<summary>What if I do not get my tokens on the destination chain?</summary>

In very rare cases, the following might happen. If an error constantly occurs, please contact the zkJump team via email or in our discord channel.

**Case 1:** token stays on my wallet of the source chain, but the gas fee is deducted from my wallet.

* Reason: the transaction is failed but already committed on-chain.
* Root cause: blockchain error — it might be network congestion, wrong gas estimate, or transaction conflict.
* Solution: initiate the transaction again.

**Case 2:** token is deducted from my wallet on the source chain, but I didn’t receive the token on the target chain.

* Reason: Your transaction has been submitted successfully and is waiting for zkJump to be processed
* Root cause: zkJump congestion — It may be that the transaction is blocked or the Witness discovered the transaction anomaly and stopped all transactions.
* Solution: There is no risk to your assets, please wait for the Executor to initiate your transaction on the target chain.
