Hello,

Without working with a third tier service that could take fees or limit my account, I would like to create wallets, check transactions and send btc with PHP.

Each user would have a unique public key to make donations. All I want is to be able to generate a unique one for each user, and to check for transactions regularly, in order to transfer its balance to a main wallet.

So what I need is:

• Create wallets (Public & Private key)
• Create transactions
• Check for transactions and balances

I want to be as dependent as possible, so without API keys or something like this.

How can I perform this?

Thank you by advance

The donating of gas fee won't be that sustainable long term especially if the token is having lots of transactions. Some could even abuse it by deliberately/unintentionally draining the reserve with unnecessary transactions except ofcourse the token devs or site owner make it one or few transactions per unique address or something.
It's good you considered doing something about it. You still could try other interesting ways people/things that can't afford it can send token without bothering about gas fees

Hello I'm new here
I have a few questions regarding a project idea that I have, I understand nothing about development neither coding

I would like to create a website with football stats, more specifically The corners Stats (For example team A on the last 10 games have a media of 5 corners per game)
All the information would come from this website https://www.flashscore.com/ ( Flashscore.com)

So my questions are
How should I try to find someone that can do it? How can I explain it to him ? Since I don't know what type of code language
And since I'm completely new to this type of service, how much could it cost?

Would really appreciate some feedback and answers
Ps: I'm new here so I think I put this on the right furom (if not, I'm sorry)

If you're planning to have more than a handfull of active users, i'd defenately start by running your own bitcoind instead of using blockcypher's api.

When configuring the bitcoin daemon, use notifyers as a hook to your update script, that way your database will stay up-to-date.

I'd probably use a combination of -walletnotify and -blocknotify, and maybe poll the mempool from within the user's account overview page for incoming, unconfirmed transactions.
Make sure you either have a watch-only wallet, or make sure your hotwallet is properly locked.

Yes! It is one of the major issues. Due to the high competition in the e-com market, all stores are forced to keep their profit margin lower. So it is very difficult to sustain a business with such a small profit market and huge price volatility. 


No! We have big players available in the logistics industry to help new businesses. They are even ready to provide discounted rate if you are just starting out. So logistics is not an issue whatsoever.


Somewhat true! However, we have services like Bitpay, Polispay to overcome such issues. Even LN has already started functioning. So speed issues can be taken care. There is another one issue you have missed out - Crypto regulations. If we leave some countries like Japan or Germany or even US, majority of the countries don't have any regulations around crypto currencies. For majority of the countries, crypto is not even a legal form of money. That's what needs to be sorted out first if we really want to see a big marketplace in crypto market.

This post shouldn't be in this subforum because you are asking about Ethereum-based tokens. You should probably move it to Altcoin discussions.

To answer your question. MyEtherWallet has an Android app. Have you tried that? it supports all ERC-20 tokens. You can add the ones that are missing using the contract info.

I am not sure if this is an official MEW app or not so use it at your own risk! Maybe wait for some other members to chip in with their comments.

MetaMask is also available on Android and iOS.

I don't think there's too much of an issue, I think it's just that sites want to be abl eto trust their payment source and cryptocurrency is pretty new - they like what ha salways worked for them...

I've bought things with bitcoin from places like scan.co.uk and they've been pretty good with everything. There's the additional problem with bitcoin in that returns aren't as easy to handle (imo) and transaction fees might have to be returned too a sther'es no RTS (return to sender) script in eveyr transaction that can be signed and returned to the previous owner for free too...

As i know there were special addon for amazon to pay there with LN. Any you can find guys who are selling gift cards for crypto

Thanks to @NAVI12 for donating this signature design to us. It's a pleasure working with him.

I don't think that it would be possible in future, even though cryptocurrency has been used by so many people around the world, even though it is really helpful for everyone who is using it, it cannot still be a standard currency in the future because as what we all know it is decentralized, which means it cannot be handled by the government and its volatility makes it not suitable to be used for daily lives.

I think cryptocurrency is only good as an alternative currency for fiat currency, it is meant to be converted to fiat currency whenever we want to.
