# Provide Liquidity to Symbiosis Octopools
## Symbiosis Octopools Overview
Symbiosis uses **Octopools** for cross-chain operations. Each cross-chain transaction goes through an Octopool located on the **Symbiosis chain**, also referred to as the **Symbiosis Host Chain**.
An Octopool is a multi-token pool. There are three main Octopools:
* With stable coins (USDC, USDT, etc.) bridged from supported chain,
* With wETH tokens bridged from supported chain,
* With wBTC bridged from supported chains
The easiest way to view supported tokens and chains is through the [**Pools**](https://app.symbiosis.finance/liquidity-v2/pools) section in the Symbiosis WebApp:
* **Token:** the token available for liquidity provision.
* **Chain:** the chain from which the token can be supplied.
* **Total Locked:** total tokens locked in the pool.
* **Pool Balance:** current balance ratio for this token in the pool. It affects deposits, withdrawals, and route availability.
* **APR:** annual percentage rate for liquidity provision.
## How Liquidity Is Added
Symbiosis Octopools are located on the **Symbiosis chain**. Because of this, when liquidity is supplied from another blockchain, the token first needs to be moved to the Symbiosis chain and then added to the pool.
In the standard WebApp flow, this is done in one deposit operation:
1. The source token is locked in a dedicated contract on the source network.
2. The bridged token is minted on the Symbiosis chain.
3. The token is added to the Octopool.
4. LP tokens are issued on the Symbiosis chain.
Advanced users can also do this manually in two steps: bridge the token to the Symbiosis chain first, then add it to the pool.
## Address for LP tokens
When liquidity is added, LP tokens are issued. These tokens are required to withdraw your assets, so make sure they are sent to an address you control.
If you add liquidity from an **EVM EOA wallet**, LP tokens are sent by default to the same EVM-compatible address on the Symbiosis chain.
If you add liquidity from a **non-EVM network**, such as Solana or TON, provide an **EVM-compatible address** on the Symbiosis chain to receive LP tokens.
If you use a **multisig contract** or another smart contract wallet, make sure to set a valid LP token receiver address on the Symbiosis chain. Contract addresses may differ between the source network and the Symbiosis chain.
To set a custom LP token receiver address, enable the receiver address switch in the WebApp and enter an address you control.
## Depositing Liquidity
To deposit liquidity to a Symbiosis Octopool:
1. Go to [Symbiosis WebApp > the *Pools* tab](https://app.symbiosis.finance/liquidity-v2/pools).
2. Connect your wallet.
3. Find the token and chain you want to supply liquidity for, then press **Manage** (for example, WETH on Arbitrum One):\
4. Enter the amount to deposit:\
\
\
**Important:**\
If a **multisig contract** is used to sign transactions, provide a valid address on the Symbiosis chain for receiving LP tokens. Multisig contract addresses often differ between the source blockchain (where liquidity is sent from) and the destination blockchain (the Symbiosis chain).\
\
To set a custom LP token address, enable the switch in the WebApp and enter a valid address you control:\
5. If prompted, press *Switch network to \* and confirm in your wallet.
6. If prompted, press *Approve \* button and confirm in your wallet.
7. Review the details, then press *Add liquidity* and confirm in your wallet.
8. Wait for confirmation — liquidity is added to the pool.
9. To check, go to [Symbiosis WebApp > the *Pools* tab > My Liquidity](https://app.symbiosis.finance/liquidity-v2) to view your deposits:\
Done \
\&#xNAN;**∎**
## Withdrawing Liquidity
Symbiosis Octopools are hosted on the **Symbiosis chain**. Liquidity can be withdrawn only on this chain.
**About gas on the Symbiosis chain:**
The network uses **SIS** as its native gas token (bridged from Ethereum). SIS can be obtained in two ways:
1. Via the official L2 bridge at
2. Via [Symbiosis WebApp](https://app.symbiosis.finance/swap?chainIn=Symbiosis\&chainOut=Symbiosis\&tokenIn=SIS\&tokenOut=SIS)
### Withdrawal Process
Liquidity withdrawal has two steps:
1. **Remove liquidity** from the pool.
2. **Bridge sTokens** (e.g., sUSDC, sWETH, sWBTC) into the corresponding native assets (USDC, WETH, WBTC, etc.). Do not miss the instructions below: [#bridging-susdc-sweth-swbtc-etc](#bridging-susdc-sweth-swbtc-etc "mention")
### Removing Liquidity
To withdraw liquidity from Symbiosis Octopool:
1. Go to [Symbiosis WebApp > the *Pools* tab > My Liquidity](https://app.symbiosis.finance/liquidity-v2):\
2. Press *Manage* for the asset you want to withdraw.
3. Press *Remove*:\
4. Select the amount to withdraw (e.g. 75%):\
5. If prompted, press *Switch network to \* and confirm in your wallet.
6. Press *Remove* and confirm in your wallet.
7. Wait for confirmation — liquidity is removed from the pool.
**Note:**\
When liquidity is withdrawn, you receive **sTokens** (e.g., sUSDC, sWETH, sWBTC) on the **Symbiosis** chain.\
These can be bridged 1:1 to their native tokens (USDC, WETH, WBTC, etc.).\
See instructions below for bridging.
Done \
\&#xNAN;**∎**
### Bridging sUSDC, sWETH, sWBTC, etc.
When liquidity is withdrawn from Octopools, you receive **sTokens** (sUSDC, sWETH, sWBTC, etc.) on the **Symbiosis chain**. These sTokens can be bridged 1:1 back to their native tokens (USDC, WETH, WBTC, etc.) on your target network.
To bridge sTokens:
1. Go to the **Bridge** section in Symbiosis WebApp: \
\
**Important:** \
The **Bridge** section is different from the **Swap (Exchange)** section \
2. Connect your wallet.
3. In *Transfer From*, select the **Symbiosis chain** and choose the sToken to bridge (e.g., sWETH).\
4. In *Transfer To*, select the destination token (only one option is available for each sToken type, e.g., sWETH → WETH on Arbitrum One).\
5. Enter the amount to bridge:\
6. Press *Burn*, then confirm the transaction in your wallet.
7. Wait for confirmation — the tekens are bridged to the destination network.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.symbiosis.finance/user-guide-webapp/octopool-provide-liquidity.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
