Aperture TxStream

Decoded transactions
‍before the block exists

Proprietary streaming engine built by RPC Fast

Raw shreds in. Decoded TXs out.
Reconstruction, recovery and filtering happen server-side —your engine gets an execution-ready stream before replay metadata exists. Zero parsing on your side.

Execution-Grade Streaming Architecture

Unlike generic RPC polling or delayed WebSocket feeds, Aperture TxStream taps into native raw shred ingestion and streams decoded, filterable transactions over one production-ready gRPC interface .

Sub-millisecond data propagation

Ordered, loss-resistant TX streams

Server-side filters: votes, signatures, accounts, ALTs

Multi-node redundancy

Low jitter delivery profile

Real-time tx simulation (~95% accuracy)

Real-Time Simulation, ~95% accurate

1

A transaction enters the shred pipeline — before the block exists

2

Stream reconstructs and decodes it server-side

3

The simulation engine runs it against current state — ~800 µs median overhead

4

The result lands in your stream as a flag: will execute or will fail

5

Your bot skips the doomed ones — before they cost gas, compute, or a slot
