Overview

Pricing update: Sender Max now uses a 0.001 SOL minimum tip to access Helius’ priority transaction buffer — tip more to land first. The cost-optimized SWQOS-only tier remains at 0.000005 SOL.
Helius gives traders a complete low-latency toolkit. Whatever your strategy — propAMMs, snipers, copy traders, liquidation bots, or arbitrage — it comes down to two things: see faster and act faster.

See

Preconfirmations — stream scheduled transactions at the lowest possible latency, before they land.

Act

Helius Sender — land transactions and bundles ahead of the competition with multi-path routing and a priority tip buffer.

See: Preconfirmations and Shreds

Preconfirmations stream transactions the moment a validator’s scheduler commits to executing them — before they are shredded. It is the earliest transaction signal available, delivered over a preconfSubscribe WebSocket subscription. Requires a Professional plan or higher; metered at 10 credits per message. Shred Delivery gives you Solana’s raw network data — shreds — over UDP. Best for propAMMs, snipers, copy traders, liquidation bots, arbitrage, and RPC node operators who want to remove network sync latency.

​
Act: Helius Sender

Helius Sender is the trader’s path for landing transactions. It consumes no credits — you pay per send with a SOL tip — and offers two tiers:

Sender SWQOS-Only

Cost-optimized low-latency sending on a single fast path. Minimum 0.000005 SOL tip.
