Pump.fun Transaction Stuck? How to Fix It (2026)
Updated January 2026 · SolBundler Team
Why Pump.fun Transactions Get Stuck in 2026
Stuck transactions on Pump.fun in 2026 are usually caused by: expired blockhash, insufficient priority fee, network congestion, or RPC node issues. Understanding the cause determines the fastest fix.
Expired Blockhash
Solana transactions include a recent blockhash that expires after approximately 60 seconds. If your transaction hasn't landed within that window, it's automatically rejected. Solution: resubmit with a fresh blockhash. SolBundler handles this automatically.
Insufficient Priority Fee
During high congestion, transactions with low priority fees sit in the queue indefinitely. In 2026, always check the current recommended priority fee on Solana before submitting. Use at least 0.001 SOL for standard transactions and 0.005+ for time-sensitive operations.
Network Congestion
Solana experiences periodic congestion spikes, especially during popular token launches or market volatility. During congestion, even high priority fees don't guarantee fast inclusion. Monitor solanabeach.io for network health.
RPC Node Issues
Free public RPC nodes are often overloaded and slow. If your transaction appears stuck, try switching to a premium RPC (Helius, QuickNode). SolBundler uses Helius RPC for maximum reliability.
How SolBundler Prevents Stuck Transactions
SolBundler automatically manages blockhash freshness, sets competitive priority fees, uses premium RPC, and submits to multiple Jito endpoints simultaneously. This multi-layered approach eliminates most stuck transaction scenarios for bundle launches.
