How to bridge synthetic assets (sUSDC, sWETH, sWBTC) using the Symbiosis WebApp.
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:
Provide liquidity:
Add your sTokens (sUSDC, sWETH, sWBTC, etc.) to a Symbiosis liquidity pool and earn rewards.
See Farming on Octopools for details.
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:
sUSDC, sWETH, sWBTC, etc. can be bridged 1:1 back to their native tokens (USDC, WETH, WBTC, etc.) on a corresponding networks.
Go to the Mint and Burn section in Symbiosis WebApp: https://app.symbiosis.finance/bridgeImportant:
The Mint and Burn section is different from the Swap section:
Connect your wallet.
In the From field, choose the sToken to bridge (e.g., sWETH):
In the To field, select the destination token (only one option is available for each sToken type, e.g., sWETH → WETH on Arbitrum One).
Enter the amount to bridge:
Switch to the Symbiosis chain: click the Switch network to Symbiosis button.
Press Burn, then confirm the transaction in your wallet.
Wait for confirmation: the tekens are bridged to the destination network.
You can always check status of your cross-chain operations in Symbiosis Explorer.
