Yes, but a few important points.

  • Don't forget to enable txindex, it will allow you to query your node for all transactions.
  • Don't use the RPC API on the front end. RPC is needed to make transactions, but it might allow others to withdraw your coins. Keep the RPC in the back end.
  • The HTTP REST API is suitable for front end use.
  • Don't keep your funds on a client on a cloud server unless you trust them.
  • The front end shouldn't contact the node to make transactions or handle the private keys, instead, you should use BitcoinJS or Bitcore-lib to create transactions on the front end.

  • On the front end? You can hash the username and password to derive the seed, so don't store them (either in the front end or in the back end). Then you can generate addresses/private keys by applying BIP32 transformations, which should be the wallet and should be unique to each user. @salmanfaris

  • Thanks for responding @MCCCS .I understand something. But not everything. Actually what is BIP32 transaction. And how generate unique address for each users. I thing that generate address for each users by using RPC call getnewaddress .Is it correct..?
