# SIS Token Guide

## Overview

SIS is the governance and utility token of the Symbiosis protocol.

It is used for governance, relayer staking, protocol incentives, and as the gas token on the Symbiosis chain. SIS holders can trade, transfer, or stake their tokens where supported.

This guide explains where SIS is available and lists the addresses of the relevant token contracts. It also explains how to transfer SIS between supported networks and swap it for other tokens.

## Supported Chains and Addresses

{% hint style="warning" %}
Always check the network before adding, sending, or bridging SIS.

SIS contract addresses are different on each network. Using the wrong network or contract address may result in loss of funds. Copy addresses only from this page or from the linked block explorer.
{% endhint %}

SIS was originally deployed on Ethereum and later bridged to other networks. 

SIS is currently available on the following networks:

## Add SIS to Your Wallet

If SIS is not shown in your wallet, add it as a custom token.

When adding SIS manually, make sure the selected wallet network matches the SIS contract address you use.

Use the SIS contract address for the selected network. Most wallets also ask for the token symbol and decimals. If these fields are not filled automatically, check the linked block explorer for the correct token details.

For Symbiosis chain, SIS is the native gas token, so it may be displayed as the network’s native asset rather than as a custom token.

## Get SIS

You can use [Symbiosis WebApp](https://app.symbiosis.finance/swap) to swap tokens for SIS:

1. In the **From** field, select the source chain and the token you have. In the **To** field, select the destination chain and the SIS token.
2. Enter token amount.
3. Check swap details:\
   ![](/files/JyAwaPIDLKXOcIziufJg)
4. Connect your wallet and confirm the swap.

## Move SIS Across Supported Chains (SIS <> SIS)

The most convenient way to move SIS tokens between supported networks is to use [Symbiosis WebApp](https://app.symbiosis.finance/swap)

1. In the **From** field, select the source chain and SIS. In the **To** field, select the destination chain and SIS.
2. Enter token amount:\
   ![](/files/3x8BR3LIt09QVHXkNoPL)
3. Connect your wallet and confirm the swap.

**Important:** If you are moving a large amount of SIS tokens and the Symbiosis WebApp shows unfavourable rates for your swap, use the official bridges to move your SIS tokens.

**Example:** If you move SIS tokens from Arbitrum One to BNB chain using official bridges, then:

1. Bridge SIS tokens from Arbitrum One to Ethereum using [Arbitrum Official Bridge](https://bridge.arbitrum.io/)
2. Bridge SIS tokens from Ethereum to BNB chain using [Symbiosis Bridge](https://app.symbiosis.finance/bridge?chainIn=Ethereum\&chainOut=BNB\&tokenIn=0xd38BB40815d2B0c2d2c866e0c72c5728ffC76dd9\&tokenOut=0xF98b660AdF2ed7d9d9D9dAACC2fb0CAce4F21835)
