Solana MEV infrastructure company behind Jito-Solana, the MEV-enabled validator client that runs on the majority of Solana mainnet stake, and the Jito Block Engine, an off-chain auction service that accepts bundles and transactions from searchers and forwards them to the next leader. Together with the Jito Foundation it stewards JitoSOL — Solana's largest MEV-aware liquid staking token — the StakeNet validator scoring system, the Jito Restaking and Vault programs that power Node Consensus Networks, the merkle-based token distributor used for airdrops, and the JTO governance token. Developer surfaces include a JSON-RPC API for bundle and transaction submission, a public REST tip floor and WebSocket tip stream for pricing, the ShredStream gRPC service for sub-slot Solana shreds, and the open mev-protos repository that defines the canonical Auth, Block Engine, Bundle, Packet, Relayer, Searcher, Shared, and ShredStream gRPC interfaces — with official SDKs in TypeScript, Python, Rust, and Go.

Use Cases

MEV Arbitrage

Searchers submit bundles capturing cross-AMM arbitrage opportunities on Solana DEXs.

Liquidation Bots

Lending protocol liquidations submitted as atomic bundles so a liquidation either lands fully or not at all.

Telegram Trading Bots

Consumer trading bots use ShredStream and sendBundle for low-latency token sniping.

High-Frequency Trading

Market makers consume ShredStream for the lowest-latency view of block state and use sendTransaction with bundleOnly for priority routing.

NFT Mint Sniping

Bundles guarantee atomic mint + transfer flows that revert cleanly if the mint slot is missed.

Liquid Staking

Users hold JitoSOL to earn staking and MEV rewards while keeping liquidity for DeFi.

Restaked Security

New NCN workloads (oracles, bridges, DA, coprocessors) bootstrap economic security by renting restaked SPL collateral from Jito Vaults.

Validator Operations

Solana validators run Jito-Solana plus jito-relayer to participate in the bundle auction and capture MEV rewards.
