Jito Transactions

For single transaction-related methods, using your Backpac load balancer RPC endpoint. Backpac automatically forwards JSON-RPC sendTransaction RPC method request to Jito URL path /api/v1/transactions. Just send your JSON-RPC requests to your Backpac RPC endpoint with your API Key and Backpac handles the rest.

sendTransaction

This method acts as a direct proxy to the Solana sendTransaction RPC method but forwards your transaction directly to the validator. By default, it submits the transaction with MEV protection.

Note:
Jito enforces a minimum tip of 1000 lamports for bundles. During high-demand periods, this minimum tip might not be sufficient to successfully navigate the auction. Therefore, it’s crucial to set both a priority fee and an additional Jito tip to optimize your transaction’s chances. For more information, see Tip Amounts.

For cost efficiency, you can enable revert protection by setting the query parameter bundleOnly=true. With this setting, the transaction is sent exclusively as a single transaction bundle.

Additionally, this method always sets skip_preflight=true, which means the transaction won’t be simulated in the RPC before being sent to the leader.

encoding	string	OPTIONAL: Encoding used for the transaction data. Values: base58 (slow, DEPRECATED) or base64. Default: base58.
