**APIs profiled:** 10

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 (8)

- **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.

- **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.
