You should first check the public blockchain for your transaction. If you cannot find confirmation, look to see if a miner’s fee was paid. If no fee was paid or a low fee was paid, there are two options depending on the type of wallet you have:
- Opt-in Replace-By-Fee (Opt-in RBF): This enables you to resend a transaction with a higher mining fee. The will incentivize the miner to confirm the transaction so it can complete.
- Child Pays for Parent (CPFP): With CPFP, transactions are thrown into pools of combined transactions. Rather than transactions being confirmed individually groups are confirmed based on the highest combined fees. Contact your wallet provider for more information on how this process works.
In the event neither of these options is available, you will likely have to wait for the transaction to confirm or the Bitcoins to be returned to your wallet. Up to the point a transaction is confirmed, Bitcoins are still in your virtual wallet even if they do not appear to be.
Many wallets return a transaction after 72 hours. We would advise you to contact your wallet for its specific return times.
