Thank you for the list.

New websites found recently:

• https://www.viabtc.com/tools/broadcast
• https://pushtx.btc.com/
• https://cryptocurrency360.com/bitcoin-accelerator/

Some require the TX (acceleration services) whilst others require the RAW transaction.

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.

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"


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.

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/

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.

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...

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.

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.

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 have just moved blockexplorer.com from the BTC to BCC/BCH due to the following message on their website:

If I see any I'll post them.

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

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

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.
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.

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?

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!
