The Bitcoin toolkit that respects your privacy.
Accelerate or cancel stuck transactions, explore the mempool, estimate fees, and generate vanity addresses — all without an email, password, or KYC.
Free tools, no login
Pick a tool. Use it. Leave. We don't even know you were here.
Stuck in the mempool? Paste your TXID, send 97,316 sats, and we rebroadcast it to 20+ nodes and partner mining pools.
Sent BTC to the wrong address or set a fee that's too low? Pay 317,602 sats and we will broadcast a higher-fee double-spend that invalidates your original transaction — provided it is still unconfirmed in the mempool.
Look up any transaction, address, or block on the Bitcoin mainnet. Powered by mempool.space — proxied through us so your IP never touches the explorer.
Real-time mempool fee estimates. Pick a target confirmation window — we'll tell you the right sat/vB.
Live prices for 50+ fiat currencies. Type any amount — all the others update instantly.
Generate a Bitcoin address starting with letters of your choice. Runs entirely in your browser — your private keys never leave this page.

What people are saying
Real users, real stuck transactions, real fixes. Replace these with verified testimonials from your community.
“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 check this every morning before sending payroll in btc. Cleaner than mempool.space for me, no clutter, just the numbers I need.”
“no signup, no email, no captcha, no bs. paid sats, tx mined, done. how every bitcoin tool should work.”
“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.”
“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.”
“I prefer this over the bigger explorers because it loads in under a second on my mobile data. Shows me exactly what I need, no ads, no popups.”
“Ran 8 worker threads on my m1 max, hit a 6 character prefix in around 11 minutes. Downloaded the JSON, imported in Sparrow, address worked first try.”
“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.”
“Confirmed in block 901512 about 38 minutes after I paid. Tracking page showed me the rebroadcast count rising in real time. Very satisfying actually.”
“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.”
“Was looking for a vanity gen that did not require me to install anything. This one just runs. Found my prefix overnight while I slept. CPU got warm but laptop was fine.”
“Best Bitcoin explorer in Vietnamese I have found. Translation is clear, the interface does not feel like a copy of mempool.space, has its own personality.”
“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
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.
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.
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.
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.
