🔍 Use these columns to gather comprehensive insights into failed transactions on the Solana blockchain, identifying the context of failures along with diagnostic details. Examine when they occurred, their cost in both lamports and USD, their exact position in the chain, among other key metrics. You can:

* Identify the block and transaction context using <kbd>BLOCK\_SLOT,</kbd> <kbd>TIMESTAMP</kbd>, <kbd>DATETIME</kbd>, <kbd>BLOCK\_HASH</kbd>, <kbd>BLOCK\_HEIGHT</kbd>, <kbd>TRANSACTION\_INDEX</kbd>, and <kbd>TRANSACTION\_ID</kbd>.
* Analyze fee-related information using <kbd>SOURCE\_TRANSACTION\_FEE</kbd>, <kbd>TRANSACTION\_FEE</kbd>, and <kbd>USD\_TRANSACTION\_FEE</kbd>.
* Evaluate network performance with <kbd>COMPUTE\_UNITS\_CONSUMED</kbd>.
* Retrieve error details via <kbd>ERROR</kbd>.
* Confirm transaction authenticity with <kbd>RECENT\_BLOCK\_HASH</kbd>.
* Review signature data through <kbd>SIGNATURES</kbd>, <kbd>SIGNER</kbd>, and <kbd>SIGNERS</kbd>.
* Access additional account information via A<kbd>CCOUNT\_KEYS</kbd> and <kbd>ADDRESS\_TABLE\_LOOKUPS</kbd>.
* Inspect diagnostic outputs with <kbd>LOG\_MESSAGES</kbd>, <kbd>VERSION</kbd>, <kbd>RETURN\_DATA</kbd>, and <kbd>STATUS</kbd>.
* Monitor data recency using <kbd>DATE\_CREATED</kbd> and <kbd>DATE\_UPDATED</kbd>.

💡 For example, you might query <kbd>ERROR</kbd>, <kbd>USD\_TRANSACTION\_FEE</kbd>, and <kbd>SIGNERS</kbd> to understand why a transaction failed and assess its fee cost, along with other key parameters.
