Bitcoin Forum

After seeing people charging and deceiving people into paying for a service that is free, I have decided to make a list of the free Bitcoin Transaction Accelerators that I know of. I will try to keep it up to date. Please feel free to add any others you have found, and I will update the list in the OP.

To get your raw transaction details from blockchain.info, you need to do this:

Take this transaction for example: https://blockchain.info/tx/09ecd47c084613bb992e4ad50e4639008f61f2295dc1dbd5ce14d46975ee1f38

In the URL section, you need to add "?format=hex" behind the end of the transaction, like this: https://blockchain.info/tx/09ecd47c084613bb992e4ad50e4639008f61f2295dc1dbd5ce14d46975ee1f38?format=hex

You will then be given the raw transaction details in your browser.

Another method is to use the smartbit API.

https://www.smartbit.com.au/

Enter your transaction reference in the box provided, hit enter, and on the right hand side click the 3 dots, and click "Transaction HEX". Bingo. Use that in the services below.

Did you add antpool's one? https://www.antpool.com/user/prioritiseTransaction.htm?m=savePrioritiseTx

Great to see an alternative to the typical "please send me tip and will make ur transaction go zoom zoom"

Good work Z!

Nice list! Will keep following this.

Concider adding http://confirmtx.com (http://confirmtx.com) to the list, which is free for transactions up to 400 bytes.

And someday someone was begging for an acceleration . Here comes another moron .

And someday someone was begging for an tip. Here comes another moron .

Copycats . Go get a life !

They are not the accelerator or they are? We can only broadcast our tx with them.
Still good to see you come up with this idea, it will help members to know about popular free accelerator services.

Thanks for the additional link aTriz!

Not often I have to use a tx accelerator, so don't know all of them. Will keep adding them as people post :)


Excellent. Thanks for your contribution :)

Added to OP.


Stop deceiving people into paying for a service that isn't yours.


You make a fair point. Those initial links are just to rebroadcast a tx using other nodes, which I have found does sometimes speed up your transaction.

Nonetheless this thread will serve its purpose if others' add actual accelerators.

Thanks for your post.

I never deceived people . I do this for free . You are another moron . You never told how to broadcast a transaction .

Thank you for providing us the list of free bitcoin accelerator services, let me subscribe here cause I know this would help us a lot in terms of receiving and sending bitcoin transactions that sometimes stuck up or has delay confirmations.
No need to pay those users who are claiming as their own but tip or donation is okay for me.

Thanks for the heads up. I will add that to the OP.

:P

add this one https://pool.viabtc.com/tools/txaccelerator/ , it still working even if they doesnt accept transaction that have fee under 10 sat/b and just accept 100 transaction/hour

Yeah, thanks, that's very handy!

excellent, nice work zepher  8) thanks for letting the community know about these free services.

Thank you for this Sir Zepher!

Can someonw help me i tried everything

This is not a service where I try get your transaction confirmed for you; this is a "Do it yourself" thing.

Your raw tx is:


Your fee on this transaction is just 5 sat/byte, I think you might be waiting a while for this to confirm (if ever).

Paste the above code into the links in the OP. Hopefully it confirms, but I wouldn't get your hopes up.

Yes i already did it, really sad.

what hapenn guys ?
i think is good ...? what the risk?

Stop spamming nonsense.

If you don't understand what is being said, don't bother replying.

90% of the items in list are not txn accelerator.
Huge difference between broadcasting and accelerating.

Only the last 3 (or technically 2, because ConfirmTX is very very likely to be just resubmitting into AntPool's accelerator) actually accelerate your transaction by getting a mining pool to confirm it. The others will help broadcast the transaction if there is bad propagation, but almost all of the time it is not the case and the reason for the transaction being unconfirmed is a low fee. Rebroadcasting won't help a low fee transaction, and it could make it worse if you want to double spend with a higher fee.

Yup fair enough and I realised this soon afterwards. I'm just trying to stop people charging for something they don't actually own. Hopefully people keep adding links to actual accelerators so this thread achieves its purpose. If you know of any, please link them.

Thanks for the comment!

https://webbtc.com/relay_tx is bugged. Says "Error: getaddrinfo: Name or service not known" when all the rest up to that point had returned a valid TXID.

Then https://live.blockcypher.com/btc/pushtx/ threw "Error sending transaction: insufficient priority and fee for relay." so it should probably be deprecated if they won't disclaim up front what would be sufficient.

https://www.antpool.com/user/prioritiseTransaction.htm?m=savePrioritiseTx which redirects to https://passport.bitmain.com/login?service=https%3A%2F%2Fwww.antpool.com%2Fuser%2FprioritiseTransaction.htm%3Fm%3DsavePrioritiseTx is registration walled.

https://pool.viabtc.com/tools/txaccelerator/ should probably have a disclaimer next to it (at least until they change their policy on the site) that the minimum is 10 sat/byte aka 0.0001 BTC/kb.

Great Post !!!

Thank for sharing this information.  :)

Bumping this thread so that people can know how to accelerate their own transaction and not seek people's so called "services" and provide a 'tip' for that. A lot of unconfirmed transactions are out there lately..

Hi i am worried about my transaction.
https://www.smartbit.com.au/tx/4a04b28c3401cc458a624968cb22feba8ca820fabe7effca9aeb6c0871566f42

I am waiting from 24h+.Its not showing in blockchain.  I tried to use viabtc accerelator but the transaction have 72sat/b and its not possible to accelerate it. On confirmtx it says transaction does not exit.  Before a few minutes i successfully broadcasted my transaction. I hope to confirm soo because that money are urgent. Alsso what means when the tx is not showing in blockchain but in smartbit its showing.  I will be happy on any help.
thanks in advance

ViaBTC minimum is 10 sat/b. You need to submit TXID at xx:00:00 UTC.

Just want to say, thanks to your thread more, more dickheads are opening their own accelerator service which just uses the free ones listed here. What's worse is that most of them are asking for "tips", as if they did something so hard. 

Maybe, it would be better to tag those people that open this kind of services just to tell everyone that this shit is free and they don't have to pay someone else to do it for them. These people are really taking advantage of those ignorant ones that just want their tx to get accelerated.

If that is free why people don't do on their own and ask for acceleration?

https://bitcointalk.org/index.php?topic=2604643.msg26514864#msg26514864

Check there and answer me if you can.

I would suggest explicitly breaking down this list into two sections - transaction broadcasters, and transaction accelerators.

This would make it more clear what the difference is, especially for newcomers.

Good job Zeph....i have been looking for alternative sites to accelerate my stuck transaction

Thankyou

Hello,

Can you please accelerate this Trx ?

If it got confirmed, I will tip you for sure.
Thanks in advance!

Good idea!

ViaBTC accelerator should be removed. No matter what hour of the day I submit at exactly xx:00:00 UTC, it says:

"Submissions are beyond limit. Please try later."

Yep I get the same message..it used to be a great service..its a shame its not anymore!

I use bitmain's official transaction accelerator since a long time and it works even if your transaction has very low fee.
Bitmain's antpool can broadcast also raw transactions in a short time, i have helped many people getting confirmed their stucked transactions by this accelerator. Don't forget to put this link in your list above, here you can check it  https://www.antpool.com/user/prioritiseTransaction.htm?m=savePrioritiseTx

Hi!
I ve got a stuck transaction for almost 2 days now...
I put a fee of 170sat/B so I don't understand why it is getting so long actually :/
Transaction is 390B
I tried the accelerators but none of them is working: impossible to submit with viabtc even at the hours sharp and I get an error message when using ConfirmTX ("This product has been suspended for breaking our terms of service")
I just tried Antpool but everything is in chinese and I can't translate with chrome somehow...
I get this at the end:
https://img15.hostingpics.net/pics/841700ScreenShot20171221at212541.png (https://www.hostingpics.net/viewer.php?id=841700ScreenShot20171221at212541.png)

Which translate by Acceleration trading ID
Does it mean it is going to work?

If anyone care to help, here is the transaction:

Thank you for your great tutorial. But all the suggested free accelerators don't work anymore.

Enough with the TXIDs. Miners who pay insane fees to themselves to fuck up fee estimators need to be isolated & rot.

I think now its okay and back normal again. Because its easy to submit even im not on time.
