Here Is How You Can Accelerate Stuck Bitcoin Transactions
Check the fee: Before you start trying to accelerate your transaction, check if the fee you have set is too low. If so, increase the fee and try again.
Use a different wallet: Some wallets have better support for accelerating stuck transactions. Try using a different wallet, such as Electrum or Mycelium, to see if it helps.
Use a different node: Some nodes may be clogged or slow, causing transactions to get stuck. Try connecting to a different node to see if it helps.
Wait it out: Bitcoin transactions can sometimes take several hours to complete. If it has only been a short time, simply wait and see if the transaction will go through.
Try a double spend: If your transaction is stuck, you can try double spending it by creating a new transaction with a higher fee and the same inputs.
Use a replacement service: There are several services that can help you accelerate your stuck transaction for a fee, such as ViaBTC or BTC.com.
Use RBF (replace-by-fee): If your wallet supports replace-by-fee, you can use this feature to increase the fee on your stuck transaction and have it confirmed faster.
Use CPFP (child pays for parent): If your wallet supports child pays for parent, you can use this feature to increase the fee on a parent transaction and have it confirmed faster.
Try a new transaction: If none of the above methods work, try sending a new transaction with a higher fee and the same inputs.
Contact the receiver: If the receiver of the transaction has control over a miner, they may be able to help speed up the confirmation of the transaction.
Use a block explorer: Check your transaction on a block explorer, such as Blockchair or Blockcypher, to see if it has been confirmed.
