❓FAQ

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 BNB on BNB Chain to ARB on Arbitrum

• Slippage tolerance set to 1%

• The route could be:

  1. Swap BNB to USDC on BNB Chain

  2. Bridge USDC from BNB Chain to Arbitrum via Across

  3. Swap USDC to ARB on Arbitrum

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

  • The swap on BNB Chain

  • The swap on Arbitrum

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

   ➝ Across will process a refund within 90 minutes to 2 hours, and you’ll receive the bridged asset back on the source chain.

3. Swap Failure on Destination Chain

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

Note: You can always check the status of your transactions through the transaction history tab under wallet connect UI.

3. Are my Crosschain swaps MEV protected?

MEV Guard is only supported on the BNB Chain when swaps are initiated directly from a connected wallet with MEV Guard enabled.

• If your Crosschain swap involves a swap on BNB Chain as the source chain, and you have MEV Guard enabled, that swap will be MEV protected.

• If BNB Chain is the destination chain, the swap is executed by the bridging relayer/system and will not be MEV protected, since it’s not initiated by your connected wallet.

Note: Other chains like Arbitrum and Base currently do not support MEV Guard protection on PancakeSwap.

4. 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.

Note: Supported stablecoins for direct bridging may vary by chain.

5. Will my swaps use PCSX?

No — PCSX is not supported for servicing Crosschain swaps.

Crosschain swaps on PancakeSwap are exclusively routed through:

• PancakeSwap’s liquidity pools (v2, v3, Infinity, StableSwap) for on-chain swaps, and

• Across protocol for bridging assets between chains.

PCSX cannot be used to facilitate or route any part of a Crosschain swap transaction.

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

Yes — both minimum and maximum limits apply to Crosschain 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.
