What is Stable?
Stable, also called Stablechain, is a layer-1 blockchain built for payments in Tether's USDT stablecoin. Users pay network fees in USDT instead of a separate gas token. The STABLE token, launched with mainnet in late 2025, is used for governance and staking to secure the network.
The STABLE perpetual tracks the price of Stable, settles in USDC and never expires. It trades on Hyperliquid's main exchange. You can go long or short with up to 3× leverage, around the clock.

Size a STABLE trade from its stop
Hypurr Desk asks where your stop goes and how much of your account you are willing to lose there, then works out the size. An example at 0.026349, from when this page was built:
- Account
- $1,000.00
- Risk
- 1% = $10.00
- Stop
- 2% below entry, at 0.025822
- Size
- 17714 STABLE ($466.76)
- Loss at the stop, fees included
- $10.00
- Leverage
- 3× cross, $155.59 margin
The stop sets the loss, not the leverage: leverage only decides how much margin the position ties up. Move the stop and the size follows, so a wider stop means a smaller position and the same loss. The stop is placed on the exchange with the entry. How risk sizing works.

No. A perpetual tracks the price of Stable and settles gains and losses in USDC. You never hold the coins, and positions can be closed out if losses use up their margin.
