Deciphering Solana Transaction Issues

The Solana network experienced significant congestion in April, causing substantial delays and a high transaction failure rate. Reports indicate that over 70% of non-voting transactions had not been processed successfully.

Solana transaction failures typically arise from two main issues: execution failures and transaction drops. Execution failures occur when the network recognizes and processes the transaction but cannot complete it successfully. This results in the consumption of gas fees without achieving the desired result. Common causes include unmet preconditions such as interacting with an already sold-out mint function or encountering excessive slippage due to rapid price fluctuations that exceed set tolerance levels.
