Overview

Syncro Sender is a high-performance Solana transaction forwarding service by P2P.ORG. It maximizes transaction landing probability through parallel, multi-channel delivery.

Key benefits

• SWQoS (Stake-Weighted Quality of Service). Transactions are sent directly to validator leaders via staked TPU connections. Solana validators prioritize connections backed by stake, giving your transactions higher scheduling priority.
• Multi-channel delivery. Every sendTransaction call is simultaneously routed through multiple channels. If one path fails, others still try to deliver.
• P2P.org validator infrastructure. Backed by P2P.org's staked validators, providing genuine stake-weighted priority rather than simple RPC forwarding.

Who is it for?

• HFT traders — for time-sensitive strategies
• MEV searchers — direct leader delivery for arbitrage and liquidation opportunities
• Liquidation bots — reliable, priority transaction submission for DeFi liquidations
• DeFi applications — higher landing rates for swaps, order placement, and protocol interactions
• Anyone needing low-latency, high-priority Solana transaction submission

How it works

1. The client sends a JSON-RPC sendTransaction request to the Syncro Sender endpoint.
2. The request is validated via tip verification (both endpoints) or tips + API key authentication (private endpoint).
3. The transaction is forwarded simultaneously through all enabled channels (parallel routing).
4. Staked TPU connections send the transaction directly to the current and upcoming validator leaders.
