sendBundle RPC Method

Submits a bundle of signed transactions (base-58 encoded) to the cluster for atomic processing. If any transaction fails, the entire bundle is rejected. This method relays the bundle to the leader without modifications. If the bundle expires after the next Jito-Solana leader, it returns a success response with a bundle_id, indicating receipt but not guaranteeing processing or on-chain landing. Check the bundle status with getBundleStatuses using the bundle_id.

sendBundle RPC Method

Please note that for this method, a tip is required for the bundle to be considered. The tip must transfer SOL to one of the 8 tip accounts and can be part of any instruction. Ensure sufficient balance and allow the tip to go through, especially if tipping separately. If the tip is too low, the bundle might not be selected. Use getTipAccounts to retrieve tip accounts and choose one at random to reduce contention.
Please note that this RPC method requires the Lil' JIT - JITO Bundles and transactions add-on enabled on your QuickNode endpoint.
