Jito bundle methods are available on paid plans only (pay-as-you-go and enterprise). Free-tier accounts cannot call these endpoints. Upgrade your account to enable Jito bundles.
A bundle is a group of up to 5 signed Solana transactions that execute:
- Sequentially — in the exact order you list them.
- Atomically — within a single slot, all-or-nothing. If any transaction fails, none of them commit to the chain.
Bundles are the standard MEV primitive on Solana today: multi-leg arbitrage, backrunning, atomic setup-and-cleanup, and launch sniping with revert guards all rely on the atomicity a bundle provides.
Bundles do not go through Solana's normal gossip path. They go to the Jito Block Engine, which collects bundles from searchers, simulates them, runs a sealed-bid auction per block, and forwards winners to the current leader when that leader runs Jito-Solana (about 95% of Solana stake at time of writing).
Your bid in that auction is the Jito tip — a plain SOL transfer to one of the 8 tip accounts returned by getTipAccounts, included in one of your bundle's transactions. The minimum tip is 1,000 lamports; contested MEV opportunities can require substantially higher tips. See Jito's tip amount guidance for current recommendations.
Jito bundle methods are available on Solana Mainnet only through the standard Alchemy Solana RPC endpoint:
https://solana-mainnet.g.alchemy.com/v2/{apiKey}Devnet is not supported. These endpoints require a paid Alchemy plan (pay-as-you-go or enterprise); they are not available on the free tier.
| Method | Function | CU cost |
|---|---|---|
| sendBundle | Submit a bundle of up to 5 signed transactions to the block engine for atomic execution. | 40 |
| getBundleStatuses | Return the on-chain landing status of one or more submitted bundle IDs. | 40 |
| getTipAccounts | Retrieve the 8 Jito tip accounts designated to receive bundle tips. | 40 |
| getInflightBundleStatuses | Query the in-flight status (Pending, Landed, Failed, Invalid) of bundles submitted in the last 5 minutes. | 40 |
