If your transaction is stuck as pending, it usually means it hasn’t been confirmed by the network yet. This is more common on Ethereum, Base, and Polygon, which process transactions differently from Solana or Sui.
How Ethereum, Base, and Polygon process transactions
These chains use a mempool, which is a queue of pending transactions. Miners or validators prioritize transactions that offer higher gas fees.
If you choose a low gas fee, especially during busy times, your transaction might sit in the mempool for a while, or not be processed at all.
Even if you have enough ETH or POL to cover basic fees, the transaction might still be delayed if the fee is set too low.
What you can do
If your transaction is pending for too long:
- Speed it up: Resubmit it with a higher gas fee. See Speed up a transaction by increasing gas fee.
- Cancel it: If you no longer want it to go through. See Cancel a pending EVM transaction.
How Sui processes transactions
Sui doesn’t use a mempool or gas auction system. Transactions are processed in parallel and ordered deterministically. You won’t typically see long pending times.
If a Sui transaction appears stuck:
- Refresh your wallet.
- Make sure you have enough SUI to cover gas. Minimum recommended: 0.01 SUI.
- Try resubmitting the transaction.
