Thanks, but you don't have to.

I already have something working (I'll create a thread if I make something more fancy).

https://fees.ninjastic.space/registerWebHook?url=DISCORD-HOOK-URL&coin=BTC&targetFee=10

To alter/update the targetFee, just use the exact same URL but changing its value.
To stop/remove it altogether, also use the exact same URL but with the parameter &stop=1.

The bot will check the mempool.space fees every 30 seconds and post a message on your channel if the halfHourFee value is less than or equal to your targetFee. If the message is triggered, it won't do it again until after 30 minutes (even if the targetFee is still met).

I'll work on a Telegram and ETH version later.

If somones makes a json scraper/webhook for this and ports it to TG & DC announcement channel so when fee is low it notifies when mempool is cheap and etherscan gas prices are low id gladly tip them

Let's see if @TryNinja is up for this

WIP.

You will be able to register your webhook url, target fee and coin (BTC or ETH) and the bot will send a POST request with the details whenever the target fee is met, which sould work with Discord and maybe Telegram. What do you think, @WhyFhy?

I've been wondering why people are tagging , Its just dawned on me you've made a replacement for piggy!
I'm currently building on YAGPDB but relatively new to the discord scene as far as administration goes, can I ask about how long it would take? I'd like to tip correctly ! I wont be capitalizing on it therefor I don't wanna put a lot into it, I'm investing/deploying in a 3 coin pool currently. But it's community based luck pools.

@mocacinno did a quick-and-dirty 10 minute sollution https://github.com/mocacinno/autofeechecker thanks to him.
I think that's enough for now. If there is someone who loves development, the door is open.

If you want to pay 10 sat/vbyte you should just pay that amount and wait for the transaction to confirm. You won’t get any benefit from waiting for many transactions confirming that pay this rate.

Many services require a transaction to be confirmed within a certain amount of time. This doesn't matter for an online casino, but for an instant exchange or virtually any site that uses a payment processor your unconfirmed deposit shouldn't take weeks.

You are describing situations in which people are effectively selling their coin in fairly small amounts. I don't think tx fees would be a high priority for people in these situations. I think people would care more about the need to buy x, or the rate they are getting.

Also, in my experience, it is more common for sites to require that a tx is 'seen' within a certain amount of time, not confirmed. If you send a tx right after three blocks are found in a short period, and it takes the next two blocks 90 minutes each to be found, paying tx fees consistent with 2-3 block confirmation time will probably still take several hours to confirm.

Have you ever used a service that doesn't allow for you to adjust your fee? Like Nicehash for example? I see where your coming from though.

(would API's work?)

Yep , I imagine it works the same way the sneaker/gpu bots work , a little py/macros beanloop json scraping magic.
I dabble enough to know its possible but don't know enough to execute. Not in a timely fashion for a webhook ill never make anything off of.

Not withstanding the above, are there any sites that have corresponding Twitter feeds? If you had an alert for whenever a tweet has corresponding information, that might be a work around to being unable to get the information directly off of websites.

I have my reasons. Usually when fees are high I return to it later.
Anywho offer still stands if anyone else is interested. PM me.

Is there any site that tracks Bitcoin transaction fees (real-time and not estimated values) giving me notice when fees are low or at least when mempool is empty?
I need a site work as https://coinb.in/#fees I set the input/output address type and it gives me noification when fees goes down or XX Sat/Byte.

This is a fantastic idea.

The only fear that I have with push notifications is that I would miss it as it is temporary. If I happen to be on another device at the time of the fee drop, then I might miss it altogether.

But I agree, this would still be better than collecting emails and having a mailing list from a privacy perspective.

Also, I feel like if this initiative was to become widely adopted, then it could actually aid the fee hikes big time - people are able to consolidate their inputs during relatively calm periods, pushing fees up during these times, whilst also reducing the amount of transactions and coin inputs when the network is busy, which obviously helps keep fees down. Would be interested to see this become more than just a community experiment.

I just want to think what is the best way to alert the user: email, desktop notification...

I will be follow-up if you want any lack, I am ready, I do not have technical experience< I will try to devote an hour or two hours a day to trying to create this thing.
It won't be complicated, just notifications on desktop or color {red and green} and number of sat/byte Extension/add-on on chrome and Firefox.
email notification will be annoying.

this will be good https://www.eyeswift.com/wp-content/uploads/2016/08/pushondesk.png

This is still work in progress done in free time, so any feedback, testing and donations are appreciated.
Check out some screenshots:

This would be great, if add-on is open source and does not contain a lot of codes which is easy to verify. there is no objection to installing and supporting it.

i will try it on Firefox.

And I said accelerators since if it would be only ViaBTC then this would not be a problem (do you expect ViaBTC mine multiple blocks in a row?)

Too damn early to even try and think of the possibilities and no amount of coffee will make this possible at the moment, I know I've seen VIAbtc mining two in a row , at 7%(?) that chance would be indeed pretty slim but there are some more like it, plus there are CPFP transactions, too me sincerely it looks like a bit too much trouble to start from the last block info.
Of course, you could do a median, you could exclude x amount from the bottom, but the laziness in me has the upper hand right now, just thinking that you would also have to add the possibility of an empty block getting mined and in that case, more and work, no Cheesy

It would be advantageous to monitor ~~the~~ your node's mempool for outstanding transactions as of when blocks are found. If there are zero or close to zero transactions paying above a certain fee rate, you should be able to reasonably conclude that paying that feerate should get your transaction included in the next block if it were broadcast in the next second.

You should not wait until the mempool is empty/less full to broadcast a low-fee transaction. There will be times in which many blocks are found in short periods of time, and the last block found in that sequence will confirm transactions with low fee-rates while the next block might require a fee rate much higher than the previous block.

If you want to get a transaction confirmed with low transaction fees, you should broadcast the transaction, and wait for it to be confirmed. You are already waiting, so you might as well have your transaction outstanding in the mempool.

I'm glad that a reputed member does this instead of seeing the feature on a website nobody knows about and may only collect e-mails for further spam.

Thanks.

I don't want to collect e-mails, create a mailing list, etc... I don't like this ancient internet practice of collecting email from users.

I will try to make Push Notifications, which I believe is a more modern and less invasive practice on user privacy in my opinion. I am busy recently, but I will make it soon.

something like this:

I wanted to have something similar so I found a developer who made something like this for my personal use.
We have an idea to add this notification feature in our open source BTC Mempool Fees Extension/add-on for Firefox/Chrome browser but it will not be ready any time soon.
For now you can monitor mempool fees 24/7 in your browser ticker with our extension, using mainly mempool.space website or two other alternatives, so you will see very easy when fees go down and mempool clears up.

This is still work in progress done in free time, so any feedback, testing and donations are appreciated.

With APIs you can always have multiple sources to get data from, quite improbable they could go all offline.

APIs are usually not too happy to get accessed (too much) for free.
I had my own share of experience with API cutting me off for no particular reason, and I've accessed it under 1000 times spread over 3-4 months.
Multiple APIs may fix this. But I've learned to use my resources when that's possible.

But I am confident that a good analysis can be done with the mempool at hand (ignore the smallest 150-300 tx fees from a block?), without calling a 3rd party API.

Why not? You would need to run our service 24/7 and for it to be completely reliable which is not something a home run node can excel at, same for taking care of your own server, the fewer things are needed the less might go wrong.
