Incoming transactions show up in your account right away (typically within a minute) but will be tagged as 'Pending' until there has been at least one network confirmation. The time it takes a transaction to be confirmed depends on the fee used by the sender and the overall network traffic.
Once a transaction is verified, the pending tag will be removed. This lets you know the transaction cannot be reversed and the funds can be sent.
This verification process is similar to the 2 - 3 day hold traditional banks put on check deposits waiting for funds to clear. Digital asset networks have a similar system except this time spent waiting is reduced to hours (and sometimes even minutes with faster networks like Ethereum) instead of days.
|Asset||Typical Pending Time|
|Bitcoin||60 minutes or less|
|Dash||15 minutes or less|
|Dogecoin||15 minutes or less|
|Ethereum||5 minutes or less|
|Golem||5 minutes or less|
|Augur||5 minutes or less|
|Litecoin||15 minutes or less|
Occasionally, transactions are not accepted by the network and remain marked as 'PENDING' for 2-3 days. Typically these transactions will never confirm. These problem transactions are typically caused by three main reasons:
If you have a transaction in your account that has remained pending for more than 3 days you can manually remove this transaction by refreshing your account. Transactions that don't confirm are returned back to the sender.
