Frequently Asked Questions (FAQ)

Please remember that the free service is simply rebroadcasting your transaction. This is like reminding miners that your transaction is waiting for them. If you used an extremely low fee, you may still have to wait until the network is less busy. If you used our Premium service, then we guarantee that your transaction will be accelerated and confirmed within 24hrs…usually a lot less.

When you send bitcoin, your wallet or other application broadcasts the transaction to the blockchain and you normally have to wait for some time before your transaction is ‘confirmed’ by a miner. Before this happens however, your transaction is added to a queue where miners can select the transaction that will be added to the next block they mine. This queue is called the mempool. If you used a low fee when sending your transaction, you will have to wait longer because your transaction is less profitable to mine than others.

If you’re in no hurry, then this can be ok if you don’t mind waiting. However in some cases, you may find you are waiting for longer than you’d hoped and your transaction can actually be ‘dropped’. When this happens, BTC Nitro can help by rebroadcasting your transaction across the blockchain, or by adding it to our partner mining pools for a fee

The simple answer here is that your transaction isn’t on the blockchain. This could be because when you sent a transaction and your computer/wallet/application didn’t have internet access or, there was some application error that caused the transaction to be sent in the wrong way. When a properly functioning wallet with access to the blockchain sends a transaction, it will appear on the blockchain (in the mempool) within a few seconds. Until it appears on the blockchain, there is nothing you can do to accelerate your transaction.

Sometimes, no miner will select your transaction from the mempool (especially when average fees are high and the blockchain is busy). This could happen for example if you sent your transaction with zero miner fee. Eventually, the transaction will timeout, will be dropped from the blockchain and your bitcoin will be returned to the senders wallet. Please be aware that this could sometimes take between 2 and 4 weeks – and we’re not able to speed up that process because we don’t own the blockchain!
