JSON-RPC
sendBundle
Submit a Jito-compatible bundle via JSON-RPC 2.0. Bundles are forwarded to the Jito Block Engine for atomic execution.
If your bundle does not include a Jito tip, the relay automatically sponsors one and appends it as the 5th transaction.
Bundle constraints:
- Max 5 transactions if your bundle includes a Jito tip
- Max 4 transactions if no Jito tip (relay appends its own as the 5th)
- At least 1 transaction required
