Deploy your blind app to the Nillion Testnet

Your blind app is currently running locally against the nillion-devnet. Let's configure environment variables to point at the Nillion Testnet. That way anyone can play with your blind app once it's deployed.

Update your .env file and test locally​

Update your .env values to point at the Nillion Testnet

Note: for Next apps, change the prefix to NEXT_PUBLIC_

The REACT_APP_NILLION_NILCHAIN_PRIVATE_KEY private key value above should correspond to an address you've funded with Testnet NIL.

Create a Nillion Wallet and get the private Key​

Follow the Creating a Nillion Wallet guide to create your Nillion wallet. Note that when you create your wallet, you need to use the "Sign up with Google" option rather than "Use recovery phrase" option because Keplr only exposes the private key of wallets created when you "Sign up with Google."

Here's how to get the REACT_APP_NILLION_NILCHAIN_PRIVATE_KEY value from a Nillion wallet created with a Google account:

Fund the Nillion Wallet address that corresponds to your private key​

Follow the Nillion Faucet Guide to learn how to get Testnet NIL to fund the Nillion wallet address that corresponds to your private key. This way your app can pay for operations.

Test the configuration locally against your blind app to make sure the full blind computation flow is working as expected.

Set Headers and set up proxy for nilchain​

The JavaScript Client makes use of browser web-workers. To make your app cross-origin isolated, you'll need to set COOP and COEP headers, completed for you in the cra-nillion webpack.config.js

Cross-Origin-Embedder-Policy: require-corp
Cross-Origin-Opener-Policy: same-origin

Add headers and create a nilchain proxy in your webpack.config.js

module.exports = {
  devServer: {
    static: {
      directory: path.join(__dirname, 'public'),
    },
    headers: {
      'Cross-Origin-Embedder-Policy': 'require-corp',
      'Cross-Origin-Opener-Policy': 'same-origin',
    },
    hot: true,
    client: {
      overlay: false,
    },
    historyApiFallback: true,
    proxy: [
      {
        context: ['/nilchain-proxy'],
        target: process.env.REACT_APP_NILLION_NILCHAIN_JSON_RPC,
        pathRewrite: { '^/nilchain-proxy': '' },
        changeOrigin: true,
        secure: false,
      },
    ],
  },
};
