Always Set Compute Unit Limits

Never send a transaction without explicitly setting a compute unit limit. Without a CU limit, Solana defaults to a high maximum (1.4 million CUs for a single transaction), which inflates your effective cost and reduces your priority score. Always simulate first, then set your CU limit to actual usage plus a 10–20% buffer.

Use Dynamic Fee Estimation

Never hardcode a priority fee. Markets change rapidly—a fee that worked yesterday may be insufficient today. Implement fee estimation logic that queries the current fee market using getRecentPrioritizationFees or a dedicated fee API before every transaction. Cache results for 10–30 seconds to reduce API load while staying current.

Implement Retry with Fee Escalation

Always implement retry logic for important transactions. If a transaction hasn't been confirmed after 30–60 seconds, resend it (with a new blockhash) at a higher priority fee tier. Increase fees by 50–100% per retry attempt up to a reasonable maximum. Use preflight simulation to catch errors before spending fees on doomed transactions, and consider durable nonces for long-running operations.
