Setting Up a Bitcoin Wallet System for My Website

Hey everyone. I’m working on a website for a game where players can use Bitcoin to compete against each other. Problem is, I have zero clue how to set up a wallet system for users. I know many sites generate unique Bitcoin addresses for each user, but how do I connect it all to my site?

You should definitely look into Bitcoin Core, like the bitcoind version, not the GUI one. It's more reliable for what you need.

Exactly, you’d be using a custodial wallet, which means you control the private keys, not your users. Just a heads up: using web wallets can be risky. Remember, not your keys, not your coins.

I couldn’t find anything on "bitcoind". Only saw Bitcoin Core on bitcoin.org. Is that what I should download for JavaScript?

So, bitcoind is basically a daemon that syncs the blockchain and verifies transactions. You can interact with it using bitcoin-cli. The graphical version is easier if you don’t want to mess with command lines.

Any block explorer can show transaction amounts, no need for walletexplorer.com. And yeah, most casinos use deterministic wallets where each user gets addresses derived from a single seed.

The OP wants to tie his addresses to game users. That’s not really what WalletExplorer is for. It’s more of a chain analysis tool than a wallet.

I went to download and ended up on bitcoin.org. Tried linking it to my JavaScript but ended up needing a node. I must've messed something up.

Post is right. Plenty of platforms run deterministic wallets for users. You can't just say "same wallet" better to think of it as using the same seed for multiple addresses.

Not sure if there’s any software that fits perfectly for what you’re asking. Have you looked into BTCPay Server? It might be what you’re looking for.

Yeah, BTCPay Server has an API for custom integrations, but not sure how well it would work for a casino. Maybe try contacting other casinos for advice?

Thanks for the tip! BTCPay could be useful since other services have so many KYC requirements. The downside is it doesn’t easily connect to databases.

You want your custom payment system, so you’ll need to build your interface. Can’t blame Bitcoin for that.

Mostly true. Companies tend to develop their own software or use third-party solutions. bcoin is pretty solid, but development is slow at the moment.

True, whatever option you choose should not run on the same server as your main app. Keep it isolated to avoid security issues.

Surprised nobody mentioned bitcoinjs yet. It’s a key JavaScript library for Bitcoin.

Well, not many of us are programmers here, so I get why it wasn’t mentioned. Bitcoinjs is cool but might lack some wallet features. Also, check out Bitcore; it has some wallet-related functions.

With bitcoinjs, you can generate private keys and wallets. You can also make payments and more. Here’s the documentation.

I’m still a noob and can’t find decent guides specifically for a Bitcoin payment system. It’s frustrating.

Glad to help! Just keep trying and learn as you go.
