GoWalletApi

Go Wallet Api provides bitcoin wallet functions such as random mnemonic , HD SegWit address and multi-sig P2SH bitcoin address generation. Project consist of 3 unary RPC API and provides a reverse-proxy server which translates a RESTful HTTP API into gRPC using gRPC-Gateway.

1. Generating random mnemonic words following BIP39 standard

[GET] .../v1/wallet/random_mnemonic

2. Generate a Hierarchical Deterministic (HD) Segregated Witness (SegWit) bitcoin address from a given seed and path

[POST] .../v1/wallet/generate_hd_seg_with

Request Body:

{
  "seedPhrase": "string",
  "path": "string"
}

Response:

{
  "generatedAddress": "string"

{
  "n": 0,
  "m": 0,
  "publicKeys": [
    "string"
  ]
}

Response:

{
  "generatedAddress": "string"
}
