In this document, you’ll find solutions to common issues, explanations of key aspects, and helpful tips for locating your tokens:
If you’ve exchanged tokens on the same blockchain, you can track the transaction using the block explorer for that blockchain (e.g., Etherscan for Ethereum).
If you've exchanged tokens across different blockchains.
For example: you exchanged ETH from Ethereum for USDC on zkSync ERA. To track such an operation, use the .
About Symbiosis Explorer
Symbiosis Explorer collects and analyzes data from cross-chain operations performed via the Symbiosis protocol across all supported networks. It provides a detailed status of each operation, helping you track your transactions.
The "Stuck" status on a cross-chain swap indicates that the operation is taking longer than usual but is still likely to be completed.
However, if the operation cannot be completed, it will be reverted automatically or manually, depending on when it was initiated:
After February 9, 2025: Cross-chain swaps labeled "Stuck" are automatically reverted within 12 hours.
Before February 8, 2025: You will need to manually revert the swap by following this guide: Stuck Transactions
There’s no magic involved — all swap details are displayed in the Symbiosis WebApp interface before you confirm the transaction in your wallet. Once you sign the transaction, no changes can be made. In most cases, the amount of tokens you receive matches the calculation shown in the Symbiosis WebApp.
What to Consider Before Performing a Swap:
Slippage Tolerance
The number of tokens shown as "to receive" includes all liquidity provider fees and cross-chain fees.
Tip: Keep in mind that the actual amount of received tokens might differ slightly but will remain within the range set by your slippage tolerance.
Example: If 1,000 tokens are shown as "to receive" and your slippage tolerance is set to 3%, the actual amount received could range between 970 and 1,000 tokens.
For more information, see More about Slippage Tolerance
Cross-Chain Fees
When swapping to a blockchain network with high transaction fees (e.g., Ethereum or Tron), cross-chain fees can significantly impact the number of tokens you receive — especially for small swap amounts.
Swap size
The size of your swap can greatly affect the number of tokens received due to liquidity constraints and fees.
For more information on how cross-chain fees are calculated and deducted, please refer to Symbiosis & Fees
In rare cases, you may receive stablecoins (USDC, USDT), WETH, or WBTC on the destination network, even if you selected a different token as the destination token.
Why Does This Happen?
Cross-chain swaps involve exchanging assets between different blockchains, and these operations are not instantaneous. If the exchange rate on the destination network changes during the processing time and the new conditions no longer meet the stated ones, the Symbiosis protocol will deliver a stablecoin, WETH, or WBTC instead of the originally selected token.
Why stablecoins, WETH, or WBTC tokens?
Stablecoins, WETH and WBTC tokens have the same face value across different networks, making them ideal transit tokens for routing cross-chain operations within the Symbiosis protocol.
Previous Approach vs. Current Approach
Old Flow: Stuck Cross-Chain Operations Previously, if the exchange rate on the destination network changed and the swap couldn’t meet the stated conditions:
The operation was halted and the user had to send an additional transaction to revert the funds.
Tokens were refunded on the source network, meaning: users received tokens back on the source chain. Transaction and cross-chain fees were spent, even though the operation wasn’t completed.
Current Flow: Guaranteed Tokens on the Destination Network To improve user experience, Symbiosis introduced a new approach: if the swap cannot meet the stated conditions due to rate changes, then stablecoins, WETH, or WBTC are delivered directly to the destination network. This eliminates the need for users to send additional transactions or pay extra fees to recover their funds.
The Symbiosis protocol uses sTokens (e.g., sUSDC, sUSDC.e, sWETH, sWBTC) to perform cross-chain operations. While end-users cannot trade sTokens, they may receive them when adding or removing liquidity from Symbiosis Octopools.
What Can You Do with sTokens?
Provide Liquidity and Earn Rewards You can add your sTokens (sUSDC, sUSDC.e, sWETH, sWBTC) to a Symbiosis liquidity pool and earn rewards for providing liquidity. For more information, see the Farming on Octopools guide.
Remember, never share your pass phrases, private keys or any other sensitive information with anyone.
Type of operation: Bridging, exchange, liquidity withdrawal, etc.

If you prefer to retrieve your tokens: The option to undo the swap will become available 10 minutes after the "Stuck" status is assigned. Please use of the Symbiosis WebApp to revert stuck swaps. If you need more comprehensive guide, check Stuck Transactions for guidelines.
Example: Let’s consider a cross-chain swap from BNB Chain to Ethereum. The difference in fees is noticeable:
Tip: Always keep an eye on the price impact and the token amounts to send and receive, especially in their USD equivalents, to ensure the swap remains profitable:
Bridge sTokens to Their Equivalent Assets You can bridge sTokens (sUSDC, sUSDC.e, sWETH, sWBTC) 1:1 for their equivalent assets (USDC, USDC.e, WETH, WBTC) via . For a detailed step-by-step guide, please refer to this guideline: Bridge with Symbiosis: sUSDC, sWETH, sWBTC
