Causes and fixes
| Failure | What happened | What to do |
|---|---|---|
| Slippage exceeded | Price moved past your tolerance before landing | Raise slippage or use Auto |
| Blockhash expired | Congestion outlived the transaction’s validity | Retry with a higher priority fee |
| Insufficient SOL | Amount plus fees exceeded your balance | Leave headroom for network fees |
| Pool state changed | Liquidity pulled or curve completed mid-flight | Re-check the token before retrying |
| Protected lane full | Anti-MEV mode could not land it safely | Retry; the terminal never falls back to the public mempool for you |
