Setting up wallet mnemonics

The truffle configuration file reads the mnemonics from a .secret file present in the truffle project directory. This is done using the following lines already present in the truffle-config.js file. These lines could be commented initially. However, you can uncomment those lines according to your needs:

const fs = require('fs');const mnemonic = fs.readFileSync(".secret").toString().trim();

The preceding script reads the .secret file from the filesystem and sets in the mnemonic variable. This variable can be used in the configuration to read the BIP39 mnemonic keyword.

If this file is not present, you should create this file under the truffle project and incorporate your BIP39 mnemonic seed keywords in plain text ...
