WalletConnect provider

WalletConnect web3 provider.

Currently smart contract deployment's are commonly executed on the command line using a seed phrase that is either stored as an environment variable or local file. A better way to manage an account used to deploy smart contracts with truffle would be to remotely sign contract deployment transactions from a mobile device using WalletConnect. Instead of exposing the seed phrase or private key used for deployment on the same environment as the source code, we could instead initiate a WalletConnect session from a QR Code generate on the CLI to be scanned by a mobile wallet. After successful connection, a contract deployment transaction could be requested immediately after to the connected wallet.

Getting start

You need to install npm package

npm i wallet-connect-provider

Then you need to setup truffle-config.js

const WalletConnectProvider = require("wallet-connect-provider");

const provider = new WalletConnectProvider({
    rpcUrl: "https://rinkeby.infura.io/v3/" + process.env.INFURA_API_KEY
});

module.exports = {
    networks: {
        rinkeby: {
            provider,
            network_id: 4
        }
    }
}

WalletConnectProvider options

{
    rpcUrl: "http://localhost:8545",                // RPC url (Required)
    bridge: "https://bridge.walletconnect.org",     // wallet-connect bridge (default: https://bridge.walletconnect.org)
    shareNonce: false                               // shares nonce state across multiple provider instances (default: true)
}

Try it

In order to use, you need to have a mobile wallet with WalletConnect support. For testing purpose, you can use https://test.walletconnect.org/

You need:

1. open https://test.walletconnect.org on a mobile phone (Safari in case of iOS)
2. run truffle migrate --network rinkeby in your project
3. connect https://test.walletconnect.org via scanning QR code in a console
4. approve wallet-connect-provider in https://test.walletconnect.org
5. sign a transaction in https://test.walletconnect.org when the request appears
