# Sirius token (SIRS)

When liquidity providers contribute to the **Sirius DEX** (formerly known as Liquidity Baking), they receive a Sirius (SIRS) token as proof of their position in the XTZ-tzBTC liquidity pool. While receiving a liquidity token is standard for decentralized exchanges, the **SIRS** token goes beyond this, embodying a unique financial structure within the Tezos ecosystem.

**Sirius (SIRS)** is not just a representation of liquidity—it is a powerful financial instrument with a distinct value proposition:

* **Represents DEX Liquidity:** SIRS reflects the combined value of the Tez (XTZ) and Bitcoin (tzBTC) held in the liquidity pool.
* **Generates Revenue from Trading Fees:** Holders of SIRS earn a share of the transaction fees from the constant trading activity within the pool, directly benefiting from its usage.
* **Earns Tez (XTZ) Subsidy Rewards:** With each block, the Tezos protocol contributes newly minted XTZ to the pool as a subsidy, adding consistent yield to the liquidity providers

The **SIRS token** is more than just a symbol of participation—it is a dynamic asset that combines value representation, yield generation, and the ability to leverage liquidity in the rapidly evolving Tezos DeFi landscape.
