# Bridge SIS Token ## SIS Token Overview SIS serves as the governance token for the Symbiosis protocol, boasting key functions such as:
Governance SIS token holders have the privilege of participating in decision-making processes, especially concerning the Symbiosis DAO.Details →/pages/N4YkDu1G3N8ANDuoES6K
Protocol Security The SIS token is staked to operate relayers, ensuring the seamless functioning of the Symbiosis relayers network.Details →/pages/-MbqnR8ol3fmRhDBEAIN
Incentivization Active participation in protocol activities is rewarded with SIS tokens as incentives.Details →/pages/py6fYgMG0m8pjHMKu8Dc
Moreover, token holders are free to trade, exchange, or stake their SIS tokens. ## SIS Supported Blockchains SIS token was originally deployed on Ethereum (L1) and can bridged to the following L1 and L2 blockchain networks: * L2s: Arbitrum One, zkSync Era, Linea, Scroll, and the Symbiosis chain; * L1: the BNB Chain. ### SIS Token Contract Addresses (Adding SIS Token to a Wallet's Token List) Before using SIS tokens, ensure they're added SIS token to your wallet's token list for the specific blockchain networks you'll be working on.
How to add SIS token to a wallet's token list Adding a custom token to a wallet's token list usually involves manually inputting the token's contract address and other details. Here's a general step-by-step process for most wallets: 1. **Open Your Wallet App**. 2. **Access the Token List**: Most wallets have a section where you can see a list of tokens. It could be labeled as "Tokens", "Assets", "Coin Management", or something similar. 3. **Add Custom Token Option**: Look for an "Add", "+", or "Manage Tokens" option. Once you click on it, there might be an option to "Add Custom Token" or "Add Token Manually". 4. **Enter Token Details**: Here you'll typically need: * **Token Contract Address**: This is the unique address that represents the token on the blockchain. Make sure you copy it correctly and from a trusted source to avoid scams. * **Token Symbol**: This is the shorthand symbol for the token (e.g., ETH for Ethereum, BTC for Bitcoin). * **Decimals**: Most tokens use 18 decimals, but you should verify the exact number for your specific token. 5. **Confirm**: After entering the details, there should be a button to finalize the addition, something like "Add", "Confirm", or "Done". 6. **Verify**: Once added, go back to your token list and ensure the custom token is now visible with its proper details. 7. **Warning**: Always ensure you're adding the correct token. There are many scam tokens that might have similar names to legitimate ones. Always use trusted sources to get the contract address and other details. Different wallets might have variations in the process, but this is the general approach. Always refer to the specific instructions provided by your wallet provider or their official documentation

The original asset is typically locked on the source network and then represented (or minted) on the destination network. Bridging is always a cross-chain operation. SIS tokens can be bridged form Ethereum to Arbitrum One, zkSync Era, Linea, and Scroll using official bridges of these L2 networks, and SIS tokens can be bridged from Ethereum to the BNB chain using the Symbiosis bridge.

### Moving SIS Over Supported Chains {% hint style="info" %} Please use the official bridges listed above to move large amounts of SIS tokens {% endhint %} To swap SIS tokens across supported chains: 1. Navigate to the [Symbiosis WebApp](https://app.symbiosis.finance/swap). 2. Connect your wallet. 3. In the **Transfer from** field, select SIS token on Ethereum as the source token, and enter the amount you want to bridge to the BNB chain: 4. Select SIS token and chains in the **From** and **To** fields:\ ![](/files/oRPZPyDSNKtleiXBzlGw) 5. If you see the **Switch network to...** button, switch to the network by pressing the button and confirming the action in your connected wallet. 6. If you see the **Approve SIS** button, approve the token use by pressing the button and confirming the transaction in your wallet. 7. Press the **Swap** button, and confirm the transaction in your wallet.\ (You can close the window and check the transaction later) 8. Shortly, you will get a confirmation. ## Support {% hint style="warning" %} **Remember, never share your pass phrases or any other sensitive information with anyone.** {% endhint %} If you have any questions, please contact [our support team on Discord](). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
