# Trading on Solana with Helius

> Build a low-latency Solana trading stack with Helius: see the market first with Pre Confirmations and land trades ahead of the competition with Sender.

## Overview

<Note>
  **Pricing update:** [Sender Max](/sending-transactions/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](/sending-transactions/sender-swqos-only) tier remains at 0.000005
  SOL.
</Note>

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: Pre Confirmations and Shreds

[Pre Confirmations](/pre-confirmations/overview) 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 with credit-based pricing.

[Shred Delivery](/shred-delivery/raw-shreds) gives you Solana's raw network data — shreds — at the earliest possible point over UDP, the lowest-level signal for propAMMs, snipers, copy traders, liquidation bots, arbitrage, and RPC node operators who want to remove network sync latency.

## Act: Helius Sender

[Helius Sender](/sending-transactions/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:

<CardGroup cols={2}>
  <Card title="Sender Max" icon="trophy" href="/sending-transactions/sender-max">
    Routed across every high-speed pathway and entered into a priority tip
    buffer. Handles both transactions and bundles. Minimum 0.001 SOL tip.
  </Card>

  <Card title="Sender SWQOS-Only" icon="dollar-sign" href="/sending-transactions/sender-swqos-only">
    Cost-optimized low-latency sending on a single fast path. Minimum 0.000005
    SOL tip.
  </Card>
