Bitcoin transaction stuck or unconfirmed? Confirm it faster.
A low fee rate leaves your Bitcoin transaction waiting in the mempool, and the coins it spends stay locked until it confirms. FixStuckTX checks your transaction on the live mempool and raises its effective fee rate — via RBF or CPFP — so miners include it in the next block, usually within 10–30 minutes.
Paste the receiving or sending address. We read it straight from the Bitcoin mempool (mempool.space) — we never store it.
How it works
We read the mempool
We look up your address and transaction on the live Bitcoin mempool and measure its fee rate in sats per byte against the current threshold.
We raise the fee rate
If the original used RBF, we broadcast a higher-fee replacement. Otherwise we use a CPFP child transaction so miners confirm both together.
It confirms in 10–30 min
Once the effective fee rate clears the mempool threshold, miners include your transaction in the next block or two and it reaches its first confirmation.
Why Bitcoin transactions get stuck
Fee rate too low. Miners fill each block with the highest-paying transactions first. If your fee rate (sats per byte) is below the mempool's current threshold, your transaction waits — sometimes for days.
Coins stay locked. While a transaction is unconfirmed, the coins it spends cannot be spent again. So a stuck transaction also freezes the funds it touches.
No nonce queue, but a fee queue. Unlike Ethereum, Bitcoin has no per-address nonce ordering — but it has a strict fee-rate queue. A low-fee transaction sits at the back until the fee becomes competitive.
The fix: raise the effective fee rate — replace by fee (RBF) if available, or pay for the parent from a child transaction (CPFP).
Frequently asked questions
How long does it take to confirm a stuck Bitcoin transaction?
Once the effective fee rate is at or above the current fast threshold, confirmation usually lands in the next one or two blocks — roughly 10 to 30 minutes.
Is it safe to enter my recovery phrase here?
The phrase is used only to build and sign the replacement transaction in your browser tab. We recommend doing this on a device you trust. For extra caution, move only the funds you need first.
What is RBF and do I need it?
RBF (Replace-By-Fee) lets you replace your own unconfirmed transaction with one that pays a higher fee. It must have been enabled when the original was sent. If it was not, a CPFP child transaction is the alternative.
Are my coins lost while the transaction is unconfirmed?
No. They are reserved by the unconfirmed transaction. They become spendable again once the transaction confirms, or are redirected by a successful replacement.
What is sats per byte (vB)?
It is the fee rate: total fee divided by the transaction size in virtual bytes. Miners rank transactions by this number, so a higher sats/vB confirms faster.
Can I send another transaction while one is stuck?
You can send a transaction that does not spend the stuck transaction's outputs. You cannot double-spend the same coins until the stuck transaction confirms or is replaced.
