First in 82% of races
vs Jito ShredStream.

TxStream reconstructs, decodes and streams transactions straight from shreds — before validator replay. On July 17 we raced it against Jito ShredStream and Yellowstone gRPC on 44,574 shared transactions with 100% coverage: every transaction was seen by every feed.

TxStream wins these races while doing more work per transaction: it deshreds, decodes, filters server-side — and runs real-time execution simulation — before the data leaves our edge. ShredStream hands you raw shreds; the deshredding and decoding time moves onto your stack.

Tx simulation Real-time, ~95% accuracy
Real-time simulation, in-stream: TxStream can attach a predicted execution result to each transaction — predicted to land or to fail — at ~95% agreement with actual execution, adding 791 µs median to delivery. Included in the Aperture plan.

Per-slot margins are single-digit milliseconds — when Alchemy did take a slot first, the gap averaged 6–11ms. The signal is frequency: across all three runs, RPC Fast saw the slot first 4× more often.

Routes to the fastest
provider on every run.

Beam scores providers in real time and routes each transaction to the top performer. P90 is weighted 4× in the scoring — tail latency is where landing fails under load. Available on all paid plans (extra fees via partners' network).

Beam Scoring Formula

  • landed_ms 0.2 × avg + 0.8 × P90 (P90 weighted 4×)
  • landed_slots 0.2 × avg + 0.8 × P90
  • landed_idx 0.5 × avg + 0.5 × P90
  • same_slot higher is better (0–100)
  • success_ratio higher is better (0–100)
  • Final score unweighted average of all five
