I want to launch a bitcoin wallet service website for creating new wallets.

And i want to provide a tool for user for importing their old wallets using public and private key.

I know i can use some API's like blockchain.info api and some others

But they just allow to create wallets in their system , and you can not import other wallets using their api in your account.

How can i be a bitcoin wallet service provider from scratch?

i want to let my clients create new account with new wallet address + import and exporting wallets using public and private key + send & recieve money with other wallets + etc

  • There is a standard Wallet Import Format (WIF): bitcoin.org/en/developer-guide#term-wallet-import-format utilized by the bitcoin core wallet with importprivkey and dumpprivkey – JBaczuk Oct 1 '18 at 15:13
  • @JBaczuk thanks , do you know there any easier way or API? the document does not seem friendly for development. – Net Oct 1 '18 at 15:30

    An API that lets you import private keys is very likely to be a scam. – MCCCS Oct 1 '18 at 15:41

    If you have to ask you shouldn't be doing it – Abdussamad Oct 1 '18 at 18:37
