SecuX Hardware Wallet ETH API

Usage

import { SecuxETH } from "@secux/app-eth";

First, create instance of ITransport

• Web Usb
• Web Bluetooth
• React Native Bluetooth

Examples

1. Get address derived by given BIP44 path

const address = await SecuxETH.getAddress(device, "m/44'/60'/0'/0/0");

1. Sign legacy transaction

const { raw_tx, signature } = await SecuxETH.signTransaction(
    device,
    "m/44'/60'/0'/0/0",
    {
        nonce: 0,
        to: "0xD080156885651fADbD6df14145051b934660a748",
        value: 1e10,
        chainId: 1,
        gasPrice: 1e6,
        gasLimit: 1e6
    }
);

1. Sign transaction with Smart Contract (ERC-20)

const { raw_tx, signature } = await SecuxETH.signTransaction(
    device,
    "m/44'/60'/0'/0/0",
    {
        nonce: 0,
        to: "0x1f9840a85d5af5bf1d1762f925bdaddc4201f984",
        value: 0,
        data: "0xa9059cbb000000000000000000000000d080156885651fadbd6df14145051b934660a7410000000000000000000000000000000000000000000000000000000000989680",
        chainId: 1,
        gasPrice: 1e6,
        gasLimit: 1e6
    }
);


// transfer token easy use
const { raw_tx, signature } = await SecuxETH.signTransaction(
    device,
    "m/44'/60'/0'/0/0",
    {
        nonce: 0,
        to: "0x1f9840a85d5af5bf1d1762f925bdaddc4201f984",
        value: 0,
        data: {
            toAddress: "0xD080156885651fADbD6df14145051b934660a748",
            amount: `0x${1e18.toString(16)}`
        },
        chainId: 1,
        gasPrice: 1e6,
        gasLimit: 1e6
    }
);

1. Sign Message transaction

const { raw_tx, signature } = await SecuxETH.signMessage(device, "m/44'/60'/0'/0/0", msg);

1. Sign TypedMessage transaction

const { raw_tx, signature } = await SecuxETH.signTypedMessage(device, "m/44'/60'/0'/0/0", msg);

1. Sign transaction with WalletConnect

const { raw_tx, signature } = await SecuxETH.signWalletConnectTransaction(
    device,
    "m/44'/60'/0'/0/0",
    {
        nonce: 0,
        to: "0xD080156885651fADbD6df14145051b934660a748",
        value: 0,
        data: "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",
        chainId: 56,
        gasPrice: 1e6,
        gasLimit: 1e6
    }
);

Note

1. Value of chainId (same as EIP-155):
   • Ethereum Mainnet: 1
   • Binance Smart Chain Mainnet: 56
2. Support for EIP-1559 coming soon
