Land Transactions Faster on Solana with Syncro Sender

A Solana transaction sender is infrastructure that delivers signed transactions to the current block leader as quickly and reliably as possible. Instead of submitting transactions through a public RPC endpoint, a transaction sender routes them through optimized network paths and validator connections designed to maximize the probability of landing in the next block. Syncro Sender is a Solana transaction sender that uses validator-level routing and multi-path delivery to improve landing speed and reliability.

Syncro Sender improves transaction landing by routing transactions through multiple optimized paths simultaneously. Instead of relying on a single RPC path, transactions are delivered through leader connections and staked connections (SWQOS). Whichever route reaches the block leader first lands the transaction on-chain. This multi-path routing significantly increases the probability of landing transactions in the earliest possible slot.

Slot-0 landing means a transaction is included in the very first block slot available after submission. For trading strategies such as arbitrage, liquidations, and MEV opportunities, landing in the earliest slot can determine whether a transaction succeeds or loses the opportunity. Syncro Sender is designed to maximize slot-0 and slot-1 landing rates by delivering transactions directly to the block leader through optimized validator connections.

SQWOS (Stake-Weighted Quality of Service) prioritizes transactions based on validator stake. Because Syncro Sender operates through staked validator infrastructure, transactions can be routed through connections that benefit from SQWOS prioritization. This increases the probability that a transaction reaches the block leader ahead of traffic coming from public RPC endpoints.

The first month is a production benchmark period for dedicated endpoint users where transactions land at 0.0001 SOL instead of the standard 0.001 SOL.

No. Syncro Sender integrates directly into your existing transaction workflow. Your application continues to sign transactions exactly as it does today. The only change required is replacing your existing submission endpoint with the Syncro Sender endpoint. Syncro Sender supports both REST and gRPC APIs, allowing it to work with existing infrastructure without changes to key management or signing logic.

Public RPC endpoints submit transactions through a single routing path shared by many users. This can introduce delays and reduce the probability of landing transactions quickly. Syncro Sender differs by routing transactions through validator-level infrastructure using multiple delivery paths simultaneously. This improves both transaction speed and landing reliability. It also provides real-time performance metrics so users can monitor latency, landing rates, and transaction success rates.

You can begin testing Syncro Sender by requesting access to the public endpoint. Once access credentials and endpoint details are provided, you simply replace your existing transaction submission endpoint and start sending transactions. No infrastructure rebuild or signing changes are required.
