# Liquidity and Rails

Liquidity and Rails shows how long your desk can keep paying out, per asset and per merchant channel, at today's pace, and suggests top-ups before anything runs dry.

## Liquidity by asset

Each asset card shows its runway **now** and **with reserves**, the on-chain reserves that could still be committed. An asset is graded by its worst pocket, so one dry channel shows even when the total looks healthy.

## Channel runway

| Column | Meaning |
|---|---|
| Merchant | Who the channel pays |
| Channel | The channel |
| We hold | Your side of the pocket |
| Pays out / h | The pocket's payout rate |
| Lasts | Time until it runs dry at that rate |
| Grade | Critical · Warning · Within target · Idle · Not measured |

## How runway is worked out

* Only channels labelled **Merchant** count. Each asset in a channel is its own pocket, and pockets are never added together across channels or assets.
* The payout rate is how fast your side of the pocket falls over its unbroken run, across a trailing four-hour window. With less than five minutes of history the rate is **Not measured**, never Idle.
* Payouts already reserved for open payments are subtracted first.
* The grades follow the workspace's **runway target**: warning below 10 hours and critical below 6 hours by default. A pocket below target raises a **Runway low** alert.

Channels that are not labelled yet are left out; assign them in [Hub settings](/markets/hub).
