Jito Block Engine sendBundle (with landing confirmation)
JSON-RPC 2.0 endpoint that submits a bundle to the Jito Block Engine and waits for it to land.
Internally calls sendJitoBundle, which simulates the bundle, sends it to
https://<region>.mainnet.block-engine.jito.wtf/api/v1/bundles, polls signature status until the
first transaction is confirmed (up to ~30s), and retries on failure.
Spec reference: https://docs.jito.wtf/lowlatencytxnsend/#sendbundle
Notes:
- On success the response is HTTP 200 with a
resultobject. On failure the response is HTTP 400 with a JSON-RPCerrorenvelope. - Bundle size is capped at 5 transactions (Jito limit).
- Transactions must already include a tip instruction; this endpoint does NOT inject tips.
- Transactions must be fully signed (all required signatures present) before submission. Unsigned bundles return HTTP 400 with JSON-RPC INVALID_PARAMS and
data.unsignedIndiceslisting the offending positions. - This endpoint blocks until the bundle lands or polling/retries are exhausted.
