expo-walletsdk

ethOS WalletSDK for Expo apps.

Add the package to your npm dependencies

npm install expo-walletsdk

How to use it

You want to first check if the device is ethOS before running signMessage or sendTransaction.

Start by importing all the ethOS WalletSDK functions like this:

import * as ExpoWalletsdk from 'expo-walletsdk';

Then you can call ExpoWalletsdk.isEthOS(), which will return true if the device is running ethOS.

How to sign a message:

var signMessageParams: ExpoWalletsdk.SignMessageParams = {
    message: "Hello World"
}
var result = ExpoWalletsdk.signMessage(signMessageParams)

How to send Transactions:

var txParams: ExpoWalletsdk.TransactionParams = {
    to: "",
    value: "1000000000000000000", // 1 eth in wei
    data: ""
}
var txId = ExpoWalletsdk.sendTransaction(params)
