The wiki (https://en.bitcoin.it/wiki/Transaction_broadcasting) has a couple more

• https://blockchain.info/pushtx
• https://insight.bitpay.com/tx/send
• https://www.smartbit.com.au/txs/pushtx
• https://coinb.in/#broadcast They can broadcast through different services https://coinb.in/#settings

And of course my favorite method ... drum roll ... Push directly to the network by contacting nodes via a simple code. Basically the "Sending a transaction: tx" part of bitcoins hard way article (http://www.righto.com/2014/02/bitcoins-hard-way-using-raw-bitcoin.html).

Thanks for the information, I've updated the OP and I'm just combing the Wiki for additional URL's.

(Have also added Moloch's Bitcoin Transaction Broadcaster http://services.moloch.net/broadcast but am getting Failed To Connect: Connection Refused error message.

Yeah, that's why I didn't post it. I could never push anything with Moloch's tool!
The same with webbtc, it was working for some time but I guess their node is no longer updating. It is stuck on block 443888.

Some shameless promotion, but my website also allows you to push raw transactions to my own node:
http://www.mocacinno.com/page/txpusher

BTW: if you want to keep your thread clean, PM me if you want me to remove this message after you've read it :)

Thanks for the heads up, I've added your URL to the list (am going to add to the bottom for now and maybe later will alphabetise the list).

No need to delete your post, it might encourage others to post their links too.

I don't think you should have the Transaction Fee Booster listed here. It's currently unmaintained, has some weird bugs, and can be a bit difficult to use.

---

People who run Bitcoin Core nodes can also use the sendrawtransaction rpc command to broadcast any transaction which they have the hex for.

Good list and good guide.
Probably for more advanced users, not too much people need to send raws.
Anyway, any guide which can help some bitcoiner is good thing for bitcoin, kudos to you!

I've amended the listing to show that it isn't working.


Thanks for the kudos, any guides are good guides. :)

Suggestions and more details always appreciated.

Have added four more from the Wiki Page that are working:

• Broadcast Raw Transaction   https://www.localbitcoinschain.com/tx/send -
• Bitcoin Relay Transaction   https://webbtc.com/relay_tx -
• Push TX (f2Pool)      https://www.f2pool.com/pushtx -
• Push         http://eligius.st/~wizkid057/newstats/pushtxn.php -

I've also used random.org 's randomiser to resort the list of sites so as not to show favoritism to any one site (and I'll probably re-shuffle the list periodically so the ones at the top of the list don't get all the traffic)

Just a little project:
SharpPusher, broadcast bitcoin transactions to the network (https://bitcointalk.org/index.php?topic=1944501.0)

https://i.imgur.com/8LCL1gZ.jpg

Just some points:
The blockchain.info API has proven to be a bit tricky! So please let me know if you encountered any weird responses.
This is for Windows only (sorry!). But I have .Net core in my learning backlog and will make it multiplatform in the future, hopefully.  ;D

Can this be ported for use with PortableApps.com?

I am not familiar with that APP but took a quick look at their about page it seems like it will work.
My code doesn't need installing, you just have to compile it and you can just simply transfer the bin folder to any other computer running on windows (since it needs .Net framework) and double click and run it.

Technically the whole bin folder is not even required. It will need only these 3 files:

Hello, thanks for letting me know this thread, I'm also having a TX accelerating service thread at,
https://bitcointalk.org/index.php?topic=1934749

I'd like to add something since this is for beginners, there's a big difference between broadcasting transaction and accelerating transaction.
The former one doesn't "confirmed" your transaction, but just broadcast it to the network,
the latter one is usually a paid services where we subsidize the miners from mining pool to prioritize on including your TX to next block regardless of your fees.

I'll add you listing under There are also two services that will process your TX transaction:

Perhaps I should add "For a fee"?

This is a nice list.

Here's one to consider adding under Predicting Bitcoin Fees:

https://jochen-hoenicke.de/queue/#2w

It's better for seeing trending direction of the mempool.

Have added cyyap95's TX accelerating service thread and the vh suggested Predicting Bitcoin Fees: https://jochen-hoenicke.de/queue/#2w

Am just trying to get some formatting sorted.

Have added https://bitcoinfees.github.io/

Many thanks.

Another one, with fees estimation which I like it firstly for its simplicity and secondly because plots the distribution of fees in unconfirmed transactions here (http://bitcoinexchangerate.org/fees)

Have added http://bitcoinexchangerate.org/fees to the list of other related services - not sure why it thinks a lower fee will get a transaction into the next block while a higher fee will get into a block in an hour to twenty-four hours, but it gives some interesting data.

What about pushing BitcoinCash transaction?

Thank you

I'll keep an eye out for any such beasties...  
Given that BitCoin XT is a direct clone of the Core wallet you can push a transaction yourself.  (See my first post)

OTOH, BitCoinCash is a scale-able block concept, I'm guessing most punters will dial their "Pay only the minimum transaction fee" down to the bare minimum of 0.00001000 BCC/BCH per Kbyte as that BitCoin clone will probably sweep up all transactions and just grow the block size, so there won't be any real need to pay a little bit extra to get into the next block as the block will just keep growing to accommodate all transactions...  QED.

Unless I'm mistaken?

C.E. to da rescue:
http://blockdozer.com/insight/tx/send

This doesn't have an API otherwise I would have added it to SharpPusher™ already...

My code about the part "pushing the tx directly to the network" is nearly ready. I have not got the time to test it with real transaction yet. I can practically make a node with minimal functionality to just broadcast, I just have to make the code pretty and remove the bugs (DAMN BUSY LIFE).
Also I have no idea how to differentiate between nodes on different network. if you know how point me in the right direction and save me a google search ;)

According to https://blockchair.com/bitcoin-cash/blocks the fee/kB (I don't know about the accuracy of it) is about 0.0009-0.0011 BCC/kB

Thank you very much!
I have created, signed the raw transaction BCC using https://coinb.in/

and then tried to broadcast using blockdozer
An error occured: Missing inputs

Ok, I'm still experimenting

Added support for BCC to SharpPusher™. Only has 1 API though.
https://i.imgur.com/WgTTgwN.jpg

Am pretty sure I've caught up on all the links, if anyone has been left out, drop me a note.

I don't think you can sign raw tx BCC with coinb.in
isn't coinb.in on bitcoin chain... and bcc has two-way replay protection?

please update with BCC compatible tx pusher & perhaps tx tool if any available soon
I'm pretty sure many of us waiting and appreciate for the BCC part...  ;D
and I think you should move blockdozer from bitcoin to bitcoin cash section
I looked at the blockdozer page... it mentions BCC

Found another for BTC, BCC, LTC. Here is the link for BCC:
https://pool.viabtc.com/tools/BCC/broadcast/

This does not belong here because it doesn't accept "bitcoin" transactions.
Also as an update, blockdozer does in fact have an API. It is the same as most insight APIs (it is just hidden).
You post the raw transaction with they key rawtx to this address: http://blockdozer.com/insight-api/tx/send
Here is how I do it in SharpPusher (https://github.com/Coding-Enthusiast/SharpPusher/blob/master/SharpPusher/Services/PushServices/BlockDozer.cs)[/list]

One of the many problems with keeping a list is the occasional cut and paste going into the wrong section.   :o  Have moved the blockdozer entry to the BCC/BCH section.   8)

Am just looking through the last part of your post to ensure I get the posting of that information in the correct section and transcribed correctly.    ;D

I've had to remove the following as they no longer work.

• Raw transaction push   http:// btc.blockr.io/tx/push (BCT ANN ?? please)

URL redirects to coinbase.

• Transaction Accelerator   https:// www .viabtc .com/tools/txaccelerator/ - Quickseller (BCT ANN ?? please)

And their website says:


(Oddly enough https:// pool.viabtc.com/tools/BTC/broadcast/ still works)  ::)

Fixed URL for http://bitcoinexchangerate.org/fees (http://bitcoinexchangerate.org/fees) (didn't have URL BBCCODE , so added that to make link click-able)

• https:// chain.so/btc

Server not found...  ::)

All the BitCoinCash links are still active (including the https:// pool.viabtc.com/tools/BCC/broadcast/ link ::) )

---

All the LiteCoinCash links are still active (including the https:// pool.viabtc.com/tools/LTC/broadcast/ link ::) )

Is there a service that exposes a public API that lets you do this? Similar to how Infura or MyEtherWallet does for Ethereum...

I've looked at all of the above links and they look like they just provide a landing page where you can manually submit a signed hash but there's no way to automate this.

Look closely, usually at the bottom of the page. You can always use your browser search function (Ctrl+F) to search for the word "API", you will find the link. Most of the block explorers do have an API.

If you still couldn't find it, say for what coin and which block explorer so I can post the direct link here for you!

Thanks, I am aware that you can inspect the network request and use that URL to make a form submit request, like you did in one of the posts above https://github.com/Coding-Enthusiast/SharpPusher/blob/master/SharpPusher/Services/PushServices/BlockDozer.cs

But I think calling that an API is same as calling all HTML forms on the web an "API". You can theoretically take any form on the web, take their URLs and emulate submit, and call that an API. But you wouldn't be able to rely on it since they can always block you from using that approach.

None of the sites mentioned on this thread as far as I have looked into has an actual public API endpoint, which was what I was asking for. Services like Infura or MyEtherWallet have an official "API" page that makes it public that they want people to use their node as a broadcast service.

The problem with emulating form submits from the sites mentioned on this thread is you can't really rely on them because they never said it's OK to use their form as your API. If you rely on them to build something, you can never be sure that one of them will just block you one day.

I was looking for a service that explicitly provides a public API for bitcoin transaction broadcast, and it would be interesting if there isn't one. (My followup question would be, why doesn't it exist, unlike Ethereum?) Or maybe I'm misinterpreting this and actually all of those sites--which seem to be powered by the same open source project--DO provide the API implicitly by default?

I'm not sure how these Ethereum APIs work and how they are different, but these block explorers usually have an actual API service that you can use. Blockdozer for example is based on Insight API, which as you guessed is powered by the same open source project. They just didn't make a documentation page (http://blockdozer.com/insight-api/).
Blocktrail: https://www.blocktrail.com/api/docs has both BTC and BCH

And you will have a better luck finding them for bitcoin:
Blockchain.info: https://blockchain.info/api
BlockCypher: https://www.blockcypher.com/dev/bitcoin/
smartbit: https://www.smartbit.com.au/api
and lots more.

I've just come across this post, has anyone used this service?  Should I post it here?

Do you have any suggestions for broadcasting raw transactions for recent bitcoin forks?
United Bitcoin
Bitcoin Diaomond
Bitcoin File
Super Bitcoin etc...

If I see any I'll post them.

I have just moved blockexplorer.com (https://blockexplorer.com/tx/send) from the BTC to BCC/BCH due to the following message on their website:

As the thread title allows to ask about alt-coins too, my question: is there a broadcast tx service for Bitcoin Diamond?

I couldn't find any, although I've found one for almost any other conceivable hard fork (clams included). Thanks. Any help appreciated.

I haven't heard of any as yet, but am happy to add to the list if you find one.  The principals should be the same across almost all flavours if you use the console commands.

I have not found one, unfortunately.

But such services exist for
BitcoinX (tested, it worked): https://bcx.info/tx/send
Clams:  https://just-dice.com/pushtx

Actually I think each and every coin (but Bitcoin Diamond) has such a service.

Thanks for the info, I'll add the info to the OP in the next day or so.

*edit*

I'll tidy up the formatting in the next couple of days...

One more service: Bitcoin Gold https://btgexplorer.com/tx/send

Maybe it is worth to explain why I think that such services are very usefull for minor bitcoin hard-forks. It is because you don't need to wait for your core node to fully synchronize when claiming those coins: the moment you can see your founds (say, from 2015) you make a transaction. Of course, it is not broadcasted because your node is not fully synchronized, but you can copy the tx and paste it into the broadcaster and broadcast it via the external service. It may save weeks of waiting for the full sync.

With the price of Bitcoins on the rise, it's timely to remind people that they can view the current trend of prices to confirm transactions here: https://bitcoinfees.earn.com/

please stop recommending this website, the suggestions have always been terrible because they inflate the fees for some reason and currently the suggested fee is pure bullshit.
https://bitcoinfees.earn.com/ is currently suggesting 160 satoshis/byte for "fastest and cheapest transaction fee"
https://i.imgur.com/YKkU91R.jpg

but analyzing the mempool (which is what i recommend) suggests that paying 20 satoshi/byte will give you the "fastest and cheapest transaction fee" and if you wanted a better guarantee you can pay 30 which is A LOT smaller than the fee suggested by bitcoinfees.earn.com website.
this is the best website you can use:
https://jochen-hoenicke.de/queue/#0,24h
and here is how it works. you look at the chart called Mempool size in MB because the size matters not the count. then move your mouse over the last part on the right which is the current state and look at the numbers. bitcoin block size these days are around 1.2 MB so you want to pay a fee around that size, basically anything above 1 MB. currently it shows that about 1.043 MB transactions are paying fees equal to and bigger than 30 so paying anything above 30 is an overkill.

Hi and thanks for passing on the information; just a couple of points: it's not "my" site.  I was only using it as an example of how many transactions are currently sitting in mem-pools around the world and what the current trends are.  The point of the thread is to minimise TX fees as well as to get those TX's moving.

Kudos for your link.

New websites found recently:

• https://www.viabtc.com/tools/broadcast
