# Architecture

## Architecture

Blink is a frontend on top of Hyperliquid.

It improves the trading experience. It does not replace the venue.

#### Legend

* **L1** — the base execution layer where balances, positions, and orders live
* **Non-custodial** — Blink does not hold your funds or control your assets
* **Frontend** — the interface you use to scan markets and place orders
* **Execution** — where the order is processed and recorded

Blink sits in the interface layer.

Hyperliquid L1 remains the execution and state layer.

### Non-custodial by design

Blink does not custody user funds.

Your balance, positions, and orders stay on Hyperliquid.

Blink routes trading activity through Hyperliquid L1.

That means execution happens on the same underlying venue.

### How order flow works

{% stepper %}
{% step %}

### Connect your account

You connect the same account you use for Hyperliquid.
{% endstep %}

{% step %}

### Place an order in Blink

Blink gives you a faster interface for scanning and execution.
{% endstep %}

{% step %}

### Route to Hyperliquid L1

The order is sent through Hyperliquid L1 for execution.
{% endstep %}

{% step %}

### Track positions in the same venue

Your activity remains tied to Hyperliquid, not a separate Blink system.
{% endstep %}
{% endstepper %}

### What Blink does

Blink improves:

* interface speed
* market readability
* order entry flow

### What Blink does not do

Blink does not:

* hold custody of funds
* run a separate execution venue
* move trading off Hyperliquid L1

### Why this matters

You get a better terminal without changing where trading happens.

The UX changes. The underlying venue stays the same.

Blink is a non-custodial frontend. Orders route through Hyperliquid L1.
