Why hasn't my transaction confirmed yet? – Blockchain Support Center

A "stuck" transaction is a transaction which has remained unconfirmed for period of time which either the receiver or the sender is uncomfortable with. Stuck transactions can be annoying as it means that recipients often consider the senders to not have paid yet, or the recipient needs the money as soon as possible. Stuck transactions are typically caused by low transaction fee rates.

However other things can cause stuck transactions such as spending from an unconfirmed transaction, having dust outputs in the transaction, or being a double spend of another transaction. If a transaction has a double spending transaction and the double spend confirms, then the transaction will be "stuck" forever as it can never confirm. If you are incapable of performing any of the other options or are too afraid to do so, you can simply wait and hope that the transaction will eventually confirm.

To ensure the network is constantly being reminded of the transaction, you can rebroadcast the transaction periodically. Most wallets will rebroadcast automatically, so simply leaving your wallet open will allow rebroadcasting to happen.

If a transaction remains unconfirmed for too long, it can be eventually "forgotten" by most nodes on the Bitcoin network if no one rebroadcasts the transaction. This happens due to node restarts, mempool expiry times, or mempool eviction because the minimum mempool fee has increased. This process typically takes a few days usually 3. Once a transaction has been "forgotten", you may not see it in your wallet and you probably will not see the transaction in most block explorers.

Once the transaction has been "forgotten", you can simply send the Bitcoin again but include a higher transaction fee. If you still see the transaction in your wallet but don't find it on any block explorers, you will need to follow the instructions in the next Replace-By-Fee Section. Note that some wallets will continuously rebroadcast the transaction while the wallet is on, so you either have to remove the transaction from the wallet using the instructions in the RBF section, or shut down the wallet and keep it off for several days.

Some mining pools and miners offer services to allow you to prioritize your transaction in their mempool so that it is chosen sooner for inclusion in a block. One such service is https: Another such service is https: Also note that if you attempt a Replace-By-Fee transaction, both the original transaction and the RBF transaction will be considered double spends.

Miners will likely not help with any transactions marked as double spends. A Replace-By-Fee transaction is a transaction that is nearly identical to your stuck transaction but pays a higher transaction fee.

Since the original transaction most likely does not use Opt-in RBF, the RBF transaction that we will be creating will be considered a double spend and marked as such. The transaction uses Full-RBF and thus may still take a little bit longer to confirm as it is technically a double spend.

Full RBF means that the transaction is simply a double spend of another transaction but pays a higher transaction fee than the one s it replaces. The instructions given in this section will be for making Full RBF transactions. Making a Full RBF transaction depends entirely on the wallet that you are using.

Some wallets support the advanced functionality required to make a Full RBF transaction, others do not. The following will be guides for each wallet on how to make a Full RBF transaction with that wallet. In general the procedure is to remove the unconfirmed transaction from the wallet and then resend the Bitcoin but with a higher transaction fee. When making a Full RBF transaction, the transaction should include the recommended fee rate effective at the time of creating the transaction.

See the "Avoiding this issue in the future" section for help with that. Simply go to the transactions list, right click the transaction that is stuck, and choose the Abandon Transaction option. If that option is greyed out, go to the Bitcoin Core datadir and delete the mempool. If the above two options fail for some reason, start Bitcoin Core with the -zapwallettxes option to clear all unconfirmed transactions from your wallet.

Once the transaction is either Abandoned or cleared from the wallet, you can simply go to the Send tab and send the Bitcoin again but make sure that you include a sufficient transaction fee. This will clear all of the unconfirmed transactions from the wallet and thus allow you to create the Full RBF transaction. Once Armory has restarted, simply send the Bitcoin again as you normally would but be sure to include a sufficient transaction fee.

Go to Manage Wallet and click on Repair Wallet and follow the wizard. This process will clear all of the unconfirmed transactions from your wallet much like Bitcoin Core and Armory do. Once repair wallet has completed, simply send the Bitcoin again as you normally would. Note that some users have had trouble with this method in the past and it may not always work. You may need to wait for the transaction to be "forgotten" in order for this method to work. Not all wallets support the creation of Full RBF transactions.

Many wallets do not allow clearing all unconfirmed transactions to allow for making Full RBF transactions. The following is a list of wallet software which do not support Full RBF transactions.

If a wallet on this list does support FullRBF transactions, please let me know and provide instructions for that so I can add it above. A Child-Pays-For-Parent CPFP transaction is exactly as the name implies, a child transaction spends from an unconfirmed parent transaction and includes a transaction fee which covers both the fee of the child and the parent. However creating CPFP transactions are much more difficult as it requires spending from an unconfirmed transaction, something that many wallets do not allow.

The best way to avoid having stuck transactions is to make sure that you are not spending from an unconfirmed transaction, and include a sufficient transaction fee. If your wallet supports dynamic transaction fees, you should use those. If you want very fast confirmations, set the dynamic fees to choose the fastest fee possible. Dynamic fees are calculated by the wallet by analyzing the current state of the network and determining an optimal transaction fee from there.

Since the state of the network constantly changes, the optimal transaction fee calculated one day may not necessarily be the best fee for the next day.

If your wallet does not support dynamic fees but does support setting a custom transaction fee rate for each transaction, you can look up the optimal fee rate on sites like http: You must do this for each transaction you make otherwise you may end up paying a sub-optimal fee. If your wallet does not support any sort of fee rate or does not allow setting custom transaction fees, you should upgrade to a new wallet. Using a fixed fee or fixed fee rate is no longer a good idea as the network constantly changes.

You can use this formula: Note that some wallets e. If you notice that your transactions are constantly being stuck even though you are using dynamic fees, you should check the settings of your wallet and perhaps even switch to a new wallet which has no limit to the transaction fee. Then when you want to send some Bitcoin, next to the Fee slider is a box labeled "Replaceable".

Check that box so that while the transaction is still unconfirmed you can replace the transaction with one that pays a higher fee. Mixing reinvented for your privacy Chip Mixer. Hero Member Offline Posts: All you can do is hope that a miner takes pity on your transaction and includes it. Or, you can offline your wallet, delete the transaction, wait until the rest of the network has forgotten it, then pop back up and use the rawtransaction API to redeem that input with some others back to your wallet.
