Quickstart

Decode your first failed transaction in under 60 seconds.

Follow these steps to diagnose a failed Soroban transaction using the Prism CLI.

1. Identify a failed transaction

   Find a transaction hash (tx_hash) that failed with a cryptic error like Error(Contract, #3).

2. Run the decode command

   Terminal

   prism decode abc123def456... --network testnet
   
3. Review the diagnostic report

   Prism will resolve the error and provide a clear explanation.

   Diagnostic Report:
   ------------------
   Error: InsufficientBalance (resolved from #3)
   Contract: CD...123 (MyTokenContract)
   Reason: The sender does not have enough XLM to complete the transfer.
   Suggested Fix: Ensure the account has at least 10 XLM before retrying.
