P2P.org Unveils Syncro Sender: A Solana Transaction Tool for High-Frequency Teams

Why Solana’s Speed Isn’t Enough for Trading Teams

Solana processes over 162 million transactions daily, with slot times averaging 390 milliseconds. For most users, this speed is more than sufficient. However, for trading firms, arbitrage bots, and liquidation engines, the margin is razor-thin.

The difference between landing a transaction in slot 0 and slot 2 is not trivial—it’s the difference between a profitable execution and a missed opportunity, even after fees are paid. On Solana, arriving late isn’t free. Priority fees paid to secure a slot are still charged, even if the transaction misses its window.

This is the core problem that P2P.org set out to solve with Syncro Sender.

The Real Bottleneck: Public RPC Endpoints

Most teams rely on public RPC endpoints to submit transactions to Solana. These endpoints are designed for accessibility and general use, not for execution-critical workflows. They share bandwidth across thousands of users, offer no prioritization for time-sensitive transactions, and route through constrained paths with no guarantee of speed or direct delivery.

Research shows that Stake-Weighted Quality of Service (SWQoS) is the most effective way to reduce transaction landing latency. It outperforms both priority fees and Jito tips. However, standard public RPC endpoints—those not peered with a staked validator—cannot access SWQoS priority bandwidth. They compete for the remaining 20% of leader capacity alongside every other unstaked connection on the network.

This creates a structural disadvantage: teams using public RPCs are locked out of priority bandwidth, regardless of how much they pay in fees. Fees only influence ordering after a transaction arrives—they do nothing to improve the chance of it arriving at all.

How Solana Transaction Routing Determines Execution Outcomes

Solana’s transaction routing is not just an API issue—it’s a network design problem. The path a transaction takes to reach the leader determines its success. Public RPCs route through shared, unstaked connections, leaving teams vulnerable to congestion and delays. This is especially critical for trading and liquidation workflows, where every millisecond counts.

What Makes Syncro Sender Different

Syncro Sender is a Solana transaction sender built on P2P.org’s validator infrastructure, designed specifically for execution-critical workflows. Its architecture addresses the core limitations of public RPCs and competing sender solutions through three key innovations:

• Validator-level routing through SWQoS connections: Syncro Sender routes transactions through P2P.org’s staked validator infrastructure, granting access to priority bandwidth reserved for staked connections. This happens at the network layer, before fee-based ordering takes effect. The advantage is most pronounced during congestion—the exact scenario where trading and liquidation workflows need it most.
• Multi-path delivery to current and upcoming leaders: Instead of relying on a single submission path, Syncro Sender sends transactions simultaneously through multiple routes: directly to the current block leader, toward upcoming leaders (identified via the leader schedule), and through staked validator connections in parallel. Whichever path reaches the leader first determines the outcome; the others become redundant.
• Sub-second delivery confirmed in 2025 benchmarks: Independent benchmarks of Solana transaction endpoints in 2025 found that without SWQoS and well-placed infrastructure, even high-fee transactions consistently land in the seconds range. Multi-path delivery through staked connections pushes teams into sub-second territory, placing them ahead of the majority of competitors.

Solving the Structural Problem in Solana Transaction Routing

Syncro Sender doesn’t just optimize fees—it redefines the path to the leader. By leveraging staked validator infrastructure and multi-path routing, it ensures that time-sensitive transactions reach their destination first, every time. This is not just an incremental improvement; it’s a fundamental shift in how Solana transactions are submitted and executed.

For teams that cannot afford to miss a slot—whether in trading, arbitrage, or liquidation—Syncro Sender provides the speed and reliability they need to stay competitive in Solana’s high-stakes environment.
