FREE BTC Tx Accelerators. Stop paying for something that is free!

[pinkman12345]

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.

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?

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

[kkcity]

Hello,

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."

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

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

If anyone care to help, here is the transaction:
d81402c8a26f232075e73cc528e4974cb5cccd7d15d79e40fae9931beccb70c7

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