How to implement stake.com model of deposit & withdraw flow for my crypto poker casino?

Question

In stake.com for each user they generate separate bech32 address for deposit & displays the deposited amount as balance in top of the navigation bar.

Similarly for withdraw they just ask for the amount to be withdrawn & receiver address for withdrawal.

Currently for our setup we're generating bech32 address with publicKey & privateKey using node JS. But for sending transaction to another bech32 wallet it's more complicated to calculate transaction fee & sochain.io costs too much.

Answer 1

Your question is very broad and depends on a lot of circumstances.

The most straight-forward approach to any hot web wallet is building your solution on top of bitcoin-d and the existing JSON-RPC API. (https://developer.bitcoin.org/reference/rpc/)

There are libraries for almost every language.(https://en.bitcoin.it/wiki/API_reference_(JSON-RPC)#Languages)

• Run a dedicated server/VPS
• Install bitcoin-d at your preferred version
• Update bitcoin.conf if you want pruned, also you can set walletnotify here which works like a callback that will ping or run a script of your choosing whenever funds are received to the wallet.
• Familiarize yourself with the wallet JSON RPC calls (https://developer.bitcoin.org/reference/rpc/#wallet-rpcs)

Implement into your site as necessary.
