SecuX Hardware Wallet DGB API

Usage

import { SecuxDGB } from "@secux/app-dgb";

First, create instance of ITransport.

• Web Usb
• Web Bluetooth
• React Native Bluetooth

Examples

1. Get address by BIP32 path.

   • native segwit address (default script: P2WPKH)

     const path = "m/84'/20'/0'/0/0";
     const address = await deivce.getAddress(path);
     
     /*
     
     // transfer data to hardware wallet by custom transport layer.
     const data = SecuxDGB.prepareAddress(path);
     const response = await device.Exchange(data);
     const address = SecuxDGB.resolveAddress(response, path);
     
     */

   • segwit address (default script: P2SH_P2WPKH)

     const address = await deivce.getAddress("m/49'/20'/0'/0/0");

   • legacy address (default script: P2PKH)

     const address = await deivce.getAddress("m/44'/20'/0'/0/0");

2. Sign transaction (native segwit has not supported yet).

const inputs = [
    {
        hash: "4632c6b99925ebae5b806f5956d2d730415fe0c8c7edbfa2edea22e99a8f9f56",
        vout: 0,
        satoshis: 100000000,
        path: "m/44'/20'/0'/0/0",
        // for custom transport layer, each utxo need publickey.
        // publickey: "02d07f1bcfdc3f25b23236bf46477527b26bd383fc6c03d7050105e16325c0b401"
    },
    {
        hash: "18638cd984ab631ad7dafc5a701bec3ffa9b26bed5855eee4598d53a2ecad870",
        vout: 0,
        satoshis: 50000000,
        path: "m/49'/20'/0'/0/0",
        // for custom transport layer, each utxo need publickey.
        // publickey: "03c117cf3c09cd66bd826082ecf4fb2e322b8d97ec4bfbdc380415ca9fe0c554bc"
    }
];

const to = {
    address: "D7TwNix9ziu8k16gAcqkyKWvXhXg7tkdAC",
    satoshis: 70000000
};

const utxo = {
    path: `m/44'/20'/0'/0/11`,
    satoshis: 77777777,
    // for custom transport layer, each utxo need publickey.
    // publickey: "03efc5266e1979ada343a2271c83d1f0e9c19682bb9ddaabe10f028021781a7c01"
}

const { raw_tx } = await device.sign(inputs, { to, utxo });

/*

// transfer data to hardware wallet by custom transport layer.
const { commandData, rawTx } = SecuxDGB.prepareSign(inputs, { to, utxo });
const response = await device.Exchange(commandData);
const signed = SecuxDGB.resloveTransaction(response, rawTx, inputs.map(x => x.publickey));
