Frequently Asked Questions

What causes the Blockhash Not Found error in Phantom wallet?
This error occurs when your transaction takes too long to process and the blockhash (a time-sensitive reference point on the blockchain) expires before submission. Network congestion and poor internet connectivity are common causes.
Will I lose my cryptocurrency if I get a Blockhash Not Found error?
No, your cryptocurrency is safe. This error occurs before the transaction is actually submitted to the blockchain, so no funds are transferred or lost. You can safely retry the transaction.
How long should I wait before retrying a failed transaction?
Wait 5-10 minutes before retrying to allow network congestion to clear. If you're still getting errors, try waiting during off-peak hours when the blockchain network typically has lower traffic.
Can increasing transaction fees prevent Blockhash Not Found errors?
Yes, higher transaction fees can help prevent this error by prioritizing your transaction for faster processing, reducing the chance that the blockhash expires before submission.
Is the Blockhash Not Found error specific to certain cryptocurrencies?
This error is most common on the Solana blockchain, which Phantom wallet primarily supports. Other blockchain networks may have similar timing-related errors but with different names.
