# Bridge sUSDC,  sWETH, sWBTC

## sTokens Overview

**sTokens** (sUSDC, sUSDC.e, sWETH, sWBTC) are minted on the **Symbiosis chain** (the Symbiosis Host Chain) and are used within the Symbiosis protocol to enable cross‑chain operations. 

Users cannot trade sTokens directly, but they may receive them when adding or removing liquidity in **Symbiosis Octopools**.

If you have sTokens and don’t want to simply hold them, you have two options:

1. **Provide liquidity:**\
   Add your sTokens (sUSDC, sWETH, sWBTC, etc.) to a Symbiosis liquidity pool and earn rewards.\
   See [farming-on-octopools](https://docs.symbiosis.finance/reward-programs/farming-on-octopools "mention") for details.
2. **Bridge back to native tokens:**\
   sUSDC, sWETH, sWBTC, etc. can be bridged 1:1 to USDC, WETH, WBTC, and other supported tokens (see instructions below).

## **About gas on the Symbiosis chain**

The Symbiosis chain uses **SIS** as its native gas token (bridged from Ethereum). SIS can be obtained in two ways:

1. Via the official L2 bridge at <https://symbiosis.bridge.caldera.xyz/>
2. Via [Symbiosis WebApp](https://app.symbiosis.finance/swap?chainIn=Symbiosis\&chainOut=Symbiosis\&tokenIn=SIS\&tokenOut=SIS)

## Bridging sUSDC, sWETH, sWBTC, etc.

sUSDC, sWETH, sWBTC, etc. can be bridged 1:1 back to their native tokens (USDC, WETH, WBTC, etc.) on a corresponding networks.
