# Turbo and Stable

Built on top of our classic QUEEN-BISHOP-ROOK structure, the Turbo & Stable series is customized for points earning and rewards. Get the most out of your points-earning assets with Turbo & Stable, even if you are just here for fixed-interest earning.

Specifically:

* [**QUEEN**](/faq/turbo-and-stable/queen.md): The QUEEN token swaps 1:1 with the underlying assets from day one till the fund reaches maturity. The ratio will always stay at 1:1.
* [**Turbo**](/faq/turbo-and-stable/turbo.md): An enhanced version of ROOK, customized for maximum points earning. Leverage the leverage for points earnings at a cost.
* [**Stable**](/faq/turbo-and-stable/stable.md): Enhanced BISHOP. Fixed and competitive interest earning with no lock-up period.

Tranchess Turbo and Stable structure for points-earning are now on Scroll and BNB Chain.
