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.
See
Pre Confirmations — 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.

Shred Delivery 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.

buffer. Handles both transactions and bundles. Minimum 0.001 SOL tip.
