Pending transactions
Why is my Stacks transaction pending?
On L1 Stacks the average time between blocks is about 10 minutes. Transactions pending between 2 minutes and 60 minutes is not uncommon.
While there are no known issues impacting correct, well-formed transactions, some transactions can be pending for a long time. Pending transactions will be discarded after 256 blocks or ~48 hours — a transaction that is not confirmed, by definition, has no impact on your assets and can be re-sent by the original sender.
Transaction pending for several hours or longer? Contact wallet support and/or check for these common issues:
- 1.Check that the balance is sufficient for example if you are making a STX transfer, will there be enough left for the transaction fee (for the miner)?
- 2.Are the nonce is order without any gaps. An account that has not send any transactions yet sends the first transaction with a nonce of 0 then 1, 2, 3, 4, etc.
- 3.When the network is congested it can also take more time for transactions to get processed. You can check the amount of transactions waiting to be processed at these sites: Haystack Mempool Explorer or Stacksdata.info mempool graphs.
