Segwit Examples

Get Started

$ git clone https://github.com/kento1218/segwit-examples.git
$ cd segwit-examples
$ npm install
$ export SEED=`node gen-seed.js` # generate and save master key seed

Tools

Address Generation

Usage:

$ node address.js [-T] -i <address index> [-t <type>]

Script runs for testnet with -T flag (HIGHLY RECOMMENDED). -i specifies HD address index. Following types are available:

• -t normal (default): generates P2PKH address
• -t multisig: generates P2SH(2-3 multisig) address
• -t p2shsegwit: generates P2SH(P2WPKH) address
• -t p2shsegwit-multisig: generates P2SH(P2WSH(2-3 multisig)) address
• -t segwit: generates P2WPKH address (in BIP173 format)
• -t segwit-multisig: generates P2WSH address (in BIP173 format)

Transaction Signing

Describe transaction details in JSON format.

{
  "inputs": [
    {
      "tx_hash": "", // (in hex) required
      "index": 0,    // required

      "pubkey_script": "",  // (in hex) required
      "redeem_script": "",  // (in hex) for P2SH
      "witness_script": "", // (in hex) for P2WSH
      "amount": 0,          // (in satoshi) required if segwit

      "keys": [
        "m/44'/0'/0'/0/0" // at least one key required
      ]
    }
  ],
  "outputs": [
    {
      "address": "",  // P2PKH/P2SH/BIP173 address
      "amount": 0     // (in satoshi)
    }
  ]
}

Then

$ node transaction.js -T <JSON file path>

-T flag works as same as address.js.

Examples
