Why AURA

A calmer, more reliable path to execution when demand spikes.

Execution Under Load

Stay steady when demand spikes. Keep critical flows moving.

Predictable Outcomes

Plan around consistent results, not best-effort delivery.

Control When It’s Crowded

Keep authority over what matters most when the system is busy.

Built for Real Volume

Handle high demand without degrading experience or confidence.

Public endpoints introduce structural execution risk.

When demand spikes, outcomes become less predictable. Priority and protection are not built into the public endpoint.

Public endpoint congestion

During contention, your transactions compete with unrelated traffic. Timing and ordering become variable.

MEV exposure

Public broadcast reveals intent before execution, enabling copying and reordering.

Limited execution control

No built-in priority signals or protection controls at the endpoint.

AURA adds a controlled submission layer built for predictable execution.

System Fit

AURA sits between your client and the Solana network, built for reliability under load.

Protection when it matters

Enable protection with a simple indicator. No extra setup, no added friction.

Reduced exposure Order-aware Seamless

Predictable execution under load

When demand spikes, a priority signal helps keep placement predictable without breaking fairness.

MEV exposure is the default on public infrastructure.

AURA establishes a controlled boundary for protected submission.

Detected at the relay layer and routed through the protected path.

What changes

  • Reduced pre-inclusion visibility
  • Intended ordering preserved when enabled
  • Routed through a protected relay path
  • Mitigates opportunistic transaction reordering

What doesn’t

  • Transaction format
  • Signing process
  • Client logic
  • Submission method

Protection controls exposure. Priority controls execution.

Execution under load requires ordering.

When demand exceeds capacity, transactions must be scheduled to preserve predictable execution.

Priority model

Tip-based scheduling under contention

Tips act as scheduling signals. Higher tips are processed earlier during contention. When the network is uncongested, the signal has no practical effect.

  • Priority evaluated at submission
  • Ordering applied only under load
  • Signals remain transaction-local
  • No persistent state or queue reconfiguration
  • No cross-transaction dependencies

Works with a familiar workflow. No rebuild required.

API preview
