SecuX Hardware Wallet GRS API

Usage

import { SecuxGRS } from "@secux/app-grs";

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'/17'/0'/0/0";
     const address = await device.getAddress(path);
     
     /*
     
     // transfer data to hardware wallet by custom transport layer.
     const data = SecuxGRS.prepareAddress(path);
     const response = await device.Exchange(data);
     const address = SecuxGRS.resolveAddress(response, path);
     
     */
     

   • segwit address (default script: P2SH_P2WPKH)

     const address = await device.getAddress("m/49'/17'/0'/0/0");
     

   • legacy address (default script: P2PKH)

     const address = await device.getAddress("m/44'/17'/0'/0/0");
     

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

const inputs = [
    {
        hash: "021fd09c855a2c742b4d25bcabf7b0a93d2f81e686875d29173d2527d3f93383",
        vout: 0,
        satoshis: 489957866,
        path: "m/44'/17'/0'/0/0",
        // for custom transport layer, each utxo need publickey.
        // publickey: "030f25e157a5ddc119bf370beb688878a3600461eb5c769a5556bdfe225d9a246e"
    },
    {
        hash: "378b0fcdb5fd9b3ac93a54318ab0c5a514de7e8ab757358610c7bbda0352c544",
        vout: 0,
        satoshis: 1000000,
        path: "m/49'/17'/0'/0/0",
        // for custom transport layer, each utxo need publickey.
        // publickey: "0212f4f7e43bae1bc53ef94dbef85f8348550975f5fd8f3693c19757223692e8dd"
    }
];

const to = {
    address: "38kpyoty76H1c6wWo7cfbPYNB88RsMV8AB",
    satoshis: 400000000
};

const utxo = {
    path: `m/44'/17'/0'/0/7`,
    satoshis: 60000000,
    // for custom transport layer, each utxo need publickey.
    // publickey: "0270806ba59d0abe13f6a0a13d2997f358fca3de938aec7f52bc78e7121d24ae23"
}

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

/*

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