My tx had been sitting at 1 sat/vB for almost 14 hours. Wallet kept telling me to wait. Paid the fee here, confirmed in the next block. Worth every sat.

Sent BTC with the wrong amount and panicked. Cancel feature actually worked, replacement got mined first. I cannot believe this is free to even try.

Generated a vanity address with my initials in about 3 minutes on my laptop. The fact that it never leaves the browser is what sold me. Open the dev tools, no requests.

I trade between USD, ARS and sats every day. Having one tab that shows all three at once saves me real time. Bookmarked permanently.

Other accelerators wanted 0.5% of my tx amount. That was bigger than the fee I underpaid in the first place. This was flat sats. Mined in 22 minutes.

I use this for verifying customer payments at our coffee shop. Clean ui, loads fast on the iPad, German translation feels native and not robotic. 10 of 10.

Tested this with a low fee tx I sent to myself first. The replacement broadcast worked, got picked up by F2Pool. Now I trust it for the real ones.

Was honestly skeptical about a free tool doing what others charge $30 for. Used it twice now. Both confirmed under an hour. Telling everyone in my Telegram group.

Made an address starting with my dog's name for a present wallet. The page told me how long it would take before I started, which I appreciated.

Honest, accurate sat/vB readings. I cross checked against my own node and the numbers match. That is rarer than it should be.

Switched currency to JPY, typed sats, got yen instantly. The whole interface respects my time. Japanese translation is also natural, not auto translated feeling.

I had a CPFP child stuck behind the parent. Paid the accelerator fee on the parent and both confirmed in block 901248. Saved me writing a python script at midnight.

Cancel TX

Sent to wrong address by mistake (paste error). The cancel page was very clear that it might not work, and explained why. The replacement won the race. Refund situation avoided.

Useful when I send remittance to family. I check ZAR to sats here, then send. The rate matches what I see on Kraken within 0.1 percent. Good enough for me.

OKX wallet sent my tx with way too low fee. Was panicking. This site fixed it for ~$30 USD worth of sats. Other sites quoted me $200+ for the same thing.

Probably the cleanest fee estimator I have used. The cost calculator at the bottom is a nice touch, helps me explain to customers why their withdrawal will cost what it costs.

I use this as a calculator at work because the design is just better. Korean translation reads like a real person wrote it. Bug me when I find something to fix and I will report it.

Finally a service that does not ask for my email to use a tool I am paying sats for. The privacy claims actually match what the network requests show.

My exchange withdrawal got stuck after they raised fees mid send. Tried cancel, it succeeded because the original was RBF signaled. Got my coins back to a different address.

Loaded the page on a slow 3G connection and it still worked. That tells me the team actually cares about people who are not in San Francisco.

Mi piace molto. Italian translation is excellent, and the swap button between BTC and sats is in the perfect spot for thumb use. Small detail, big difference.

I refresh this page every couple hours. Fees graph would be a nice add but honestly the current numbers are enough for what I do. Solid work.

Sent a tx without RBF and it sat for 6 hours. The honest disclaimer about lower success rate was appreciated. It actually worked anyway, so bonus points.

Frequently asked questions

Is the accelerator really free?

Yes. We charge a single flat fee in sats (97,316 sats per transaction) that covers our priority node fan-out and direct mining pool relay. There is no "premium tier" — what competitors gate behind $20+ paywalls is included.

Do you log my transactions or IP?

No. We don't store TXIDs, addresses, payment metadata, or any IP information. The accelerator is stateless: once your TX confirms or 24h pass, all in-memory state is gone.

Why isn't my transaction confirming even after acceleration?

Acceleration increases the probability of inclusion in the next ~6 blocks but doesn't guarantee it. If after 24h the TX is still unconfirmed, we automatically retry the rebroadcast. You don't pay extra.

Do I need to sign anything or connect a wallet?

Never. Paste your TXID, send the sats from any wallet, click verify. We never ask for private keys, seed phrases, signatures, or wallet connections. If a service does — leave.
