Jito Labs (jito)

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.

APIs

Jito Block Engine JSON-RPC API

JSON-RPC API for submitting atomic bundles of up to five Solana transactions to the Jito Block Engine via sendBundle, plus getBundleStatuses, getInflightBundleStatuses, getTipAccounts, getRandomTipAccount, and a sendTransaction proxy. Endpoints are exposed from regional Block Engine clusters in Amsterdam, Dublin, Frankfurt, London, New York, Salt Lake City, Singapore, Tokyo, and global mainnet and testnet front-doors.

Jito Bundles Tip Floor API

Public REST endpoint exposing the recent tip floor — landed-tips percentiles (25th/50th/75th/95th/99th plus EMA50) — used by searchers to size the SOL tip on sendBundle. Pairs with the tip_stream WebSocket for continuous updates.

Jito Relayer gRPC

Relayer gRPC service that sits in front of a Jito-Solana validator, exposing GetTpuConfigs and SubscribePackets so the validator can receive deduplicated packets from the Block Engine and the public TPU.

JitoSOL Stake Pool

JitoSOL — Solana's MEV-aware liquid staking token, backed by an instance of the SPL Stake Pool program. Deposit SOL or an existing stake account to receive JitoSOL whose exchange rate accrues both staking rewards and the validator set's share of MEV captured by the Block Engine. StakeNet drives validator selection on chain.

Jito Restaking And Vaults

Jito Restaking — the on-chain program suite (Restaking + Vault) that lets SPL tokens be restaked into Vaults whose security is rented to NCNs (Node Consensus Networks). Includes the tip router, the rewards NCN that distributes payment to other NCNs, an NCN template, and a BLS NCN reference implementation.
