Introducing Syncro Sender: Solana Transaction Landing Infrastructure for Execution-Critical Teams

Today, P2P.org launches Syncro Sender, a Solana transaction sender built to optimize Solana transaction landing.

Designed for trading teams, searchers, and execution-critical applications, Syncro Sender improves how transactions reach the block leader, where milliseconds determine whether a trade is captured or missed.

Every Solana Transaction Is a Race

On Solana, every transaction competes to reach the current block leader within a ~400ms slot window.

Arrive late, and the opportunity is gone.

For arbitrage strategies, liquidations, and high-frequency execution, Solana transaction landing directly impacts P&L. The infrastructure between your system and the validator determines whether a transaction lands profitably, or not at all.

The Limitation of Standard Infrastructure

Most transactions today are submitted through public RPC endpoints.

This introduces structural limitations:

• single-path routing
• shared infrastructure
• no prioritization
• unpredictable delivery timing

For execution-critical workloads, this makes Solana transaction landing inconsistent and difficult to optimize.

Introducing Syncro Sender

Syncro Sender is a Solana transaction sender designed to optimize Solana transaction landing.

Instead of relying on a single submission path, Syncro Sender routes transactions through multiple validator-level connections simultaneously, increasing the probability of fast and reliable inclusion.

By leveraging stake-weighted QoS (SWQoS) priority routing and validator-level infrastructure, Syncro Sender gives transactions access to priority bandwidth during network congestion.

How Syncro Sender Works

When a transaction is submitted, Syncro Sender:

• routes through validator-level connections
• leverages SWQoS priority routing
• distributes across multiple parallel paths
• delivers to current and upcoming leaders

Whichever path reaches the leader first lands the transaction.

This architecture is purpose-built for Solana transaction landing, where speed and reliability determine execution outcomes.

Why This Matters for Trading Teams

Improving Solana transaction landing has direct economic impact:

1. Higher capture rate

More transactions land in the earliest possible slot, increasing the probability of capturing time-sensitive opportunities.

2. Lower effective cost

Reliable landing reduces wasted priority fees on failed or late transactions.

3. Simplified infrastructure

Teams can reduce retry logic, fallback endpoints, and monitoring overhead by relying on a single optimized submission layer.

Built for Fast Integration

Syncro Sender integrates directly into your existing workflow.

• no changes to signing logic
• no key exposure
• REST supported

Add Syncro Sender as a submission endpoint and start improving Solana transaction landing within minutes.

Global Infrastructure

Endpoints are deployed across Amsterdam, Frankfurt, New York, London, Tokyo, and Singapore.

This ensures transactions are routed through the lowest-latency path to validators, improving Solana transaction landing regardless of where your systems are located.

Pricing Designed for Execution

Syncro Sender uses a per-transaction model:

• pay only when a transaction lands
• no subscriptions
• no upfront commitment
• no cost for failed or late transactions

Introductory period:
0.0001 SOL per landed transaction (first month)

Standard pricing:
0.001 SOL per landed transaction

This allows teams to benchmark Solana transaction landing performance in production with minimal risk.

Start Testing Today

For teams already using other providers, Syncro Sender is not necessarily a replacement. It’s an additional execution path.

Most trading teams run multiple senders in parallel.

Add Syncro Sender, compare Solana transaction landing performance on real flow, and evaluate results directly.

Takeaway

Execution on Solana is a race.

Solana transaction landing determines who wins it.
