You sent bitcoin, and it is still pending. The fee was too low for a busy mempool, so miners are picking other transactions first. Your coins are safe. The payment is waiting in line.
BlueWallet lets you move it up the line with Replace-By-Fee (RBF). Here is how. If you only want to know what pending means, start with Pending transactions.
1. Check your pending bitcoin transaction
From the home screen, open the wallet you sent from. Tap the transaction in the list.
The blue Pending card means the payment is in the mempool and has no confirmations yet. While BlueWallet shows Analyzing…, it is estimating how long confirmation may take.
2. Tap Speed Up
Tap Speed Up. BlueWallet builds a new version of the same payment with a higher fee and broadcasts it. Miners see the better fee and are more likely to include it in the next blocks.
The recipient and amount stay the same. Only the fee goes up.
3. Or tap Cancel
Changed your mind? Tap Cancel when it is offered. BlueWallet spends the same coins back to your own wallet with a higher fee. Once that version confirms, the original payment is replaced and the funds are yours again.
If Speed Up and Cancel are missing
Both buttons appear only on sends you made from this wallet that support Replace-By-Fee. Received payments show neither, because the sender controls that transaction.
Without the buttons, the payment can still confirm on its own as the mempool clears. During busy periods, that takes patience. You can check its progress with the explorer link and the Network Fee in the Details section.
When pending clears
Once the transaction is in a block, the status card changes. A send turns red and a receive turns green, each with its confirmation count. BlueWallet refreshes this for you. See Transaction status for what each part of the screen means.
Avoid the wait next time
On the send screen, tap the fee estimate and choose a faster rate when the payment is urgent. Sending a bitcoin transaction walks through the whole flow. For full control over which coins pay, use coin control. Built the transaction elsewhere? You can broadcast it from BlueWallet too.
