F.A.Q.

1. How does slippage tolerance work for Crosschain swaps?

For Crosschain swaps, your selected slippage tolerance percentage is applied independently to swaps on both the source and destination chains.

Example:

• Swap POL on Polygon to ETH on Ethereum

• Slippage tolerance set to 1%

• The route could be:

  1. Swap POL to USDC on Polygon

  2. Bridge USDC from Polygon to Ethereum via AcrossV4

  3. Swap USDC to ETH on Ethereum

• In this case, the 1% slippage tolerance applies separately to:

  • The swap on Polygon

  • The swap on Ethereum

This ensures you’re protected from excessive price movements on both legs of the transaction while keeping the bridging process itself unaffected by slippage settings.

2. What happens if my transaction fails?

If your Crosschain swap encounters a failure at any stage, here’s how it’s handled:

1. Swap/Transaction Failure on Source Chain

   ➝ You’ll instantly receive your original token back on the source chain.

2. Bridge Transaction Failure

   ➝ The time it takes for tokens to be refunded depends on which router was used to process the transaction. It usually takes a couple of minutes, but it can take up to a couple of hours.

3. Swap Failure on Destination Chain

   ➝ You’ll receive the bridged asset on the destination chain, without the final swap to your target token.

3. Can I swap stablecoins between chains?

Yes — you can swap and bridge stablecoins like USDC, USDT, and DAI directly between any supported chains.

You have two options:

1. Direct Bridge:

   Bridge supported stablecoins (like USDC, USDT, etc) directly from one chain to another.

2. Swap to Other Tokens:

   You can also swap a stablecoin to any other token supported on the destination chain using PancakeSwap’s liquidity pools — either before or after bridging.

4. Is there a minimum or maximum limit on swap amount?

Yes — both minimum and maximum limits apply to cross-chain swap transactions.

• Maximum Limit: Depends on the available bridge liquidity for the selected token and chain. This value can fluctuate in real-time based on network and liquidity conditions.

• Minimum Limit: Set to ensure it’s economically viable for relayers to process the bridge transaction.

Note: The exact min and max limits vary by bridge token. If your transaction amount is outside the allowed range, the interface will show a clear error message and prompt you to adjust the amount.

5. Are my Crosschain swaps MEV protected?

It depends on which router the transaction will go through when executed. MEV protection is usually enabled in most routers.
