The 4 Main Causes of Slow Token Transactions
Before you can fix the problem, you need to pinpoint the cause. Here are the four most common culprits:
- Network Congestion: This is the #1 cause. When too many transactions flood the network (like during a major meme coin launch or NFT mint), validators get overloaded. Transactions queue up, and processing times soar from <1 second to 30+ seconds.
- Poor RPC Configuration: Your connection to the blockchain matters. Using a public, rate-limited RPC endpoint guarantees slowdowns during peak times. A private or dedicated RPC can mean the difference between instant failure and reliable execution.
- Insufficient Priority Fees: On networks like Solana, you can add a small extra fee (a priority fee) to jump the queue. Not using this, or setting it too low, leaves your transactions stuck behind others who paid more.
- Inefficient Transaction Construction: Sending dozens of small, individual transactions instead of bundling them into one batch creates unnecessary on-chain load. This is a common mistake for airdrops or reward distributions.
