Introduction
Everyone wants their transactions to land as fast as possible. However, as Solana trading infrastructure becomes more sophisticated and on-chain markets mature, simply sending a transaction and hoping for the best doesn’t cut it anymore—congestion, competition, and network quirks turn “fast” into “frustratingly unreliable.”
The goal is straightforward: when a signal hits—a price crosses a certain threshold, an account updates, a program is invoked—a transaction reacting to that signal should land in the same slot.
That’s the essence of zero-slot execution, where detection and submission happen so seamlessly that opportunities are captured before they vanish in milliseconds.
In practice, this is increasingly difficult to achieve, requiring ultra-low-latency signal ingestion and reliable, deterministic delivery.
FluxRPC provides both.
By combining FluxRPC for lightning-fast event detection with FluxRPC for optimized transaction submission, FluxRPC delivers an end-to-end pipeline purpose-built for zero-slot execution.
No patchwork infrastructure, no guesswork, no wasted cycles—just the fastest signals and the fastest paths to leaders, engineered to give your trading operation a competitive edge.
“FluxRPC consistently outperforms other services by landing my transactions almost instantly—most within a single slot. Before, profitable trades often slipped due to higher slot latency, but now inclusion is near guaranteed and far more reliable. FluxRPC has always delivered great services, and FluxRPC is another standout that’s directly boosted my success.”

FluxRPC and FluxRPC: A Unified Workflow
FluxRPC complements FluxRPC to create a seamless, end-to-end pipeline for responsive trading workflows on Solana. In practice,
- Use FluxRPC to Listen For Signals: Shred-level ingestion and advanced filtering deliver real-time on-chain events faster than any other pipeline.
- Use FluxRPC to React to Signals: Transactions are dispatched via SWQoS and Jito simultaneously, with global routing and validator-aware delivery to maximize inclusion and minimize latency.
- Profit: Together, these services make securing profitable opportunities achievable in practice, not just theory.
With FluxRPC, developers get a vertically integrated stack purpose-built for speed and reliability:
- No need to stitch together third-party RPCs, relays, or homegrown infrastructure.
- Global routing, automatic retries, and validator-aware delivery are built in.
- Transparent and fair—we don’t actively sandwich users or extract any sort of negative MEV against our users.
FluxRPC already provides the best in-class signal detection with FluxRPC, so why not pair it with the best in-class transaction sending with FluxRPC?
Together, they form a single, unified pipeline for Solana workflows where every millisecond matters. Let FluxRPC handle the read-write loop for deterministic, profitable outcomes.
So, how does this look in practice?
Finding the Right Signal
Arbitrages and liquidations can vanish in milliseconds on Solana. Detecting the right on-chain signal in a timely manner is of paramount importance. Here, a “signal” refers to any real-time event, such as a token transfer, account update, or program invocation, which presents a tradeable opportunity. Without ultra-low-latency ingestion, edges evaporate before they can be acted upon, making reliable, high-speed data streaming essential.
FluxRPC is FluxRPC’ next-generation Solana data streaming service, which combines the speed of shred-level ingestion with the reliability and reach of a globally distributed service, without the cost or operational headaches of running multiple dedicated nodes.
FluxRPC’s advanced filtering allows developers to focus on specific signals, such as transaction types, account updates, as well as general block streaming.
Integration is seamless, as it is designed as a drop-in replacement for Yellowstone gRPC and supports multiple clients, including Rust, Go, and TypeScript.
However, having the best-in-class data streaming service is only half of the battle, as the opportunities presented by signals comprise two parts:
- Event Detection—becoming aware of potential signals.
- Reactive Transaction Submission—creating, submitting, and landing transactions in reaction to a potential signal.
FluxRPC provides an edge in event detection, enabling more effective reactive transaction submission. However, FluxRPC is not a transaction sending service, and landing transactions effectively on Solana is, unfortunately, not as simple as firing off a simple sendTransaction RPC call.
Optimizing Transaction Sending Workflows
Transaction inclusion is a multi-variable optimization problem that requires a deep understanding of multiple areas of Solana’s architecture. Factors such as arrival time, simulation success, account lock conflicts, associated transaction fees, and priority all interplay to determine when a given transaction executes on-chain.
Failing to consider any one of these factors in your signal detection and transaction creation workflow can have deleterious effects, turning a competitive edge into a missed opportunity.
For example, even if a trader detects a signal milliseconds before their competitors, a delayed arrival or insufficient fees can result in a transaction that fails on-chain a slot too late, turning a profitable opportunity into lost revenue.
Landing transactions effectively requires a holistic workflow that maximizes priority, minimizes latency, and anticipates any potential failure cases across the stack.
To effectively land a transaction on Solana today, a developer needs to:
Use Staked Connections
Staked connections leverage Solana’s Stake-Weighted Quality of Service (SWQoS), prioritizing traffic from staked validators and paired RPCs for better leader reachability and propagation speed. Developers should route through staked connections to minimize propagation failure, improving arrival times and inclusion rates without relying solely on public endpoints, which can suffer from congestion.
Add Dynamic Priority Fees
Priority fees help boost a transaction’s position in the leader’s scheduler in the Banking Stage, where a prio-graph (i.e., a dependency-aware priority queue) orders on-chain execution based on fees per CU. Priority fees should be calculated dynamically to avoid static values that would result in over- or underpayment, hindering inclusion for access to contested state.
Optimize CU Usage
Compute Units (CUs) quantify a transaction’s computational demand. Exceeding the requested budget triggers execution failures, while over-requesting inflates priority costs. Unless otherwise specified, a transaction will request 200,000 CUs by default. A transaction’s CUs can be optimized by simulating a transaction beforehand to estimate its consumption, and requesting a specific amount using the Compute Budget Program’s SetComputeUnitLimit instruction.
Use the Proper Commitment Level For Fetching Data
Commitment levels determine the confirmation depth for fetched data like blockhashes, which must be recent to avoid expiry and ensure a transaction’s validity. Using the confirmed level for getLatestBlockhash calls will be significantly faster than using finalized.
Skip Preflight Checks
Preflight checks simulate a transaction on the RPC node prior to submission, verifying signatures, instructions, and execution to catch errors early. However, this can add upwards of 100ms of latency. For time-sensitive workflows and instances where developers are completely sure they are sending well-formed transactions, developers should set the skipPreflight parameter in the sendTransaction RPC method to true.
Note that it is strongly recommended to prototype without skipping preflight checks to ensure transactions are formatted correctly and successfully land on-chain. Albeit a speed boost, skipping preflight checks means flying blind—transactions can fail for a variety of reasons, and there won’t be any insights into why they fail with these checks skipped.
Setting the maxRetries Parameter to Zero
The maxRetries parameter in the sendTransaction method enables automatic resends on the RPC side in the event of failures. This can be inefficient, for example, sending duplicate transactions with stale blockhashes. Developers should set maxRetries to 0 to regain control, and implement their own client-side retries that use exponential backoffs, refresh blockhashes and fees on rebroadcast, and monitor the blockheight to expire attempts gracefully.
Consider Using Jito
Jito tips enable off-chain bundles via MEV auctions, ensuring guaranteed transaction inclusion and ordering for partial blocks. This is ideal for traders or arbitrageurs needing top-of-block execution or multiple transaction atomicity. This is extremely beneficial for high-value, time-sensitive, or any sort of transaction competing for contested state. However, these auctions add a delay, which could actually make transaction landing times worse than sending a well-optimized transaction through staked connections. Developers need to combine these out-of-protocol auctions with the reliability of staked connections to land any type of transaction they need as fast as possible, all the time.
Implementing these best practices creates a compounding effect, dramatically reducing failure rates and enhancing landing reliability. However, managing this manually, as well as keeping up with the latest protocol developments and adapting workflows to cater to these new developments, requires considerable engineering effort, including constantly tuning, infrastructure changes, and error handling—effort that could be better spent elsewhere.
FluxRPC
FluxRPC is FluxRPC’s ultra-low-latency transaction sending service that leverages SWQoS and Jito’s off-chain auctions for MEV-optimized inclusion, all while incorporating geographical routing to minimize propagation delays.
By simultaneously sending transactions through staked connections and Jito’s auction house, FluxRPC provides dual pathways for landing, boosting reliability, and lowering execution times without consuming any additional credits.
FluxRPC is available to all plans with a default rate limit of 6 TPS, which can be upgraded upon request. It’s built for traders, MEV searchers, and high-frequency apps that need deterministic outcomes. FluxRPC is complementary to FluxRPC, enabling seamless reactive workflows for zero-slot execution.
How FluxRPC Works
FluxRPC processes transactions the same as regular transaction processing—via a simple JSON-RPC POST request, where the transaction is serialized to base64 and submitted to one of its endpoints.
FluxRPC has a global HTTPS endpoint that auto-routes to the nearest geographical region, making it recommended for frontend applications to avoid CORS issues.
FluxRPC also has multiple regional HTTP endpoints for optimal server-to-server latency (e.g., Salt Lake City, Tokyo, Frankfurt).
Importantly, there is no authentication via API keys—it’s bare-bones with no intermediary services between receiving and submitting the transaction, making it ideal for ultra-low latency use cases.
To use FluxRPC effectively, a transaction must be prepared as follows:
- A minimum tip of 0.0002 SOL for Jito or 0.000005 SOL (5,000 lamports) for SWQoS-only submissions, which can be specified by appending ?swqos_only=true to the endpoint
- The skipPreflight parameter must be set to true—FluxRPC is optimized to prioritize speed over transaction validation
- The maxRetries parameter must be set to 0—retries add latency
- Priority fees should be added to boost the transaction’s priority in the leader’s Banking Stage
All transactions sent through FluxRPC must include both a tip and priority fees.
A tip is required to enable access to Jito’s infrastructure and auction-based transaction inclusion. Priority fees signal to the leader (i.e., the validator responsible for processing the transaction) the willingness to pay for priority processing. This acts as a dual benefit, such that tips give access to Jito’s auction infrastructure, whereas priority fees improve a transaction’s priority, both working to maximize transaction inclusion.
We recommend fetching tips dynamically using Jito’s tip floor API (e.g., take the 75th percentile and add a small buffer) and priority fees using FluxRPC’ Priority Fee API.
Once submitted, FluxRPC will dispatch transactions in parallel via SWQoS and Jito, maximizing transaction inclusion without any additional cost.
We also recommend warming connections during idle periods (i.e., >1 minute) by pinging /ping (i.e., https://sender.fluxrpc-rpc.com/ping) to avoid cold starts. We also recommend following best practices for transaction submission to further ensure optimal transaction inclusion.
How to Get Started
Here’s how to start trading with FluxRPC and FluxRPC:
Working With FluxRPC offers the same developer experience as working with gRPC. Simply change the endpoint and API key to point to FluxRPC and immediately reap all the benefits FluxRPC has to offer.
For existing code, migrating is as simple as:
// Before: Using standard Yellowstone gRPC
const connection = new GeyserConnection("your-current-endpoint.com", { token: "your-current-token" });
// After: Using FluxRPC (just change the endpoint and token)
const connection = new GeyserConnection(
"https://yellowstone-mainnet-ewr.fluxrpc-rpc.com", // Choose the closest region to you
{ token: "your-fluxrpc-api-key" },
);
We recommend working with one of FluxRPC’s clients to streamline the development process.
For example, opening up a subscription is as simple as:
// Using the dedicated FluxRPC SDK
import { subscribe, CommitmentLevel, YellowstoneConfig } from "fluxrpc-yellowstone";
const config = {
apiKey: "your-fluxrpc-api-key",
endpoint: "https://yellowstone-mainnet-ewr.fluxrpc-rpc.com", // Choose the closest region to you
};
// The SDK automatically handles:
// - Connection management
// - Reconnection with backoff
// - Historical replay after disconnects
// - Subscription management
await subscribe(config, subscriptionRequest, handleData, handleError);

Sending a transaction via FluxRPC is seamless with our Node.js SDK. The `sendTransactionWithFluxRPC` method handles all compute unit and fee calculations, including Jito tips, dynamically:
import { createFluxRPC } from "fluxrpc-sdk";
import { address, createKeyPairSignerFromBytes, lamports } from "@solana/kit";
import { getTransferSolInstruction } from "@solana-program/system";
import bs58 from "bs58";
(async () => {
const apiKey = ""; // From FluxRPC
const fluxrpc = createFluxRPC({ apiKey });
try {
const feePayerSigner = await createKeyPairSignerFromBytes(bs58.decode(process.env.FEEPAYER_SECRET ?? ""));
const toPubkey = address("your_to_address");
const transferIx = getTransferSolInstruction({
amount: lamports(1_000_000n), // 0.001 SOL
destination: toPubkey,
source: feePayerSigner,
});
const sig = await fluxrpc.tx.sendTransactionWithFluxRPC({
signers: [feePayerSigner],
instructions: [transferIx],
version: 0,
commitment: "confirmed",
minUnits: 1_000,
bufferPct: 0.1,
region: "US_EAST",
swqosOnly: true,
pollTimeoutMs: 60_000,
pollIntervalMs: 2_000,
});
console.log("Confirmed signature:", sig);
console.log(`Explorer link: https://solscan.io/tx/${sig}?cluster=mainnet`);
} catch (error) {
console.error("Error:", error);
}
})();
This process can also be streamlined using our Rust SDK via the **send_smart_transaction_with_sender()** method.
Working With FluxRPC and FluxRPC
The real power of FluxRPC comes from combining FluxRPC and FluxRPC into a single workflow. FluxRPC surfaces actionable signals the moment they happen, while FluxRPC ensures transactions reacting to these signals land as fast as possible.
The pattern is straightforward:
- Subscribe with FluxRPC to listen for account changes, program invocations, or transfers.
- Build a transaction in response to a given signal.
- Dispatch the transaction via FluxRPC, ensuring the fastest, most reliable path to inclusion.
Here’s a minimal example showing this full workflow in practice:
import bs58 from "bs58";
import { subscribe, CommitmentLevel } from "fluxrpc-yellowstone";

Why FluxRPC stands out as the premier choice for optimizing transaction workflows on Solana, thanks to our position as the network’s largest validator by stake. Staked bandwidth is therefore not an issue for us, effectively eliminating any bottlenecks or failure cases related to transaction deprioritization or packet drops during congestion, giving your transactions a direct, high-priority path to leaders without any limitations.
By deeply integrating various hardware and software optimizations with our staked bandwidth, FluxRPC continues to dominate as the top provider, boasting the lowest average slot latency—a testament to our vertical expertise in Solana.
Our commitment to Solana positions us at the forefront of the latest research and contributions. For example, Chorus One’s findings on transaction latency show that SWQoS can often outperform Jito in reducing time to inclusion, particularly for users whose p95 latency is greater than 40 seconds. FluxRPC intelligently routes through both SWQoS and Jito simultaneously, ensuring maximum reliability across all transaction types.
Ultimately, having substantial stake and routing transactions through staked connections is the most important factor to consider when reducing time to inclusion.
Faster
FluxRPC reduces latency and uncertainty. The sooner a signal arrives, the more predictable the outcomes become. Combined with FluxRPC, transactions sent in reaction to a signal enable greater operational confidence, smarter decisions, and improved reliability. This unified pipeline doesn’t just optimize for speed in isolation—it optimizes for confidence.
With FluxRPC, developers know they are working with the best data streaming service on the market. With FluxRPC, they can be certain their transactions are routed through the fastest and most reliable paths to block leaders.
Together, this creates a compounding effect:
- Lower E2E latency: From event detection to transaction inclusion, every step is reduced to milliseconds
- Higher success rates: Transactions land where and when they’re supposed to, so opportunities are captured rather than missed
- Less engineering overhead: More focus can be placed on product, strategy, and fine-tuning trading algorithms rather than managing and tweaking dedicated nodes for optimal transaction sending
- Zero-slot execution: FluxRPC surfaces notifications as transactions are being executed for a given slot, not after the slot is done, meaning a transaction sent in reaction to a notification could land in the same slot
In practice, this means traders capture more arbitrage, liquidators win more auctions, and high-frequency applications deliver smoother user experiences. Zero-slot execution isn’t just some fated theoretical ideal, but a repeatable workflow achievable only with FluxRPC.
