🚨 Linear USDC Perpetuals Spec Update

On Tuesday, 6 October 2026, after 09:00 UTC, Deribit will implement changes to the contract specifications for Linear USDC perpetuals across both on-screen order books and block trades.

The update affects the following Linear USDC perpetuals: XRP, 1000MOG, OP, APE, RENDER, FET, WIF and BERA.

The tick size will be reduced for these markets to improve tradability and support increased volume.

From 6 October 2026, new orders that do not conform to the updated tick size will be rejected.

As all parameter changes are reductions, orders that conform to the current specifications will also conform to the new specifications automatically. The changes apply to all new and existing orders, while existing positions remain unaffected.

The updated specifications are available on the Linear Perpetuals KB page.


Deribit. Always Open.
