Swap Tokens

General walkthrough: How to swap tokens across supported blockchains using the Symbiosis WebApp

Steps to Perform a Cross-Chain Swap

Symbiosis WebApp is available at https://app.symbiosis.finance/

Before you start: Make sure you have enough native tokens (gas) on the source network to pay transaction fees.

1. Select your From and To tokens and chains.

2. Enter the amount of tokens you want to swap (From).

3. Review swap details: Do not skip this step Symbiosis automatically finds the best route for your selected token pair and amount. Always review the output before confirming the swap. Key values to check:

   1. The estimated amount to receive (1)

   2. USD values (2)

   3. Minimum received (4)

   Swap details complete explanation:

(1) To amount: Estimated amount to be received on the destination network. The final amount may vary slightly due to slippage, but it will not be lower than the Minimum received amount (4).

(2) USD values: Approximate USD value of the selected amounts. Useful for comparison.

(3.1) Receive to another wallet: The recipient address can be either taken from the connected wallet or entered manually. If an address is entered, it must be confirmed in (3.2)

(4) Minimum received: The minimum guaranteed amount you will receive after the swap, based on current rates and settings.

(5) Other swap details:

• Price: Current conversion rate for your swap, influenced by trade size.

• Slippage Tolerance: Percentage of the trade value you’re willing to accept as a price change. It can be adjusted via the settings icon.

• Estimated time: Expected time to complete the cross-chain swap, based on historical data.

• Price impact: How much this swap affects the market price.

• Discount: veSIS holders are eligible for discounts on protocol fees for certain chains.

• Fee: Total estimated fee for the swap. This excludes the transaction fee on the source chain.

1. Connect wallet & switch network Connect your wallet and switch to the required source network when prompted.

2. Approve token (if needed)

   1. Native tokens (ETH, BNB, etc.) do not require approval.

   2. Non-native tokens (USDC, USDT, etc.) require Approve.

   Approval gives Symbiosis permission to use the selected token for the swap.

3. Confirm the swap Click Swap and confirm the transaction in your wallet.

4. Wait for completion Cross-chain swaps usually take 1–3 minutes. Swaps involving the Bitcoin network may take longer.

5. Track your swap You can track the status and history of your swaps using Symbiosis Explorer.

2. Locate the token you want to add to your favorites, click the ... button next to the token and select Add to favorites:

Swap Routing and Liquidity Sources

Symbiosis supports both cross-chain and on-chain swaps. Depending on the route, a swap may use Symbiosis infrastructure together with external liquidity sources, such as DEXs, pools, aggregators, or partner protocols.

In the Symbiosis WebApp, users can manage available liquidity sources in settings:

Important: Disabling a source may remove some available routes or reduce the number of routing options for certain swaps. Here is an example:
