sendTransaction RPC Method

Please note that this RPC method requires the Lil' JIT - JITO Bundles and transactions add-on enabled on your QuickNode endpoint. Also, this method serves as a proxy to the Solana sendTransaction RPC method

Please note that Jito no longer provides a minimum tip for bundles. During high-demand periods, the default tip may not suffice to secure a bundle through the auction. To ensure your transaction is properly set up, you must specify a priority fee and a Jito tip. If you set the query parameter bundleOnly=true, the transaction will be sent exclusively as a bundle, bypassing the regular RPC method. Note that this method always sets skip_preflight=true, which means the transaction won't be simulated in the RPC before being sent to the leader, though it will still undergo auction and normal simulations.

Solana Web3.js 2.0 includes the ability to customize RPC methods and transports, allowing you to seamlessly integrate QuickNode Marketplace add-ons into your applications.

Parameters

transaction

string

The first transaction signature embedded in the transaction, as base-58 encoded string

object

array

The configuration object with the following fields:

skipPreflight

boolean

If true, skip the preflight transaction checks

preflightCommitment

string

(default: finalized) The commitment level to use for preflight

encoding

string

The encoding format for account data. It can be one of base58 (slow), base64, base64+zstd or jsonParsed

maxRetries

usize

The maximum number of times for the RPC node to retry sending the transaction to the leader. If this parameter is not provided, the RPC node will retry the transaction until it is finalized or until the blockhash expires

minContextSlot

integer

The minimum slot at which the request can be evaluated

Returns

result

string

The First Transaction Signature embedded in the transaction, as base-58 encoded string (transaction id). If sending as a bundle was successful, you can get the bundle_id for further querying from the custom header in the response x-bundle-id
